microstructure-sensitive modeling

in situ experiments

The Adv. Computational Materials and Experimental Evaluation laboratory at Purdue University’s School of Aerospace Engineering invites applications from highly motivated individuals for a postdoctoral position. This position is supported by a 2 year sponsored project from DARPA that seeks to advance the development of time dependent behavior of aerospace alloys.

High temperature material behavior in Abaqus

Submitted by qwerty on Mon, 07/28/2014 - 21:24

I need to simulate high temperature behavior of a metal in Abaqus. I have J-C parameters (A,B,C, n,m, epsilon_dot, melt temp, transition temp). Where to specify the test temperature in Abaqus ?

Thanks

modeling crack surface friction in abaqus

Submitted by aapaaapa on Sun, 07/27/2014 - 18:16

Hi every one,

I need to consider friction in crack surface and observe its effect on my answer. I want to do it in abaqus. how can I model friction in that surface, because I can identify interaction just for external surface. I am so grateful.

thanks

The UMAT problem with no strain and stress

Submitted by atefe.geramian on Sat, 07/26/2014 - 18:21

Hello,

I have written a UMAT subroutin. When I run, the job completes succssefully. But when I try to see results from the ODB files, I get the following error:

"The selected primary variable is not available in the current frame for any elements in the current display group"

I have tried to select the stress, strain and magnitude and all not available. Could anybody help me?

Thanks in advance for your help.

Best regards,

viscoelastic material using Ansys for Dynamic modeling

Submitted by Veerabhadrayya… on Sat, 07/26/2014 - 16:39

Hello,

I am planing to model a viscolestic material in ANSYS and condition is dynamic.

i have the data of stress relaxation data from experimental Could anyone please suggest how to give material input in ansys taking the data of stress relaxation

weather for dynamic modeling of viscoelastic material in ansys, we should go for curve fitting or prony series

Thanks for your kind help
