Crack Propagation by XFEM
Hai everyone.
Good day, i'm a new to XFEM who currently doing research in electronic field. I'm thinking about since the crack can be propagated without a crack tip by strain loading, how about the crack propagation by using thermal loading? I didn't see any example of this kind of problem, so can anyone tell me is that possible to do such simulation? Your suggestion is important for me and will be highly appreciated.
Thanks in advance.

Nodal stress and strain history output from Abaqus
Hi everyone,
I am trying to get the history output of strain and stress tensor components at a node. However after analysis is finished no such data are saved in the result section. I think Abaqus only gives the stress and strain for elements and not at nodes. Any help would be highly appreciated. Please consider that I am a new abaqus use.
Thank you in advance
Computational Biomechanics for Medicine IX: a MICCAI 2014 satellite workshop. First call for papers
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
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?
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!!
