PhD position : hex mesh generation

Submitted by remacle on

Two PhD studentships opportunities are available at the Universite catholique de
Louvain in Belgium for outstanding candidates.
The aim of the project is to develop a novel approach for generating
dominant hex meshes for general/complex 3D models. The approach will be based
both a generalisation of Lloyd's algorithm and on the resolution of some kind of
PDE in the domain in order to compute distances, curvatures, surface
geodesics... We look here for an indirect approach i.e. we first generate the
points and then reconnect them. All the developments will be done in the
framework of gmsh (http://www.geuz.org/gmsh).
Successfull candidates should have a strong background in applied
mathematics/numerical methods for CFD. Some knownledge of mesh generation

Alternate expressions for the near-tip in-plane mixed-mode K-field stresses and displacements

Submitted by Dhirendra Kubair on

Alternate expressions for the angular variation of the K-field stresses and displacements around a sharp-crack embedded in an elastic medium subjected to an in-plane mixed-mode (mode-1 and -2) loading are presented. The expressions are derived in terms of the mode-mixity angle instead of superposing the pure-mode fields. The alternate expressions are derived using complex potentials and the Kolosov-Muskhelishvili method. The mixed-mode stress and displacement fields are presented in the crack-tip Cartesian and polar coordinates. We have obtained the crack growth angle in terms of the mixity-angle assuming the maximum hoop- and principal-stress criterions.

 

buckling analysis for cylindrical ring

Submitted by shmuel.baskin on

Dear Members Hello

 

I am conducting buckling analysis for cylindrical ring (Short and thick cylinder) with Lateral Pressure.

 

I reviewed the basic books ("Buckling of Bars, Plates, and Shells" and "Theory of Elastic Stability" – Timoshenko) and all I could find is buckling of rectangular planes in the axial direction or buckling of cylindrical shells which buckles in the radial direction.
