Weight functions are practical tools in linear elastic systems where several discrete or continuously distributed sources cause something, deformation, stress, or related stuff. In linear fracture mechanics, as also in the object of this blog, weight functions are used to calculate stress intensity factors. If the load is divided into discrete or continuous separate or overlapping parts which each gives a known contribution to the stress intensity factor, i.e. has a known weight, calculation for new loads may be reduced to simple algebra instead of extensive numerical calculations.

Multiscale and Multiphysics Mechanics of Materials Research Lab (M4RL) has one Ph.D. position (Graduate Research Assistantship) available in the field of advanced multifunctional durable concrete and cementitious materials. The research work will have both computational and experimental components. Individuals interested in multifunctional concretes, Phase Change Materials (PCMs), multiscale/multiphysics material modeling, experimental mechanics and machine learning are encouraged to apply.

Prof. Wei Cai at the Mechanical Engineering Department of Stanford University is seeking a postdoctoral researcher to lead a project on the modeling of dislocations dynamics in the presence of hydrogen.  The major task of this project is to enable/perform Dislocation Dynamics simulations with hydrogen effects using the ParaDiS program. Molecular dynamics simulations may be required to provide physical input to the Dislocation Dynamics model.  The postdoctoral researcher is also expected to collaborate with external experimentalists working on this project.

A postdoc position is available in the National University of Singapore, on the development of a multi-physics degradation model for building facade materials. Description and application details are provided below.

Viscoelastic materials are receiving increasing attention in soft robots and pressure sensitive adhesives design, but also in passive damping techniques in automotive and aerospace industry. Here, by using the correspondence principle originally developed by Lee and Radok and further extended by Ting and Greenwood, we transform the elastic solutions of Persson for contact of nominally flat but randomly rough surfaces to viscoelastic indentation. As an example, the cases of step loading and of the response to a single cycle of harmonic loading are studied.
