The Summer School on Advances in Finite Element Methods will be held in Cape Town, South Africa, from 14-18 Jan 2013.

The website www.fesummerschool.co.za contains details such as registration, accommodation, lecturers and the schedule. 

The objective of this summer school is first, to provide the necessary background in the mathematics of finite elements, and second, to build on this background by addressing the topics of adaptivity and discontinuous Galerkin methods.

Hi folks !

I have a question which is more mathematical than mechanical. However since it is to solve mechanical problem, one of you may have an answer !

I want to solve a non-linear problem with non-linear equality constrains and I'm using a augmented Lagrangian with a penalty regularization term that, as well known, spoils the condition number of my linearized systems (at each Newton iteration I mean). The bigger the penalty term, the worse the condition number is. Would someone know an efficient way to get rid of this bad conditioning in that specific case ?

Help: calculate elasticity tensor for hyperelastic material with plane stress configuration

Submitted by Haofei Liu on

Ask iMechanica

Dear all,

I am confused with the calculation of elasticity tensor of hyperelastic material in plane stress configuration. Your helps are very much appreciated. Below is my question:

Incompressible strain energy function is expressed as, saying, U=***+p(J-1).

Therefore, the second piola-kirchhoff stress is: S=***+pC^-1 (the Lagrange muliplier p is treated as an arbitrary constant here, right?).

Using the plane stress condition, S<33>=0 so that p is updated as a function of deformation.

The Wyss Institute for Biologically Inspired Engineering and the School
of Engineering and Applied Science at Harvard University invites
applications for immediate openings for a joint postdoctoral fellow
position between the Whitesides Group (Prof. George Whitesides) and the
Harvard Biodesign Lab (Prof. Conor Walsh). The research is expected to
involve material science and mechanics of soft materials with a focus on
developing novel materials (e.g. actively variable stiffness, flexible
composites, etc) and fabrication approaches for the next generation of
