Yield behaviour of trabecular bone

A recently published paper  "Evaluating the macroscopic yield behaviour of trabecular bone using a nonlinear homogenisation approach" links the micromechanics of bone to its macroscopic behaviour. The paper may be of interest to colleagues on this forum. The abstract is provided below.

Simulation-based numerical optimization of arc welding process for reduced distortion in welded structures

This paper presents an effective numerical approach for welding process
parameter optimization to minimize weld-induced distortion in
structures. A numerical optimization framework based on coupled Genetic
Algorithm (GA) and Finite Element Analysis (FEA) is developed and
implemented for a low and a high fidelity model. Classical weakly
coupled thermo-mechanical analysis with thermo-elasto-plastic
assumptions is carried out for distortion prediction of numerical
models. The search for optimum process parameters is executed by direct
integration of numerical models and GA-based optimization technique. The
developed framework automatically inserts the process parameters into
the simulation models, executes the FE-based welding simulations and

Online finite element analysis of nanoindentation (indentation)

Dear All, 


We (the NanoBIO Node at Illinois ) have a preliminary release of an online finite element analysis of nanoindentation (indentation) tool using FEAP

Radiation in 1D beam finite elements

Hi everyone,


Has anyone ever come across the treatment of radiation heat transfer in one-dimensional beams using FEM ? Convection and conduction are well established, but I was wondering whether radiation is still an open area of research?

 Any links to publications would be very much appreciated, Thank you

PhD position in multi-scale modeling for robust-design of vibrating micro sensors

 The project

This project aims at improving the efficiency of the manufacturing process of MEMS while decreasing the production cost by considering at the design stage the uncertainties in such a way that a range of the MEMS properties can be predicted for the manufactured products, which will be immune to factors that could adversely affect performance. This approach is called robust design and it is focused on achieving target reliability.

Problems with numerical integration of discontinuous functions

Choose a channel featured in the header of iMechanica: 

Hi everybody,

 I am a very beginnerin doing research :-) and my topic is about "micro indentation analysis using continuum dislocation theory". I am applying high-order finite element method for this nonlinear problem.

My plan is first writing a subroutine for the element. However, when I intend to compute the internal force by using Gauss integration, I see a problem with the integrand function of some index of the internal force vector. This integrand is discontinuous function. It is therefore, I cannot get a good approximation with the standard Gauss integration.
