Abaqus/CAE version 6.6

Submitted by Pascal Yee on

 Dear all,

For my final year project, I've done the 3D model of a test fixture which is used for the compression testing of a specimen.

When I apply a downward vertical displacement to top Slider B, eventually the 2-slider linkage mechanism will cause the bottom Slider A to move horizontally and to compress the cube shaped specimen.

 

Differences between cohesive/interface/embedded process zone

Submitted by David MORIN on

I am PhD student and i'm working on the behavior of bonded joints under impact and i have one question :What are the differences between a cohesive element, an interface element and a embedded process zone element ?  Do they have fundamental differences or it's only a difference of the cohesive law expression.

1. Central crack loaded with stress.

(A) The stress intensity factor for a central line crack in an infinite plate is found to be  

 K=p(πa)^.5

 

where p is the pressure exerted along the crack line. (A) Does this formula imply a stable or an unstable crack propagation when p reaches the critical stress level? (B)  Present an experiment to support your answer in (A). Specify your experiment in details.

New (Free!) Solid Mechanics Textbook

Submitted by Allan F Bower on

I have posted an advanced solid mechanics textbook on http://solidmechanics.org/

It works on Internet Explorer, but may not work on all browsers. Topics include: mathematical descriptions of deformation and forces in solids; constitutive laws; analytical techniques and solutions to linear elastic and elastic-plastic boundary value problems; the use and implementation of FEA; fracture mechanics; and the theory of deformable rods, plates and shells.

How do we use Abaqus to simulate the orthogonal metal cutting process and check for values of various parameters during the cutting operations ? I would be extremely thankful to anybody who could assist me on this . Tahnking You in Advance ,
