PhD positions in my ERC project

Submitted by azadpoor on

I was recently awarded an ERC grant for which I will be hiring up to five new PhD students with different types of expertise. Actual hiring will take some time, as new researchers are needed at different stages of the project (not all PhD students will start at the beginning of the project). Interested candidates with the following backgrounds and skill sets are encouraged to contact me directly at azadpoor [at] gmail.com

composite fiber angle definition

Submitted by r_n_s_s on

Dear imechanicas,

When composite plates with cutouts are meshed, the mesh scheme around the hole is somehow not in a mapped shape. This means the edges of (for instance a four-node element) in undeformed shape are not in a rectangular format. Therefore, defining the constitutive equations of orthotropic materials might lead to incorrect results.

Does anybody have opinion/experience about this issue?

Any response is appreciated.

Regards

Stress vector plot in ANSYS classic

Submitted by PRITI YADAV on

Hello all,

I am using ANSYS classic for structure analysis.I have two load steps and I need to define the element coordinate systems for selected elements ( in 2nd load step) aligned with principal stress directions obtained from 1st load step.

Earlier I did this in workbench and there I was extracting the principal stress vector data for 'elemental mean' (shown in attached figure) and then in 2nd load step creating the local coordinate system using THXY, THYZ and THZX data. Then assigning this local coordinate systems to appropriate elements.

Computational analysis of metallic nanowire-elastomer nanocomposite based strain sensors

Submitted by mortezaamjadi on

Possessing a strong piezoresistivity, nanocomposites of metal nanowires and elastomer have been studied extensively for its use in highly flexible, stretchable, and sensitive sensors. In this work, we analyze the working mechanism and performance of a nanocomposite based stretchable strain sensor by calculating the conductivity of the nanowire percolation network as a function of strain. We reveal that the nonlinear piezoresistivity is attributed to the topological change of percolation network, which leads to a bottleneck in the electric path.

Application of Corotational Formulation

Submitted by Dario Schiano … on

Hello,  I am a PhD student in Mechanical Engineering, and at the moment I am studying the co-rotational formulation from Criesfield's books.

I am looking for applications of the corotational formulation in ABAQUS or MATLAB; my supervisor suggested me it could be done in ABAQUS through a User Defined Element Subroutine, but being a new user to this software I don't really know from where I should start.

Post Doctoral Researcher in Microstructural Modelling of Materials

Submitted by Noel ODowd on

A post doctoral position is available at the University of Limerick, Ireland. The object of the research, which is funded by Science Foundation Ireland (SFI), is to obtain an understanding of the mechanical behaviour of ferritic and martensitic steels at the micron and sub-micron scale and to link this behaviour to component behaviour. The work will involve computational and experimental studies of material behaviour using a range of numerical and experimental techniques.
