Faculty Position in Mechanical Engineering at University of Chile

Dear all,

In the Department of Mechanical Engineering, Faculty of Physical and Mathematical Sciences, at University of Chile, we are seeking to fill a faculty position with an exceptional researcher in areas related to Mechanical Engineering. The official call is expected to appear by March 2015.

A numerical study of elastic bodies that are described by constitutive equations that exhibit limited strains

Recently, a very general and novel class of implicit bodies has been developed to describe the elastic response of solids. It contains as a special subclass the classical Cauchy and Green elastic bodies. Within the class of such bodies, one can obtain through a rigorous approximation, constitutive relations for the linearized strain as a nonlinear function of the stress. Such an approximation is not possible within classical theories of Cauchy and Green elasticity, where the process of linearization will only lead to the classical linearized elastic body.

Near-incompressible analysis

Hello all,

I am studying some simple finite elements for 2d near-incompressible analysis. Particularly, I am interested in the MINI element. It is basically a 3-node triangle element with nodal pressure and displacement degree of freedoms enriched by a bubble function. Could someone that has some experience with these elements point me out about advantages and drawbacks of using these type of elements?

Thanks,

Alejandro.

Compiling and Building TAUCS a library of sparse linear solvers

I would like to share the following information to all the iMechanica users interested in using TAUCS a library of sparse linear solvers. TAUCS is among the most used libraries of sparse linear solvers and, to my knowledge, its closest equivalent library is SuperLU. For your reference, TAUCS is used in the commercial software Mathematica by Wolfram Research. Its source code can be downloaded from
