Dear Colleagues,

The interaction between cars or trains and bridges has been often described by means of a simplified model consisting of a beam loaded by a traveling mass, or by a traveling oscillator.Among others, two aspects are essential when dealing with masses traveling along flexible vibrating supports: (i) a complete relative kinematics; and (ii) a continuous transition between a traveling mass, rigidly coupled, and a traveling oscillator, elastically coupled with the support.

Traditionally, the deadline for ASME AMD awards nominations has been the 5th of November. However, starting from this year, the AMD executive committee instituted the new deadline of October 1st (see the earlier announcement here). This was done to allow the various awards committee members adequate time to review the growing number of nomination well before the IMECE annual conference.

Eigenstrains in nonlinear elastic solids are created through defects, growth, or other anelastic effects. These eigenstrains are known to be important as they can generate residual stresses and alter the overall response of the solid. Here, we study the residual stress fields generated by finite torsional or shear eigenstrains. This problem is addressed by considering a cylindrical bar made of an incompressible isotropic solid with an axisymmetric distribution of shear eigenstrains.

Postdoctoral position is open at the "Technologie des Polymères et Composites & Ingénierie Mécanique" (MINES-Douai, France). This project is a part of the European project JOIN'EM. Candidate is expected to conduct enriched FEM simulation and should have strong background in the mechanics of composites (multi-scale modelling and fatigue damage). The following experience is expected from the candidate, i.e. coding and/or scripting, fatigue damage simulation and material model development (ABAQUS/UMAT). 

Cracks typically follow paths that locally give a mode I crack tip load. At mixed modes crack are extended via a kink in a direction that locally restores mode I. In isotropic materials this is known to more or less, true for static and dynamic loads. Exceptions are cracks that are subjected to high compressive load, e.g., at contact between train wheels and rails or at cracks caused by seismic movements. Other exceptions are cracks growing in anisotropic materials, at grain boundaries or other weak, or by deformation weakened, interfaces.
