using cohesive zone models to study the initiation and the propagation of cracks in a welded structures

Submitted by A.Brick Chaouche on Thu, 03/15/2012 - 13:01

Good mounring, i have a question, i want to investigate the initiation and the ptopagation of cracks near a welding, or within the diffrent zones near it, my question is:

1. Is it permisseble to use the cohesive models to study this kind of fracture problems

2. If the answer is yes, what are the parameters and the measures to take in order to well use them.

2. Is there any previous studies in this field, and can you cite some articles.

Thanks very much.

ABAQUS/CAE

VUHARD

HI,

I am trying to simulate the behavior plastice a sheet metal in ABAQUS using VUHARD but I do not know how I should do. If one of you has used VUHARD in ABAQUS, please help me by sending me to use your *. inp file and VUHARD so I can understand how it works.

Thank you for your help

Hello all, I am having problem with one of our lens doublets getting decemented. we have been cementing this lens for many years and we did not do anything different. Recentely we start seeing this lens decementing. we use NO61 and NO65 (UV curing). Any help of how to prevent this problem from happening again will be very much appreciated.

Thank you,
