Looking for Postdoctoral Position

Submitted by Likun Tan on Thu, 10/02/2014 - 06:08

Dear imechanica members,

My name is Likun and I am posting this blog in searching for postdoctoral positions in Computational Solid Mechanics.

I obtained Ph.D. in Computational Mechanics at Carnegie Mellon University. My thesis work involves developing multiscale method for retrieving slow-time scale behavior from molecular dynamics.

I also have several years' research experience in multiscale analysis and phase-field modeling of hysteresitic behaviror in active materials.

Micromechanics of hierarchical materials: a brief overview

Submitted by Leon Mishnaevsky on Wed, 10/01/2014 - 10:58

research

hierarchical materials; wood; timber; nanocomposites; biomaterials

A short overview of micromechanical models of hierarchical materials (hybrid composites, biomaterials, fractal materials, etc.) is given. Several examples of the modeling of strength and damage in hierarchical materials are summarized, among them, 3D FE model of hybrid composites with nanoengineered matrix, fiber bundle model of UD composites with hierarchically clustered fibers and 3D multilevel model of wood considered as a gradient, cellular material with layered composite cell walls.

Algorithm for Contact Pressure (CPRESS) in ABAQUS

Does anybody know the underlying algorithm for the contact pressure in ABAQUS. Is the contact pressure calculated from the stresses?

Many thanks in advance!

ABAQUS Simple Pull out Test

Submitted by BenWu on Wed, 10/01/2014 - 06:16

Hi,

Model:

I am modeling a simple pull out test, 30 inch diameter by 20 in tall concrete cyclinder, with a 25 inch steel rebar embedded 5 inch into the concrete cylinder. The goal is to see what is the stresses of the embeded region for both the concrete and steel rebar. Ultimately, I would try to incorporate the damage concrete plastic model, but that is after I figure this out.

Constraints:

VUMAT+SHELL+REBAR

Submitted by Massar on Wed, 10/01/2014 - 02:16

I am modelling RCC with a VUMAT. The subroutine is ok with 3D solid, shell or 2D plane stress, but when I use 3D shell and include Rebar it doesn't run.

I can run it with reinforcement in Solid or plane stress element.

Can any one guide me where I am making the mistake.
