Debonding of web and flange connection of FRP I-beam

Hello everyone

I want to model the contact non-linearity between flange-web connection of FRP I-beam. I have modeled the flange and web of 3D deformable of shell element. I can't use VCCT technique between flange-web connection because it is based upon two surfaces not on one edge (i.e. web) and one surface (i.e. flange).

Kindly give some guidance to model the debonding of flange and web of I-beam.

Expansion of a function into a basis set

Consider a ``neat'' function such as what an engineer is most likely to use in his typical theory/work. Such a function would typically be: (i) defined over a single finite interval, (ii) continuous throughout, and (iii) smooth enough. In other words, the sort of a function they used when they introduced the very idea of a graph of a function to you, back in high-school. ... Feel free to add any other qualifications you like, but note them explicitly, e.g., (iv) bounded throughout, and (v) periodic.

Prof. Yaakov Benveniste, Tel Aviv University

It is with great sorrow that I heard that our colleague from tel Aviv University, Prof. Y. Benveniste passed away recently. This is a great loss for the Israeli Mechanics Community in particular and for the community in general. I am sure he will be remembered as an exceptional scientist and a very modest and kind person.

He will be missed.

To his family, I adress my sincere condolences

A new paper on Hencky-logarithmic strain by Prof. Neff

Dear Colleagues:

I thought the following recent paper by Prof. Neff may be of interest to some of you.

http://arxiv.org/abs/1505.02203

This paper discusses the natural appearance of the  Hencky-logarithmic strain tensor together with the Hencky strain energy, which can be motivated from some purely geometrical (kinematical) arguments based on the geodesic distance on the general linear group of all invertible tensors GL(n).

Inverse distance weighting as a FEM shape function

Hello there!

I was thinking to use inverse distance  interpolation technique as a finite element shape function. However, am not sure about its performance for finite element method, inverse distance interpolation was originally developed for geographic information system.

can anyone help me please?

thanks in advance!

Postdoc Position in Computational Mechanics - Ohio State University

The Automated Computational Mechanics Laboratory (ACML) at The Ohio State University has an immediate opening for a one-year postdoctoral research associate position. The project is aimed at the application of the finite element method for simulating and optimizing the multiphysics laser ablation process in aircrafts. The optimization process involves characterizing the optimal laser parameters (e.g., peak power, fluence, intensity, etc.) to maximize the coating removal efficiency while minimizing damage to the substrate material.

Abaqus-Meshing Octagonal Part- Face Angle less than 45 degrees

I am modeling an octagonal foundation in Abaqus. The foundation is 3.1 m in height. By its geometry, foundation has got slopes with face angle less than 45 degrees. As a result, when I mesh my model, I get a warning which says that distorted elements have been detected. This is around 25% of total no of elements. How can I partition/seed, etc. to reduce the no of distorted elements? I cannot compromise on the geometry of foundation. Attached is the mesh photo and distorted elements are highlighted.

Post-doctoral Researcher in Advanced Modelling (TU Delft)

 Job description 

As systems become more complex and multidisciplinary, design of these systems also becomes more complicated. To assist design of such systems, physical models and computational tools are needed for their analysis and optimisation. The SOM group's research focus is on the development of such advanced (computational) design techniques, combined with the understanding and design of innovative mechanical devices in precision and microsystems engineering. 

Finite Element Model of the Knee

Hello Everyone,

I recently started to do a project on a FE knee model. Right now, the only available software for me is SolidWorks which was originally purchased for CAD modelling. I was wondering if anyone knows whether SolidWorks FE feature is "good enough" for analyzing a knee model (and for other tissues just in case), or you recommend me to push my supervisor to purchase a license of a "Real" FE software such as ABAQUS. If you have any experience of FE modelling of tissues,bone,etc. I would appreciate if you help me out.

PhD Studentship: "Advanced Virtual Prototyping for Sustainable Energy Generation"

I have an EPSRC CASE PhD Studentship on offer that is co-funded by Alstom PLC.

There are three aims: (i) to couple ParaFEM with OpenFOAM for massively parallel fluid-structure interaction; (ii) to release that code into the community and (iii) to use the new capability to study the performance of "whole" wind farms, insilico.

Fracture strength of micro- and nano-scale silicon components

Silicon devices are ubiquitous in many micro- and nano-scale technological applications, most notably microelectronics and microelectromechanical systems (MEMS).  Despite their widespread usage, however, issues related to uncertain mechanical reliability remain a major factor inhibiting the further advancement of device commercialization.  In particular, reliability issues related to the fracture of MEMS components have become increasingly important given continued reductions in critical feature sizes coupled with recent escalations in both MEMS device actuation forces and harsh usage

Link Ansys with Matlab

I want to do optimisation in Matlab by linking it to Ansys.

I need to get my graph from Ansys in each itteration and import the graph in Matlab in order to compare with experimental results and get new coefficients. These coefficients again needs to import in Ansys file.

 

I could manage to do it with smaller size file (with less degree of freedom), but when it comes to complicated geometry with more nodes and elements number, I got liscence problem. It looks like there is a limitation in running when you call Ansys from Matlab.

New Master's program "DESIGN des MATÉRIAUX et des STRUCTURES" at MINES ParisTech (in French)

The Centre for Material Sciences (MINES ParisTech) opens a new master program (450h of courses + internship in the industry). The majority of courses are tought in French, so this program might interest french students finishing their master courses this summer (2015) or french-speaking foreign students holding a degree equivalent to the french master. We are looking for motivated candidates!

Sensitive and stable strain sensors based on the wavy structured electrodes

Herein, we develop capacitive type strain sensors composed of the CNTs-PDMS nanocomposite thin films as electrodes and PDMS dielectric layer. The strain sensing performances of the strain sensors made of the flat and wavy structured electrodes are compared. Both types of strain sensors can measure strains up to 100%. We found that wavy structured based strain sensors possess higher sensitivity with quite stable and reliable responses due to the resistance stability and very low resistance standard deviation of the wavy structured electrodes.

Ag@Ni Core–Shell Nanowire Network for Robust Transparent Electrodes Against Oxidation and Sulfurization

Silver nanowire (Ag NW) based transparent electrodes are inherently unstable to moist and chemically reactive environment. A remarkable stability improvement of the Ag NW network film against oxidizing and sulfurizing environment by local electrodeposition of Ni along Ag NWs is reported. The optical transmittance and electrical resistance of the Ni deposited Ag NW network film can be easily controlled by adjusting the morphology and thickness of the Ni shell layer.

Highly Stretchable and Sensitive Strain Sensor Based on Silver Nanowire–Elastomer Nanocomposite

The demand for flexible and wearable electronic devices is increasing due to their facile interaction with human body. Flexible, stretchable and wearable sensors can be easily mounted on clothing or directly attached onto the body. Especially, highly stretchable and sensitive strain sensors are needed for the human motion detection.
