For my
graduation project I’m working on a model to describe cracking behavior. For
this model I want to model a fibre-epoxy interface, see the attached figure 1
(due to symmetry only a quarter is modeled). The fibre part is modeled with
lineair elastic material. The epoxy part is modeled with CPS4 elements, with
elastic behavior and MAXPS damage (damaged evolution included). The connection
between the fibre and epoxy interface can be modeled with both a cohesive
surface and cohesive elements. However

Hi!

My name is Christian and Im having big problems whit geting my cohesive elements to break. I have been stuck for some time now and cant find the right help. Im not experienced whit abaqus so its probably a very simple fault but I cant find it.

crystallography

Does anyone know of a good source for free science and engineering illustrations? I'm particularly interested in crystallography, crystal defects/dislocations, and mechanical properties illustrations.

Thanks

These notes are part of a course on advanced elasticity. The notes recall several phenomena where both elasticity and surface energy are significant, including

Griffith crack
Adhesion of flexible structures
Wafer bonding
Contraction of a soft elastic sheet

The notes also contain a formulation of combined surface energy and elasticity of finite deformation.

Would you like to recommend some ebooks on computational nonlinearity?

ABAQUS

computational nolinearity

Hi, everyone:

I'm recently very interested in computational nolinearity. Would you like recommend some monographs on the computation nonlinearity so that i can have a better understanding of the mechanism of ABAQUS.

Thanks

continuum mechanics

I recent read the book of Prof. J. Tinsley Oden "A short course on nonlinear continuum mechanics"

http://users.ices.utexas.edu/~arbogast/cam397/oden0908.pdf

which declares that reference configuration is an open, bounded, connected subset of R3 with a smooth boundary (in Page 1).

It is strange to me beacause that means we cannot consider the boundary of the deformable bodies in its following discussion.

damage plasticity

hi i am new to abaqus software. i am doing research on failure analysis of composite material. i want to model the workpiece and machine by a tool. any one can please help me if you have any tutorial to model this explicit analysis. i want to analyse the chip also.

please send the help link to stkrajan [at] gmail.com (stkrajan[at]gmail[dot]com)

thankyou

with regards
