It is common practice to obtain stress intensity factors in elastic materials by using Williams series expansions truncated at the r^(-1/2)-stress term. I ask myself, what if both evaluations of experimental and numerical data is improved by including lower order (stronger singularities) terms? The standard truncation is done in a readworthy paper
PhD position for developing an efficient computational platform for additive manufacturing by multi-scale approach and model reduction technique under the framework of finite element and level-set formulation. The additive manufacturing process that will be considered is the SLM process (Selective Laser Melting) for metals.
Dear Mechanician,
we are searching for excellent PhD candidates for the next 3-yrs PhD programme in Systems Science (Track Computer Science and Systems Engineering, research unit MUSAM on Multi-scale Analysis of Materials) of the IMT School for Advanced Studies Lucca (Lucca, Tuscany, Italy) to work on an interdisciplinary research topic across computational mechanics, materials science, optimization, and high-performance computing.

When you push up your sleeves, wrinkles form, which eventually evolve into ridges (pictured). As familiar as you may be with this phenomenon, have you ever thought about its underlying mechanism? It involves the complex nonlinear mechanical behaviour of large deformations and surface instabilities, which in turn give rise to a sophisticated morphological evolution. And now, Yifan Yang and co-workers have revealed a hitherto unknown post-buckling behaviour that involves multiple bifurcation transitions (Phys. Rev.
