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

Submitted by arash_yavari on

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.

Jacobian matrix of Mooney-Rivlin model

Hi,

does anyone know where I can find the analytical expressions for the components

of the Jacobian matrix of the Mooney-Rivlin model.

I know the compact form of the matrix, with the tensor products, deviators etc,

but I'm looking for the explicit expressions of each component of the matrix.

 

many thanks!

 

 

 

Nonlinear free and forced vibration analysis of a single-walled carbon nanotube using shell model

In this Paper, the nonlinear free and force vibration of a single-walled carbon nanotube (SWCNT) with simply supported ends is
investigated based on von Karman’s geometric nonlinearity. The SWCNT described as an individual shell and the Donnell’s
equations of cylindrical shells are used to obtain the governing equations. The Galerkin's procedure is used to discretized partial

Postdoctoral position in mechanical and material engineering

Submitted by gayoub on

My name is Georges Ayoub; I am looking for a postdoctoral research position in mechanical and material engineering in the field of the polymer science, polymer behaviour and fatigue.

I defended my PHD at the beginning of this academic year (2010/2011). I am very motivated to start a Postdoctoral position, at the end of my thesis, in an Anglo-Saxon country.
