Looking for a postdoctoral position

Dear iMechanica members,

I am looking for a postdoctoral position to work in an experimental lab mainly focused on fuctional polymer material (like- hydrogels, composities etc.) synthesis.

Currently, I am working as as postdoc at UNC-CH to reveal the physical properties of living polymer material mucins/mucs.

I have completed successfully my PhD from the University of Hokkaido, Japan under the supervision of Professor JP Gong.

Questions about stresses distribution in pin-loaded orthotropic plates

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].

could someone tell what should I do to run Abaqus job in High Performance Computing (HPC) systems?

I want to run a job file with Abaqus 6.14-1 Software in HPC system but we did not install Abaqus in our cluster before and I do not know how can I sure about the proper installation. I prefer to run Abaqus graphically but if it is not able, we can do it by .inp file.

the system is CentOs 6.5, 60 node that every node has 4 cpus and every cpu has 4 Gb RAM.I search in the internet but I can not find a step by step guide that explain the procedure of parallelization. 

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?

In SPH method, does it need fracture criterion?

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.

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.
