Hi all!!!

I have a very basic question in Fracture Mechanics. The question is as following.

"Stree Intensity Factor (SIF) is more in plane stress problems (plasic zone size is big) than in plane strain problems (plasic zone size is small). How do we explain this, without refering or invoking energy conecpt?"

I request to give some thoughtful explanation.

With regards,

The ADINA System offers comprehensive capabilities for linear and nonlinear finite element analysis of solids & structures, CFD, fluid-structure interactions, multiphysics, and complete pre- and post-processing with interfaces to various CAD and CAE systems. It also offers user subroutines for material models, elements, loads...

Hello everyone,I am researching the dynamic crack propagation problem using the cohesive element.At this moment, I am using the LS-DYNA (971)software's cohesive material model ,But it does't consider the penetration of bulk elements when the cohesive elements after deleted or not deleted. so the bulk will penetrate each other when under exterior dynamic load. From the literature, I know that many reserachers use the solver which is writern by themselves,and the cohesive element also writen by self. How can some kind expersist give me a tutoial ,Thanks.

Hi all,

Can anyone explain me the characteristic features of continuum mechanics, micromechanics and nanomechanics?  My present level of understanding is:

A Ph.D. Research Assistantship position in multi-scale computational mechanics of fracture of composites (with application on concrete) will be available to start in January 2010 in the Department of Civil Engineering, at the University of Colorado at Boulder, Colorado, USA.

A question has arised when I read a book about fracture mechanics recently.

This question is about the calculation of potential energy in "fixed-grips" (prescribed displacement) and "dead-load" (prescribed displacement).
