Royalty Free Illustrations

Submitted by CS DeFrance on Sun, 02/03/2013 - 21:49

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

Elastocapillarity

Submitted by Zhigang Suo on Sun, 02/03/2013 - 18:57

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.

Compatibility Equations of Nonlinear Elasticity for Non-Simply-Connected Bodies

Compatibility equations

non-sinply-connected bodies

Compatibility equations of elasticity are almost 150 years old. Interestingly they do not seem to have been rigorously studied for non-simply-connected bodies to this date. In this paper we derive necessary and sufficient compatibility equations of nonlinear elasticity for arbitrary non-simply-connected bodies when the ambient space is Euclidean. For a non-simply-connected body, a measure of strain may not be compatible even if the standard compatibility equations ("bulk" compatibility equations) are satisfied.

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

Hello,

I am working in a fluid mechanics theme. Do anybody now something about the Radial Reynolds Number?

Thank you.
