Plasticity

Dear Colleague:

You are cordially invited to attend Nanobrücken II: A Nanomechanical Testing Workshop, jointly presented by INM - Leibniz Institute for New Materials and Hysitron, Inc., with co-sponsorship from the JEOL company. This is the second workshop in the Nanobrücken series. The workshop's scope has been broadened, and the abstract submission deadline is now February 19, 2012.

Postdoctoral postion in Computational Crystal Plasticity at RPI

Submitted by Suvranu De on Wed, 01/04/2012 - 18:33

job

There is an immediate opening for a postdoctoral research position in the Advanced Computational Research Lab at RPI, Troy NY to work on Crystal Plasticity Finite Element Methods. Currently we are working on interesting advances in the areas of radiation damage and high strain rate loading conditions. Encouraged to apply are creative, self-motivated individuals with a sound baclkground in computational mechanics, CPFEM and materials science. RPI is home to the CCNI, one of the most powerful university-based supercomputational research facilities in the world.

What is the basic difference between Deformation theory and flow theory of plasticity ?

Submitted by Suman.Guha on Tue, 12/06/2011 - 12:46

I am familiar with the flow theory version of the plasticity theory but still quite confused with the deformation theory version of the same.

When a material is modeled using a non-linear elastic model to predict its plastic behavior with no distinction between the elastic and the plastic strain, is it a deformation theory in that case?

Any elaboration in this regard would be really helpful.

Thanks in advance.

User subroutines in ABAQUS

VUHARD

Hello

I am working on the simulation of ring rolling. I have written the subroutine for the plasticity part in the subroutine VUHARD and have set the PLASTIC part in material definition to USER.

I dont have HARDENING PROPERTIES so i have set it BLANK. i have set the path of the subroutine in the job defintion part too. But abaqus crashes whenever i try to do DATA CHECK

It says ABAQUS KERNEL EXITED WITH AN ERROR.I dont know why this problem arises?. I am stuck.

Following our previous work on Cu-Zr nanowire system, in this paper we have shown improvement in various thermo-mechanical properties of nanowire via manipulating the surface atoms. The paper titled "Designing copper–zirconium based nanowires for improving yield strength and plasticity via configuring surface atoms" by Vijay Kumar Sutrakarand D Roy Mahapatra has been published in Journal of Nanoparticle Research.
