Computational Biomechanics for Medicine IX: a MICCAI 2014 satellite workshop. First call for papers

Submitted by adwit on

This year we are again organising the Computational Biomechanics for Medicine (CBM) Workshop (http://school.mech.uwa.edu.au/CBM2014/) together with the Medical Image Computing and Computer Assisted Intervention Conference (MICCAI) (http://www.miccai2014.org/). This year, the workshop will be hosted by Massachusetts Institute of Technology (MIT), Boston, USA, on 14th September 2014.

 

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

Submitted by Mohammad Refat… on

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

Will structural disorder in amorphous material change under mechanical loading?

Submitted by Aman Haque on

I would appreciate your comments or pointing to something in the literature on whether mechanical loading changes the magnitude of structural disorder (may be rdf could be a measure) in amorphous materials. Does tension increase 'amorphous-ness' and is the opposite true for compression? Since the network structure is random, should tension and compression yield the same effect (if any)? 

I am assuming elastic loading/unloading only. 

 Many thanks!!

Modeling associative Tresca plasticity in ABAQUS?

Submitted by mmd110 on

Hi

I have a simple question. How could I model associative Tresca plasticity in ABAQUS?

 I use Property module: material editor: Mechanical:Plasticity:Mohr Coulomb Plasticity

I know that In the case (friction angle=0) of  the Mohr-Coulomb model reduces to the pressure-independent Tresca model with a perfectly hexagonal deviatoric section. 

Applying Periodic Boundary Conditions(PBC) in Abaqus

Submitted by bernad on

Hi all,

     I am looking for some reference on procedures for applying  PBC in  abaqus? I coud find some journal articles for the equation, but I am unaware of applying this into Abaqus under displacement laoding conditions..

any help in this regard would be appreciated greatly..

 

Thanks,
