SES Annual Meeting

Dear Colleagues,

The 53rd Annual Technical Meeting of the Society of Engineering Science will be hosted by the University of Maryland (UMD) during 2-5 October 2016 (note the new conference date). As part of this meeting, we are organizing a symposium to address recent experimental, computational, theoretical, and manufacturing advances on the mechanics and physics of soft materials. Topics of particular interest include:

Problem in ANSYS Transient thermal analysis

Submitted by beinghappy1503 on Fri, 04/22/2016 - 05:34

I want to do a transient thermal analysis in butt welded joint.The heat flow I have given 3200 watt(Q = efficiency x current x voltage = 0.8 x 160 amp x 25 volt)to the welding zone, given 20 load step(as welding is completed in 20 sec),convection co-efficient = 11.14, emissivity = .4 and applied both boundary condition convection and radiation on every surface except welding zone. But after solving the minimum temperature of the plate is coming in negative.Can anybody tell me what i am missing?

Constitutive model

Those involved in the modelling of the failure of plain/reinforced concrete using damage and plasticity might be interested in our webpage

http://petergrassl.com/Research/DamagePlasticity/CDPMLSDYNA/index.html

which we have created to support our concrete damage plasticity model CDPM(2) in LS-DYNA. You can find there a number of example input files, reports and our implementation of the model in the form of a user subroutine.
