Hi

Dear Colleagues,

We recently have reported first measurements of surface stress evolution in a material as a function of uniaxial time dependent deformation and at temperatures upto 100 degree C using a new analytical technology, Nanomechanical Raman Spectroscopy developed in our lab (Interfacial Multiphysics Lab directed by Dr. Vikas Tomar at Purdue).

In particular, we wanted to bring to your attention the following publications:

I just found a utility routine in ABAQUS (GETVRMAVGATNODE) functioned to obtain contact information (e.g. contact pressure) detailed as follows:

<p>Hello guys</p>
<p>I want to increase my accuracy in calculating strain energy for whol model in a simple composite under static load.</p>
<p>please suggest some methods for increasing my accuracy to achieve a dramatically result.</p>
<p>If someone know about this issue please leave your email for sending my file .</p>
<p>Unlucky my file has a giant size and I cant upload it in this part.</p>
<p>please help me</p>

Dear all,

I am now reading a paper about the stress distribution in pin-loaded orthotropic plates.

The paper 'Contact stresses in pin-loaded orthotropic plates' is written by Prof. M.W. Hyer.

In this paper, the stresses on the boundary of the hole in the plate are given by a complex Fourier series with unknown coefficietns Ak. The unknown coefficients Ak's are determined by a system of algebraic equations: [C]*{A}={B}. A collocation procedure is needed to construct the square matrix [C].

Hi, I'm trying to solve a problem with heat transfer and fluid. When I co-execute heat transfer model and CFD model, the following error is encountered "An unrecoverable error has been encountered with the co-simulation engine".

Can anyone help me solving this error?

Gratefull for your attention.
