Question about calling subroutine to get strain and stress

Submitted by zengziw on

I am writing a subroutine DFLUX, the FLUX(1) is dependent on strain and stress. But I don't know how to get the strain and stress. I use SPRINC in the code but it seems to be wrong.

The equation for the problem is 

q=(α^2XΩXε^2XE)/2
E=(σ/ε)*sin(d)
σ is stress and ε is strain

Postdoctoral position on: Identification of elastic microstructures from full-field measurements - CNRS & Aix-Marseille University France

Submitted by Cédric Bellis on

A one-year postdoctoral position is available at the Laboratory of Mechanics & Acoustics, CNRS & Aix-Marseille University, France.

The project focuses on image-based identification problems for physical quantities of interest in solid mechanics within the framework of optical measurement methods for complex manufactured materials. The guideline objective is to develop an identification framework for multiscale, heterogeneous and anisotropic media.

More information can be found in the attachment.

Application deadline: February 28th, 2015.

PREDICTION FOR DEFORMED PART WITH TIME

Submitted by albanna on

Dear ALL,

Does anyone here has an experience carry out  FE analysis for a part[bracket] which was deformed plastically during cyclic loading test.

I'm now working to resolve this issue when a bracket was fail to withstand the constant loading of 500N during cyclic test. It was reported fail at ~3800 cycles which was less than target.

Micromechanics Simulation Challenge - Level 1

Submitted by Wenbin Yu on

For the purpose of establishing the best practice for homogenization and dehomogenization needed in composites design and manufacturing, cdmHUB launches the Micromechanics Simulation Challenge. After incoporating comments from  academia, industry and commercial software providers, we have finalized the final draft for Level 1 problems, which is attached here with more details can be at https://cdmhub.org/resources/665.

Concrete block under thermal load

Submitted by apurv_vaidya on

Dear all,

I am new to abaqus and trying to analyze the thermal analysis on a concrete block of size 0.15 x 0.15 x 0.15.

The surface heat flux of magnitude 100 that I am giving is only from one side and NOT having any boundary conditions.

If I choose steady state condition then I get an error as "Time increment required is less than the minimum specified".

Also I cannot define time period. I want the nodal temperature of concrete subjected to thermal load from one side for 24 hours of heating at 100oC.

Please help!
