The software reads in the material data and airfoil data of the wind turbine blade, and automatically constructs the geometry and finite element mesh for the blade. In a next step, the nodal and element information of the finite element mesh is written out to an input file for a commercial finite element solver (Abaqus in this case). As such, all features of a state-of-the-art finite element solver can be used to simulate the mechanical behaviour of the composite blade.<br />The concept of the BladeMesher software is described in the journal paper "Peeters, M., Santo, G., Degroote, J. and Van Paepegem, W. (2018). High-fidelity finite element models of composite wind turbine blades with shell and solid elements. Composite Structures, 200, 521-531" (<a href="https://doi.org/10.1016/j.compstruct.2018.05.091" target="_blank" rel="noopener noreferrer">https://doi.org/10.1016/j.compstruct.2018.05.091</a>).<br />The BladeMesher software is programmed in the Python language and counts more than 30,000 lines of code.</p>
<p align="justify">In this project, the BladeMesher software is further developed to include additional features for detailed modelling of adhesive joints (with cohesive elements). Further the computational mechanics of thick adhesive joints will be studied by finite element modelling. The properties of the bulk adhesive and interaction with the composite substrates will be included in the FEM models.<br />The project is funded by FWO-Vlaanderen and is a collaboration between Ghent University, Free University of Brussels (VUB) and EPFL (Lausanne, Switzerland). The researcher at Ghent University will be closely collaborating with two other PhD students at VUB and EPFL.<br />The research study at Ghent University is purely numerical, while the experimental work will be done at the two other universities.</p>

<p><span><strong>Project description:</strong></span></p>
<p>In the context of underground engineering (e.g.: transport, deep disposal, etc.), the design of the support is crucial in order to ensure the stability and sustainability of the structures. If their structural integrity is not maintained, operational difficulties or loss of stability of the underground structure may occur. This stability is mainly conditioned by the rheological behaviour of the excavated rock mass, the structural behaviour of the gallery supports, and the excavation process. Particular 3D geometries (intersections of galleries or tunnels) and particular anisotropy conditions (in situ stress anisotropy, structural anisotropy of the rock) make the stability study of underground structures particularly complex. These aspects remain not well investigated in the field of underground constructions.</p>
<p>The objective of the project is to study the stability of gallery intersections, drilled at great depth in rock, through a numerical approach. Numerical modelling will be carried out by finite element method. The stability will be analysed regarding the behaviour of the support structure and the surrounding rock. The carried-out studies should consider:<br />- The geological context and the properties of the materials involved (anisotropies of geostatic stresses and of the material fabric).<br />- The fractured zone likely to develop (plasticity and rupture) around the structure during its construction phase. A 2D and 3D elastoplastic law able to reproduce the structural anisotropy of the material and its damage will be implemented.<br />- The behaviour of complex 2D/3D retaining structures of tunnel intersection and their design. The rheological and structural model will be validated based on in situ measurements around gallery intersection during their drilling. The expected results include the reproduction of the stress redistribution around the structure, the deformation and loading of the support, the gallery convergence, and the development of the fractured zone.</p>
<p><span><strong>Application:</strong></span></p>
<p>Candidates can apply for a 3-year PhD scholarship at University of Lyon (ENTPE engineering school, LTDS laboratory), co-supervised by an industrial partner. Candidates must come from the <span>European Union</span> and have a Master / Engineer degree in the fields of civil engineering, underground works, mechanics of materials or of structures. The research project requires a basic knowledge in geotechnics, underground works, constitutive modelling, continuum mechanics, and an interest in numerical modelling in geomechanics. The project will give the applicant the opportunities to develop various skills (advanced numerical methods, rock mechanics, elastoplasticity, damage approach, structural design, etc.) and to integrate a dynamic geomechanics network having a large experience in underground studies and numerical modelling. The ability to communicate orally and write in English is required and European mobility is encouraged.<br />Applications should be submitted by the 10th of March 2021 by emailing a CV, academic grades (detail of marks), scientific/academic references, and recommendation letter to the supervisors (see attached document). Any additional document relevant for the application can also be transmitted. The scholarship of the successful applicant is due to start on the 1st October 2021.</p>

<p><span><span>At the Department of Materials Engineering, Faculty of Engineering Technology at KU Leuven, we develop and study new materials and processes to shape these materials. Changing the microstructure of a material allows developing materials with new characteristics, which leads to new applications. Inside MeM2P group (Mechanics of Materials, Products and Processes), our current research lies in the interface between applied research (service to industry) and knowledge-driven research (theoretical-abstract). In particular, our research focuses on contact mechanics, fatigue, fracture mechanics and impact of metals in engineering applications.</span></span></p>
<p><span><strong>Project</strong></span></p>
<p><span>Additive manufacturing (AM) is becoming a game-changing technology with enormous potential impact on the range of available designs, enabling new component capabilities that cannot be realized with any other technology andreducing lead-times, storage and transportation costs. Among different available AM technologies, Selective Laser Melting (SLM) is a powder-bed based technique which is very popular. The successful construction of additively manufactured metallic components for safety-critical applications requires athorough understanding of metallurgical structures, residual stresses and associated mechanical properties. Fatigue fracture assessment of SLM components is well-documented in the literature. However, there is very little research work focusing on tribo-mechanical properties of SLM components, such as fretting fatigue phenomenon.</span></p>
<p><span>By definition, the fretting fatigue occurs when two contacting parts slip over each other at a micro level while being subjected to an external fatigue loading conditions. When compared to a plain fatigue problem, fretting fatigue reduces the lifetime of a part by half. This phenomenon is a complicated task, because of the fact that the contact stresses at the contact interface are multiaxial. To this end, depending on the multiaxiality and non-proportionality of the stresses at the contact interface, the response of the material is different. This failure mode happens in many industrial applications such as automotive parts, fasteners, bearings shafts, steam and gas turbines’ blades. Many of these applications such as steam and gas turbines’ blades are potential applications for AM technology. Therefore, correct assessment of the fretting fatigue response of additively manufactured parts is very important for safety-critical applications such as gas turbines’ blades.</span></p>
<p><span>This research project focuses on behaviour of additively manufactured metal parts when subjected to the fretting fatigue loading conditions using both experimental testing and advanced numerical modelling. The project is sponsored by the KU Leuven internal funding scheme BOF (FLOF- Doctoraatsbeurzen). The research work is a collaboration between the Department of Materials Engineering and the Department of Mechanical Engineering.

<p>I am trying to simulate material dumping process from shovel onto mining dump truck. And for that i am using Abaqus/Explicit. When i plot the contact force of material falling onto truck body under gravity, it gives me the maximum value of 0.12e+11, where as a simple theoretical analysis shows that the resulting impact force for 100 tons of material falling under gravity should be 9e5 N. I am not been able to understand the reason that why Abaqus /Explicit is exaggerating the impact/contact force so much. And i dont know how to correct this thing.</p>
<p>Units are as follows:</p>
<p>Mass= kg</p>
<p>Distance/Displacement = mm</p>
<p>Kindly help me out in this situation.</p>
<p>Thanks,</p>
<p>Danish</p>
