Tensile stresses in an elastic body accelerated by an attractive body force

Submitted by Jayadeep U. B. on

Dear all,

Can someone suggest me literature where the problem "tensile stresses developed in an elastic body accelerated by an attractive body force" is discussed.  The situation is similar to finding the stresses developed in a celestial body falling into black hole (though my interest is in impact with adhesive forces).

The problem is about solving the inhomogeneous wave equation, where inhomogeneous part is due to the attractive force.  So any helpful hints in that direction will also be useful.

Journal of the Mechanical Behavior of Biomedical Materials now accepts MATLAB figure files

Submitted by Laure Ballu on

You can enrich your online articles by providing supplementary MATLAB figure files with the .FIG file extension. These files will be visualized using an interactive viewer that allows readers to explore your figures within the context of the article. The FIG files can be uploaded in our online submission system, and will also be available for downloading from your online article on SciVerse ScienceDirect.

Run ABAQUS subroutines written in Fortran

Submitted by Jingwen Zhang on

Dear colleagues,

 I am a beginner in using ABAQUS subroutines, and currently come into the problem of running ABAQUS subroutines written in Fortran.

I have installed ABAQUS 6.11-1, Microsoft Visual Studio 2010, and Intel Visual Fortran Studio XE 2011 on my computer. However, when I run the test codes, there are the following errors:

Brittle cracking in brittle materials

Submitted by surot on

Hi there,

 I am trying to simulate a crack opening process in ABAQUS. I start up from a simple model of plate with a notch subjected to tension. I would like to see the crack opening. To model a brittle mnaterial behaviour I have added a brittle cracking with sub-option brttle failure and brittle shear.
