hi every body:

What's your idea?  The virtual displacement is special case of hamilton's principle or the hamilton's principle come from virtual displacement?  Or, Which is older?

hello Dear friend

We are glad to announce the 2014 version of the course:

NONLINEAR COMPUTATIONAL SOLID & STRUCTURAL MECHANICS. Theoretical formulations, technologies and computations. Pavia, May 5-9, 2014

Applications are invited for one postdoctoral position in Experimental
Granular Physics with the Collective Interactions Unit at the Okinawa
Institute of Science and Technology (OIST). Our group is broadly
interested in experimental softmatter physics, continuum mechanics, and
applied mathematics, and their application to biologically inspired
questions. Our current emphasis is on interfacial fluid dynamics,
disordered granular solids, and biomechanics of the human foot. For

 I tried to solve the problem
that a rigid disc under harmonic moments resting on a porous half-space, the
porous medium is modeled using Biot's theory, when I consider the disc as
totally impervious, I found from the numerical results that negative damping
appears when the permeability of the porous medium is very low at a small
exciting frequency. I have no idea whether this is possible, can someone give
me some suggestions? Thanks very much.  

I am trying to model the soil churning action of a rotary tiller trough soil structure interaction. Based on some published articles, DEM and SPH approach both have been used to model the tool interaction with the soil. I am little confused in the selection of the appraoch. Can somebody throw some light on advantages and disadvantages of one approach over another and which approach should be chosen for more realistic results.

Our Mechanics of Materials Group at Eindhoven University of Technology, the Netherlands has two openings for talented PhD students in the field of multiscale mechanics of materials. They are part of a European Union funded project on multiscale methods for advanced materials. One opening is on the development of a fundamentally new multiscale approach towards material modelling and the other aims to integrate this approach with experimental methods.

The Nanomechanics Simulations Laboratory at the Mechanical
Engineering Department, Technion, Israel, is recruiting Postdoctoral
researchers and/or PhD candidates in the area of modeling the plastic deformation of metallic specimens at the nanoscale.
The research involves performing simulations at various scales
(Molecular Dynamics, Dislocation Dynamics and Finite Elements Analysis).
We are looking for highly motivated applicants, who are familiar with
modeling mechanical properties. Applicants with a strong background in
