PhD and Postdoc Positions-Department of Mechanical Engineering at the University of Texas at Dallas

Submitted by Majid Minary on Sun, 07/08/2012 - 22:57

There are openings for PhD students and Postdocs within the "UT-Dallas Nanobiomechanics Laboratory".

The research topics cover: Nanobiomechanics, scanning Probe microscopy, bioinspired and biomimetic nanomaterials, nanomechanics of living cells and biological systems, nanomanufacturing and microfabrication. The topics are "Experimental" in nature, and prior experimental skills at the nanoscale are highly desirable.

As you may know wave propagation in circular cylinders is dispersive. As shown by Pochhammer, there

could be several different modes propagating in an infinite cylinder with

different wave speeds. I'm modeling wave propagation in a finite 3D circular cylinder in

Does anyone ever work with boundary layer formulation model for crack analysis using abaqus CAE? I really need some input on that. thank you

Johnson Cook Model

fiber composites

Is it possible to use a Johnson-Cook method to predict the fiber damage in a composite lamina? I am presently using ABAQUS for it. I want to capture fiber failure.

Finite Element Method

Spectral Element Method

Hi,

Is there a free/open-source mesher for the Spectral Element Method?

I know some researchers use conventional mesher with order 3 elements and then include more nodes in the meshes (but without improve the geometric interpolation).

Thanks in advance,

How difference between Static analysis and Dynamic analysis in ABAQUS

Submitted by Sutham_eng on Thu, 07/05/2012 - 09:32

Dear everyone,

Could anyone please explains to me how difference between Static (General) analysis and Dynamic (Explicit) analysis in ABAQUS?

In my case, I have already created subroutine VUMAT for Dynamic Explicit analysis. So, is it possible to use the same code (same algorithm) for creating UMAT in Static General analysis?

Thank you very much indeed

Sutham A.
