Hi everyone,
I am not a student majoring in the mechanics. But I have found that: the element eroding method is so powerful in numerical simulation (i.e. using ls-dyna) if we reduce the mesh size, then we can get a very perfect fracture process of material. So why we need fracutre mechanics?
a good reference for discrete element method
Dear friends
I am using ABAQUS for thermal analysis using laser moving heat source. I have successfully implemented DFLUX for thermal and subsequent stress analyses. My question is: How can I progressively delete (during moving heat source) those elements in transient thermal analysis whose temperature is above melting temperature? My intention is to analyse their effect on stress fields in subsequent coupled stress analysis.

Dear All
I want to knnow what is the Strain VAlues at the SA-387(or 11/4 Cr 1/2 Mo Ni Si) plate at 940'F and in creep RAnge at time of 1000000 Hrs of loading...how to find Strain Values at SAme TEmp & Time and Diff loading of mtrls like 10,100, 1000 and So on..
Please Help...

The newly founded National Hypersonic Science Center -- Materials and Structures is to organize a minisymposium in this year's WCCM (2010) on VirtualTesting for Hybrid Hierarchical Materials for High TemperatureApplications. Please see the attachment for paper solicitation. We will greatly appreciate your consideration of submitting a paper to our symposium (minisymposium No. MS5041)
Welcome to the January 2010 issue! In the issue of May 2007 , Prof. Xiaodong Li outlined the existing experimental methods for mechanical characterization of 1D nanostructures. In this issue, I will discuss along the same line but focus on experimental methods enabled by microelectromechanical systems (MEMS).
Happy New Year to all the members of the iMechanica family.
