Different Cohesive Section

Submitted by bornvirgo85 on Wed, 04/07/2010 - 17:21

Hello Everyone,

I am modeling cohesive layer(defined as a part) resting on a rigid body. I am trying to give different cohesive properties to the same cohesive layer. So I created 6 cohesive sections by partition. 3 sections have one cohesive property and the other 3 section have the second cohesive property. I have assigned sections through Abaqus/CAE. During the data check itself the job terminates with an error

ABAQUS/CAE

Roll forming

Hi all.

Nice to meet you

I have the report on simulation Roll forming process by ABAQUS.

Wish that I can have your valuable comments

Have a nice and happy day

Buckling analysis using ansys

Submitted by Ajeesh on Mon, 04/05/2010 - 06:33

Hai all, I am performing shear buckling analysis of plate girdersusing ansys. The ultimate shear buckling strength can be easily obtained by applying concentrated load on the model. My issue is to obtain critical shear buckling strength accurately. Some tutorials tell that critical buckling can be obtained from the load - deflection curve where large deformation is initiated.How can i track values exactly. I there any alternative method to track critical buckling.If anyone finds a solution, please reply......

A Conformal, Bio-Interfaced Class of Silicon Electronics for Mapping Cardiac Electrophysiology

Submitted by Jianliang Xiao on Fri, 04/02/2010 - 22:28

In this paper recently feature on the cover of Science Translational Medicine, we report the development of a class of mechanically flexible silicon electronics for multiplexed measurement of signals in an intimate, conformal integrated mode on the dynamic, three-dimensional surfaces of soft tissues in the human body. Mechanics model shows that the strain in the fragile materials, e.g.

define water in abaqus

hallo all

i am new to abaqus and i have a problem

i am designing a pool with water in it.

and i dont know how to define the water as a material in abaqus

so that they will act like water on a dynamic analysys that i plan to do in the future

please help

i spent a days triyng to model the water

Mechanical Properties of Silicon Nanowires

Submitted by Yong Zhu on Wed, 03/31/2010 - 05:27

In this paper that was published a few months ago, we reported the size effects on the elastic modulus and fracture strength of silicon nanowires. In addition, we observed that the silicon nanowires are linear elastic until fracture with a very large fracture strain up to 12%.
