Harmonic Analysis using LMM

Submitted by vj_sen on

I am working in ANSYS multiphysics for vibration analysis of electronic equipments. To find out absolute displacement on cards in Harmonic Analysis by using Large Mass Method, I need to give 1g acceleration on Large Mass. I am applying (Large Mass*9.81*1) force on Large Mass so as to simulate 1g accleration but response at same LM location after analysis is coming 2.5g. Can anybody suggest any alternate method of doing it?

We have manufactured stretchable thin-film transistors and interconnects directly onto an engineered silicone matrix with localized and graded mechanical compliance. The fabrication only involves planar and standard processing. Brittle active device materials are patterned on non

Viscoplasticity (Anand's Model in ABAQUS CAE 6.8)

ABAQUS/CAE

Hi,

I am trying to model a double lap shear in ABAQUS. In Abaqus version
6.7 and above, Anand's model can be invoked by editing keywords and
adding necessary data lines  in keyword editor. I am facing some
prblems in running the job analysis and since I am new to working with
ABAQUS, I am not able to solve the problem. The problem is, when I
submit the job the status keeps on showing "Running" without showing
any error or warnings. I have tried all both coarse and finner meshes
so i think there is no problem with convergence. 

Whitesides on how to write a paper to communicate your research

Submitted by Zhigang Suo on

George Whitesides has published over 1,100 papers.  In 2004 he published a three-page essay “Whitesides’ Group:  Writing a Paper”.  I have been asking all my students to study this essay when they begin to work with me.  Now you can watch Whitesides on video explaining his approach to publishing papers.
