Post-Doctoral Position at the University of Texas at Austin

Submitted by Ravi-Chandar on

The Research Center for Mechanics of Solids, Structures and Materials at the University of Texas at Austin invites applications for two open positions as Post-doctoral Fellow. The specific projects involve (i) the characterization of the constitutive and failure behavior of structural materials (aluminum alloys, steels, titanium alloys and other selected materials) under quasi-static and dynamic conditions, and (ii) the characterizaation and modeling of the dynamic response of metal-matrix composites. These positions are available immediately.

Matlab - ANSYS interface

Submitted by nabeel963030 on

Hi 

I am woking on an optimization problem. In this optimization problem I want to use Matlab and ANSYS.  In which MATLAB  initiating the optimization problem, and  send input values to ANSYS, then ANSYS find some results and send it to Matlab...then continue the optimization process.

Can any one help me to do these comunications between Matlab and ANSYS?

Indentation Stress and Displacement Fields

Submitted by Jay Palaniappan on

I am looking for stress and displacement fields for indentation of an elastic half-space with a rigid spherical indenter. Anthony C. Fischer-Cripps provides closed form expressions (no derivations) for stress fields in his textbook "Introduction to Contact Mechanics" (Chapter 5, Page 88-89). He cites the work of M.T. Huber[1] which is in German (Annalen der Physik, 1904). 

Can someone point me to an English language reference for the analytical derivation of displacement and stress fields in the interior of the specimen ?

IOSO vs Genetic Algorithm (comparison on practical optimization problem)

Submitted by IOSOnier on

Dear Colleagues,



Here we would like to offer you the summary from a published work concernign the optimization of industrial object. The work describes the application of parallel IOSO algorithms and parallel genetic algorithm PGA for the solution of optimization of 3D serpentine cooling passage inside a turbine blade.

 

 

 

cauchy stress, first piola kirchoff stress, second piola kirchof stress

Submitted by bruno-page on

Some basic questions involving cauchy stress, first piola kirchof stress and second piola kirchof stress:

1) We know that Cauchy stress involved deformed areas-therefore this (Cauchy stress) has an obvious physical interpretation

2)Now, first piola kirchof stress is expressed as:

S = JF^-1 . sigma

where, J is the jacobian of the deformation gradient which physically is the measure of the volume change produced by a deformation.

F is the deformation gradient

sigma is Cauchy stress.

Principle of virtual work and conservation of linear momentum

Submitted by bruno-page on

I've been reading Prof.Bower's text on solid mechanics:

http://solidmechanics.org/text/Chapter2_4/Chapter2_4.htm#Sect2_4_1

 

Can anyone plz help me to understand how principle of virtual work is another form of conservation of linear momentum?
