I am runnin simulations for heat transfer analysis counting conduction, when I add the effect of surface radiation to environment with *radiate or *sradiate , I am getting the error message:
***WARNING: Temperature at 1 nodes has fallen below absolute zero. Increment
will be attempted again with a new time increment. The nodes have
been identified in node set WarnNodeTempBelowZeroStep2Inc45.
Using the data from 3D hybrid lattice boltzmann code under parallel environments, some interesting simulated results are obtained by using Tecplot.
Tips:
After download the attached files, please change files name from *.ppt to *.wmv, then they can be display normally by media player
Is there anyone willing to give me the students solution manual for MECHANICS OF COMPOSITE MATERIALS by AUTAR KAW (2nd Ed)
It's urgent. I have exam coming up. Please help.
Arch-shaped microelectromechanical systems (MEMS) have been used as mechanical memories, micro-relays, micro-valves, optical switches, and digital micro-mirrors. A bi-stable structure, such as an arch, is characterized by a multivalued load deflection curve. Here we study the symmetry breaking, the snap-through instability, and the pull-in instability of a bi-stable arch shaped MEMS under static and dynamic electric loads.<!--break--> Unlike a mechanical load, the electric load is a nonlinear function of the a priori unknown deformed shape of the arch.
We are offering a free size-limited version of the ADINA finite element analysis software widely used for solving linear and nonlinear structural, heat transfer, CFD and multiphysics problems.

Soft active materials have received increasing interests recently. Here, soft materials can broadly refer to polymers, elastomers, hydrogel gels. Active materials mean that these materials can respond to external stimuli. Examples of soft active materials include shape memory polymers, environmentally responsive hydrogels, liquid crystal elastomers, etc.
Inspired by recent works by Wei Hong , Xuanhe Zhao, Zhigang Suo, and their coworkers, we started a project on hydrogels, with particular interest in various instability patterns observed in experiments. The attachment is our first manuscript on this subject. Through this work we hope to achieve the following:
A postdoctoral research position in developing first-principles based multiscale modeling of Li ion batteries is available immediately at the Richard G. Lugar Center for Renewable Energy in Indiana University-Purdue University Indianapolis (IUPUI). The candidate will work on a project on developing and applying multiscale simulation approach to modeling the material processes occurring in Li-ion rechargeable batteries. This project involves close collaborations with the experimentalist scientists.
Hello,
I am trying to include a failure criteria for a single yarn in a plain- weave fabric model.The yarns behave as elastic-brittle( That is there is no plastic deformation)
I have the failure stresses and strains data in both fiber and transverse directions.I have included the following properties:
Material definition
Density
Elastic : engineering constants
Viscoelastic: Relaxation test data
