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?

melosh competition

The Annual Robert J. Melosh Competition for the Best Student Paper in Finite Element Analysis was held last Friday, April 24, on the campus of Duke University.

The winner of the 2015 Melosh Medal is Maurizio Chiaramonte, from Stanford University, for his paper “The H-Version of the Method of Auxiliary Mapping for Higher Order Solutions of Crack Problems.”

Maurizio was selected as the winner on the basis of both his written paper and his oral presentation. The other finalists at the 2015 competition were:

How to get OP=MOD with Python script in Abaqus?

Submitted by mikechy on Mon, 04/27/2015 - 19:11

I have the fixed boundary conditions in the previous step. In the next step I need to modify BC. For this I use setValuesInStep in Python script, but get OP=NEW instead of OP=MOD, as I want. Any idea how to get the desired OP=MOD by using Python? Thanks in advance.
