Is the CST element more accurate than bilinear element (Q4) for bending problems?
I did a 2D beam bending problem with CST and Q4 element, respectively. CST gives better accuracy. Is it due to the shear locking effect with Q4?

FSI issue in abaqus co-simulation: misaligned nodes

Hi everyone,
I am performing FSI simulation under abaqus.
The simulation consists in a porous solid (elastic isotrope and homogeneous under Abaqus/explicit) filled by a non newtonian (viscous fluid under Abaqus/CFD). The whole is contained in a cubic shell in order to apply proper boundary condition.

Symposium on New Developments in Defect Mechanics - a unique intellectual event
Faculty from Caltech, UC Berkeley , University of Michigan, Georgia Tech, Brown University, University of Calgary, University of Pennsylvania, UCLA, Johns Hopkins University, Imperial College, London, and UCSD and researchers from the Lawrence Livermore National Laboratories congregated to UCSD on January 18-19, 2014 to attend the third in a series of symposia on Multiscale Dislocation Dynamics and to honor Professor Michael Ortiz on his 60th birthday. Faculty also brought their graduate students and postdocs to engage in such a powerful intellectual activity.
Comparing experimental fracture properties and micromechanical (or global-local/multiscale) finite element simulations
I am interested in developing a global-local finite element model (micro/macro) to simulate flexural testing of a composite material. Flexural loading will be applied on global model (macro) and crack propagation will be simulated in the local model (micro). I want to compare stress intensity factor or any other fracture property obtained from local model (micro) with that of experimental results.
I would appreciate if anyone could suggest some references/literature in this area. Any kind of suggestions would be great!

Microplane modeling of shape memory alloy tubes under tension, torsion, and proportional tension–torsion loading
In this paper, a phenomenological constitutive
model based on microplane model is used to simulate tension, torsion and proportional tension-torsion on NiTi thin-walled tube. Validation of the
microplane model against experimental results in different loading conditions demonstrates
the capability of this approach.
This publication will benefit the numerical and experimental study on SMAs.

Hello all,
I am interested in using a finite element software in a supercomputer setting (i.e. bluegene, cray, etc.). Does anyone have experience running finite element solutions on massively parallel supercomputers? What solvers are most amenable to such a task?
