PhD Position: Solid Mechanics/Biomechanics at KTH-Stockholm
A four to five-year PhD position focusing on the analysis of multi-scale phenomena in diseased blood vessels including atherosclerotic plaques has recently been opened at KTH Solid Mechanics. The position is fully supported by the Swedish Research Council.
I am working on crack propagation . I am trying to figure what factors should be taken into account when the crack is being propagated using XFEM.
I am especially interested to know what happens to the additional dof's corresponding to enriched nodes. Once the crack is propagated and crack tip is at new location , we add new dof's corresponding to enrichment functions , but what happens to the information stored by the dof's of previous enriched nodes,do we forget them altotgether , or do we map it to the new enriched nodes?
Hello,
Strain gradient based (non-local) plasticity and damage models have been studied quite extensively in the literature.
I was wondering if anyone has experience in the development of cohesive zone models that obtain the tractions in front of crack tip not only as a function of the diplacement jump, but also as a function of the gradient of displacement jump.
If yes, can you please point me to the reference?
Dear friends,
I would like to apply angular velocity on a gear in ANSYS. Do you have any idea? Is there any firend having such example? If yes, can you share?
thanks
I am doing my Masters Thesis on Application of Mesh free method on Laser cutting.
I am using Radial point interpolation method for evaluation of the shape functions.I have successfully applied it to the interior nodes and I am using weak form for the nodes on the natural boundaries.
I am facing difficulty in application of numerical integration for the functions in the weak form .I am using circular subdomain and applying Gauss quadrature formula for the numerical integration.
I would be glad if I can get some help in this regard.
Thank you
How do we apply Gauss Quadrature Integration formula to a Circle?
Thank you
