thermal loading on soil sample

Submitted by miladbabaei on Thu, 04/30/2015 - 19:41

HI all,

im a new user of abaqus (cae,6.10) wanna simulate a thermal loading (heat transfer)on a soil sample?was wondeeing anyone can help me out? top and bottom boundaries have initial constant temp,the sides are adiabatic (is it by default for temp.boundary??)boundary ,in step one ,need to apply steady state heat in order to obtain the temp, distribution in soil sample.

after predefining thermal boundary and creating step for steady state heat and run the job i cannt get any result??i set the output too,i know thats a very vast question, please help me out

Element delatation for Severe Plastic Deformation (SPD) process

Submitted by Dincoz on Thu, 04/30/2015 - 14:48

software

Dear all,

I am using Abaqus/explicite. My material definition is elasto plastic with stress strain values up to strain of 15!. After borthering tries now I think if I can set "Shear Failure Criteria Element Deletation option", it is possible to avoid this error. But I cannot find this option. Could someone guide me what exactly should I do in order to add distorted element deletation option and how? (an step-by-step tutorial will be approciate)

Calculating effective material properties from 3D images: new solutions

Submitted by Simpleware on Thu, 04/30/2015 - 09:20

Researchers and analysts working with 3D image data (CT, micro-CT, FIB-SEM…) of complex materials face a number of challenges when attempting to reconstruct and obtain information from scans. One particular challenge involves being able to compute material properties (such as solid, flow and electrical properties) from scanned samples without having to use significant computational resources, or without combining multiple types of software.

Amorphous intergranular films as toughening structural features

Submitted by Zhiliang Pan on Wed, 04/29/2015 - 23:12

research

The ability of amorphous intergranular films to mitigate damage formation at grain boundaries is studied with molecular dynamics simulations. We find that such films can alter both crack nucleation and crack growth rates by efficiently absorbing dislocations, with thicker films being more effective sinks.

my abaqus simulation of time of flight diffraction technique not differentiating diaffracted wave and lateral wave.both gives same amplitude.what to do to gett a better result?.I am doing my work based on "shear wave TOFD by baskaran".any suggestion?
