Post-Doctoral Position in Modeling of Thermal Transport in Crystalline Solids

Submitted by AnterEl-Azab on

The Materials Theory Group at the School of Materials Engineering of Purdue University has a post-doctoral opening in the area of modeling of thermal transport in crystalline solids. The postdoc will use Boltzmann Transport Equation approach to investigate the phonon and electron thermal transport in crystalline solids with defects. Applicants with closely related theory background in physics, materials science, mechanical engineering, or other majors are encouraged to apply. The ideal candidate is one who is strongly interested in the fundamental concepts of thermal transport and related computational modeling, and must have excellent programming skills. To apply, please send a curriculum vita with list of publications and the names and contact information of two references to Professor Anter El-Azab (aelazab [at] purdue.edu). The cover letter should explain the relevance of the applicant background to the postdoc research topic above. This position is part of the DOE funded Energy Frontiers Research Center for Thermal Energy Transport under Irradiation (TETI), and the postdoc is expected to collaborate with a large team of theorists and experimentalists. The position is available now and will remain open until filled.

Recent advances in soft materials

Submitted by Zhigang Suo on

I attach the slides of my talks at last week’s MRS meeting in Boston on two topics:

  • Fatigue-resistant stretchable materials

  • Integrated soft materials

Advances on these topics made by several groups break grounds and likely reach far.  The available time limited my talks to recent works of my own group and collaborators. The slides may serve as a graphical reminder of papers to check out. Several recent reviews may help to connect to broad literature.

Plane stress Abaqus UMAT

Hello everyone,

I have created a UMAT code for J2 elasto-plasticity with isotropic hardening for 3D solid elements.

At this point I would like to support also plane stress shell elements. What changes in the code are

suggested? The already implemented code, takes as input the strain tensor at time tn and the strain

increment tensor and updates the stress at time tn+1 and calculates the material Jacobian and 

achieve quadratic convergence. The stress and strain tensors are manipulated as 6x1 vectors and the 

Abaqus Explicit: difference in TEMP, STRESS and PEEQ computation between adiabatic and coupled

Submitted by Olivier Pantalé on

Hi,

I have the two following INP files for Abaqus where the only difference is that in one case I'm using a CAX4R element on the other case, I'm using a CAX4RT element. Solver has been changed from one case to the other one.
This is the only difference between both cases.

Simulation time is small, so that conduction is negligible.

BUT: results in terms of Strains, Stresses and Temperatures differs.
T = 164.1°C for CX4R
T = 323.9°C for CAX4RT

The difference is Huge, what's Wrong ?
