Damage model for soft polymer
Hi all,
I'm working on modelling of adhesive joint using soft polymer adhesive types.
Can anyone suggest what are suitable damage mnodel for soft polymer.
I'm using Abaqus FE software version 6.12

Probing the intermediate states between rolling-up and wrinkling thin films
Self-positioned nanomembranes such as rolled-up tubes and wrinkled thin films have been potential systems for a variety of applications and basic studies on elastic properties of nanometer-thick systems. Although there is a clear driving force towards elastic energy minimization in each system, the exploration of intermediate states where specific characteristics could be chosen by a slight modification of a processing parameter had not been experimentally realized.
In SPH method, does it need fracture criterion?
In abaqus , there is an example for SPH. It can be obtained by:
abaqus fetch job=ver_prc_projectileimpact.inp
There are two fracute criterion in this file.
But even both of them are removed, the simulation results are similar.
Why?

Is anyone familiar with the use of yield strength in creep zone?
I was going through some literature on AUSC steam turbine (operating temperature 700 deg C). In many of the papers i have seen that 400 MPa yield strength at operating temperature was used as material selection criteria for turbine rotor. At the same time some people are using Alloy 617 for same application, for which creep rupture is quite high (around 137MPa at 700 deg C) at operating temperature but yield strength is around 200 MPa.
Two Ph.D. positions available at University of Houston
Two Ph.D. positions in the general area of mechanics are currently available in the Department of Civil and Environmental Engineering at University of Houston.
Applicants should possess an MS degree in civil, mechanical, or other related engineering field at the time of enrollment at University of Houston. A strong background in continuum mechanics is required.

Dear colleagues,
I invite you to submit an abstract to the following minisymposium: Modeling and Characterization of Nanocomposites and Molecular Heterostructures as part of the Engineering Mechanics Institute annual conference at Stanford University.

ANSA or Hypermesh
Hi all
I am using Hypermesh for modelling a simulation model for automtorive structure.
But I dont understand which is better for my usage.
I need to make 1.Geometry cleanup 2.Mesh (2D & 3D) 3.also setup for some type of analysis (ex: strength,Crash)
Which will be beter for above operations.
thermal analysis of welding.
Hiii....................!!!!!!
I am doing my M.tech thesis in finite element analysis of butt welding process. please suggest me which is easier to use ANSY or ABAQUS, As it dealt with moving heat source and other mechanical model.
Abaqus Standard/CFD
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.
Survey of Computing Platforms for Engineering Simulation
How many organisations are using Cloud Computing? Is the use of High Performance Technical Computing in engineering simulation set to grow in the next 5 years? Will Tablet PCs be powerful enough to run my application? What do my peers think?
These are typical questions asked by the engineering simulation community. Wouldn't it be great if we could take a snapshot of the type of computing platform we're using today and also predict where we will be in the next 5 years?
