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.
High Performance Computing MSc+Ph.D. position available at the University of Glasgow on Massively Parallel Brain Surgery Simulation with the extended finite element method (XFEM and FleXFEM) (University of Glasgow) -- funding body is EPSRC.
One year MSc in HPC in Edinburgh (all costs covered by funding) + 3 year Ph.D. and access to HecToR, one of the world's largest super-computer, including training with experts in massively parallel simulation (10,000+ processors).
The Computational Science and Engineering Program at the University of Illinois at Urbana-Champaign is seeking highly qualified candidates for one post-doctoral research associate position in the Center for Simulation of Advanced Rockets.
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.
A post-doc position on multiscale simulation of cell contact and adhesion shall be available this coming Fall at UC Berkeley. We are seeking for a person who has experience and background on finite element computations, especially in cell contact/adhesion modeling and simulation or finite deformation simulations.
Anyone who is interested in the position please send an email, resume, and reference to li [at] ce.berkeley.edu (li[at]ce[dot]berkeley[dot]edu)
The Australian Mineral Science Research Institute (AMSRI) is a consortium of Australia's best scientists working in minerals industry-related fields. Research activities span the breadth of minerals processing, with major themes of the research being energy efficiency, frugal water use and efficient management of waste. The Mathematics program of AMSRI performs modelling and analysis research across multiple minerals processing areas, including comminution, flotation and waste treatment.
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
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.
