Progressive Damage Model

Shear Failure

Damage Initiation

Damage Evolution

Hi,

I want to try abaqus progressive damage model to simulate steel failure in Abaqus. I read the manual, and found that progressive damage model would be sufficient for my purpose. As I am quite new to damage modeling, I do not know how to determine parameters for shear failure or ductile failure or jjohnson cook model. Also, I would like to use damage evolution as well. Could anyone suggest me some typical parameters for steel (both damage initiation and damage evolution).

Thanks.

Regarding Journals and the Review Process

technical journals

reviews

I thought it might be useful to the iMechanica community to write something about the review process in scientific journals. For full disclosure, I am one of the co-editors of the Elsevier journal Finite Elements in Analysis and Design. Indeed, it is precisely that editorship which informs the content of this blog post.

Guidance about job opportunities in Cellularmechanics or BioMechanics

I will be very grateful if anybody please guide me about the job opportunities after PhD studies in cellular mechanics in Europe or Asia. My PhD topic is Comptational simulation of mechanical tests with isolated animal cells.

retirement age or discrimination? Nature speaks of "sticking" around, but in europe we have new laws

retirement

In January 2011, the UK government announced its intention to stop
compulsory retirement for people aged 65, despite criticism of the move
by employers’ groups. Campaigners against age discrimination and unions
welcomed the change. However, official guidance makes it clear that
employers will be able to dimiss staff no longer capable of carrying out
their work. Official figures show more than two thirds of British
employers have already eliminated fixed retirement ages.

Lens cement failure

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,

Multiscale simulation

multiscale simulation

Nowadays, we are talking about multiscale simulation. I am surprising that we discussed about multiscale modeling while units are still exist. In my point of view, the multiscale only be achieved if units in general equations were treated.
