Hello,
My question is about using second order elements in a 3D problem. Imagine that we are appling bending moment on a beam. If we only use 1element in the thickness, I dont understand why:
1) in reduced integration element (C3D20R) we still have hourglassing
2) in full integration element (C3D20) we still have shear locking.
Thanks
Hello,
I was wondering how is it possible to implement incompressible neohookean material in abaqus?
With the incompressibility assumption c(3,3)=1/(- c(1,2)^2 + c11*c22), with c being the Cauchy-Green strain tensor. It also implies that S33=0 and it is possible to find the pressure directly. In addition, h=sqrt(c(3,3))*h0 with h and h0 being current and initial thickness, respectively.
my question is that how is it possible to implement the last condition in umat?
On behalf of the Organisers, I wish to post the following message:

Postdoctoral Fellow Position: Computational simulations of brittle failure
A postdoctoral position is available at The Johns Hopkins University. The position is in the area of damage-based constitutive modeling and computational simulations of brittle failure. This postdoc position is in Hopkins Extreme Materials Institute (hemi.jhu.edu). The potential candidate should have a Ph.D. in engineering or a science discipline.
We would be hard-pressed to find an area of research that permeates so deeply in nearly all branches of physical sciences and mathematics as does the topic of homogenization [1].
Multiple faculty positions are available in School of Mechanical Engineering and Automation, Fuzhou University, Fuzhou, Fujian，China.

A PhD position is open for summer or fall 2017 in Advanced Hierarchical Materials by Design Lab at Louisiana Tech University on multiscale modeling of materials for energy applications with emphasis on ferroic materials. The candidates must have earned a M.Sc. degree in Mechanical Engineering or related fields and have a solid background in theoretical and computational mechanics, specifically continuum mechanics and finite element modeling, and need to be familiar with a programming language (preferably C/C++).
