Hi everybody,

do you know where I can find some informations about the relation

between particle size and critical normal stress at the interface particle /matrix

for a particle embedded in a matrix?

I read the Chen's article 'Size effect of particles on the damage dissipation in nanocomposites'

but this article deals with spherical particles. I am studying clay/matrix nanocomposites and I would like to

calculate the relation between clay size and debonding stress.

Thanks,

Cecilia

Hi friends:

This is Henry, a graduate student in USA.

I am recently trying to model a 0 thickness cohesive zone with curvature and I realize that by using mesh edit.

When I made it and submit the job, the ABAQUS always told me the node numbering has a problem and thus abort the job.

Does anyone who has experience with that?

Thanks.

Henry.

Hi,



I have developed a 2D transient thermal analysis FE code which doesn't
seem to be correct. I am sure there is a conceptual problem in the
formulation itself which I have not been able to understand and could
not find concrete information in books.



I am putting up the question in a very simplified form so as to address the correctness of the formulation.



Let's say we have a square of unit length with 4 nodes at each corner
(Q4 element). Initial temperatures are specified as 100 for all nodes
