Max penetration error in ABAQUS

I am doing contact simulation of soft material. I want to change the default criterion for max penetration error, but can't seem to find how to do it. I tried contact controls relative and absolute penetration tolerances, hcrit but that did not affect the error criterion. Can someone help me please?

Seeking a postdoctoral position

I was awarded my PhD in Structures and Materials Mechanics from Ecole Nationale des Ponts et Chaussées (France). My thesis focused on the nonlinear  dynamics of cracked turbines rotors (please see attached abstract) and was done at the Mechanical Solids Laboratory of Ecole Polytechnique. The Thesis (in french) could be downloaded at http://pastel.paristech.org/1793/.


Time dependent vs Independent

In Computational mechanics, for rate(time) dependent calculations (eg. Creep, plasticity), when we say time step dt, does it mean physical time.

Can I think this way:

I start at time 0 and calculate stress, strain etc  after 1 sec, 2 sec, 3 sec..

Also, what exactly is strain rate? why do some books say ..'when a strain rate is applied'''..I'm confused..dont we just apply displacement or force all the time.

Does it mean that..the expression of strain rate gives how the strain evolves with time...(eg; In creep, under constant load, how the strain evolves with time)

Kindly throw somelight on these..I'm new to computational mechanics..

Localized and extended deformations of elastic shells - Ashkan Vaziri & L. Mahadevan, Early Edition PNAS

The dried raisin, the crushed soda can, and the collapsed bicycle inner tube exemplify the nonlinear mechanical response of naturally curved elastic surfaces with different intrinsic curvatures to a variety of different external loads. To understand the formation and evolution of these features in a minimal setting, we consider a simple assay: the response of curved surfaces to point indentation.

Ph.D. Research Assistantship in Multi-Scale/Multi-Physics Material Modeling at the University of Colorado, Boulder

A graduate student researcher is sought to work on a theoretical and computational aspect of multiscale/ multi-physics material modeling (with an emphasis on biological materials and structures). The project’s envisioned outcome is to a better understanding of the relationship between the small scale physics and structures and the overall macroscopic properties of a material. This research has application in the design of new, smart material, or in the development of treatment for injuries and disease of biological tissues.

We have an immediate opening in the Department of Engineering Science and Mechanics for a postdoctoral research associate in multiscale modeling and computational mechanics. The focus of this position is on the modeling, simulation, and analysis of the nonlinear evolution of coupled macro/microstructure in failure processes, with an emphasis toward structural health monitoring. Coupled-field models using continuum damage variables will be used to study the fundamental spatiotemporal features of damage evolution, particularly regarding the nature and origin of unpredictability in damage processes. The candidate must have a solid general background in theoretical mechanics and dynamics, and be familiar with nonlinear finite element analysis

The factory idiom and material models

I'm leaving the US in a couple of days and will probably take a hiatus of a few months from iMechanica.  Before I leave, I want to tell you about a C++ idiom that eases the implementation and use of multiple material models in a computational mechanics code.

The first book on C++ idioms was by Jim Copilien sometime in the late 1990s called "Advanced C++: Programming Styles and Idioms".  The idea of such idioms has become considerably widespread since then - so much so that there is a Wikibook on the subject .

Cell and Biomolecular Mechanics in silico, Nature Materials, Volume 7, 2008.

Recent developments in computational cell and biomolecular mechanics have provided valuable insights into the mechanical properties of cells, subcellular components and biomolecules, while simultaneously complementing new experimental techniques used for deciphering the structure–function paradigm in living cells. These computational approaches have direct implications in understanding the state of human health and the progress of disease and can therefore aid immensely in the diagnosis and treatment of diseases. We provide an overview of the computational approaches that are currently used in understanding various aspects of cell and bimolecular mechanics.
