How to simulate torsion of cylinder in ANSYS?

Submitted by sspadhee on

I want to model torsion of a homogeneous hollow cylinder in ANSYS. I changed to cylindric coordinate system also. But each time I run the program  the result is that of bending. I have attached the mac file and output file for reference. Please advise.

Virtual Heart Surgery

Submitted by ADINA Support on

1. We highlight a study performed by researchers using ADINA in which they investigated a computational approach to construct patient-specific ventricle models based on in vivo cardiac magnetic resonance (CMR) imaging for surgical planning and optimization. The study was motivated by the fact that the use of such computational models can help to assess different surgical hypotheses and replace empirical and perhaps risky clinical experimentation.

Research associate position at University of Sheffield

Submitted by CanhLe on

The successful candidate will work on the EPSRC funded research project 'Ultimate and permissible limit state behaviour of soil-filled masonry arch bridges', which is being undertaken in collaboration with the University of Salford and various industrial partners (Network Rail, ADEPT, the International Union of Railways and Balfour Beatty Rail). This is an exciting opportunity to help develop the next generation of analysis and assessment techniques for masonry arch bridges, thus helping to ensure a sustainable future for structures that continue to form a vitally important part of the rail and regional road networks of the UK and other countries.

code error144 and umat isotropy hardening law

Submitted by lamjuv on

hello everybody
i want to develop a constitutive law for fiber reinforced composite. so i am using umat subroutine to simulate it in abaqus.
when i begin analysis i got error code 144.
my question is: is jacobian matrix DDSDDE can be to cause for this error??

and i read that i can use uhard subroutine for isotropic and combined hardening.
using this subroutine we can get yield surface from hardening curve, so we must enter some value in abaqus^material^(yield stress with corresponding strain)

A Field Theoretic Approach to the Quasi-Continuum Method

Submitted by Vikram Gavini on

Dear Colleagues,

I wish to bring to your attention my recent work with Mrinal Iyer on a field theoretic approach to the quasi-continuum method to appear in Journal of the Mechanics and Physics of Solids. Below is the abstract and attached is the preprint of the article. I will very much appreciate your comments and suggestions.
