Marie Curie Post-Doc position in Computational Thermomechanics at VESUVIUS (Belgium): deadline May 30, 2015

You will be hired for a 24 months assignment starting as soon as possible by

Vesuvius Company (Belgium) on a FP7 Marie Curie-IAPP project, in cooperation with

a very active group in Solid Mechanics at University of Trento.

 

The candidate will implement the constitutive models developed for high- temperature behaviour

of materials in external routines for finite elements computations and tested to judge the

numerical stability and accuracy. The software will be subsequently employed in the design

Discussion of fracture paper #11 - Fracture processes and phase field modelling

In the latest volume of Engineering Fracture Mechanics there is an interesting paper about the calculation of crack growth paths by use of a phase field model. The considered material is inhomogeneous and that causes the crack to follow a winding path through the material. The material structure is from a CT scanned micro-structure of a cement-based porous material. The paper is:

strain energy density fracture criterion

I'm doing my master degree on fracture mechanics
I want to simulate crack propagation direction on the basis of strain energy density fracture criterion (SED) under mixed loading
I'm using abaqus program but i dont know how to do this
so please if you can help me to know if the program can do this and how

Evolution of mixed cementite morphologies during non-cooperative eutectoid transformation in Fe–C steels

We numerically investigate the characteristics of concurrent carbon redistribution pathways, as the ferrite–austenite front evolves during an isothermal eutectoid transformation starting from a random distribution of preexisting cementite particle.

A state of stress is a linear map

A state of stress in a body.  Components of stress.  Subject to a load, a body develops internal forces.  The distribution of the internal forces in the body is usually inhomogeneous. For example, when a rod is bent, part of the rod is in tension, and the other part of the rod is in compression.

If the internal forces are uniformly distributed in the body, the body is said to be in a homogeneous state of stress.  For brevity, we often say a state of stress, or just stress.

Bifurcation Diagrams for the Formation of Wrinkles or Creases in Soft Bilayers

Subject to compression, elastic materials may undergo bifurcation of various kinds. A homogeneous material forms creases, whereas a bilayer consisting of a stiff film and a compliant substrate forms wrinkles. Here, we show several new types of bifurcation behavior for bilayers consisting of films and substrates of comparable elastic moduli. Depending on the ratios of moduli and thicknesses of the two materials, the critical strain for the onset of creases can be either smaller or larger than that for the onset of wrinkles.

Element delatation for Severe Plastic Deformation (SPD) process

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)
