solid mechanics

In the following video, I have tried to explain the concept of principal stress in a more physical way and without involving any mathematical equations, hope you can easily imbibe the concept.

Aalto University (Finland), Department of Mechanical Engineering, is looking for a doctoral student for a study on the breakage and fragmentation of ice blocks under compressive loads. The fragmentation process is complicated and requires the use of novel modelling methods that can be used reliably on different scales. In addition to the computational work, we will perform experiments on this topic. We start the work using our inhouse FEM-DEM code (other approaches can be also used), while the experiments will be performed in the cold room of our department.

We in Aalto Univeristy (Finland), Department of Mechanical Engineering, look for a post doc to join our group for a study on the breakage and fragmentation of ice blocks under compressive loads. The fragmentation process is complicated and requires the use of novel experiments and numerical models, and in this research, you will be working on both. The unique experiments on this topic will be performed in the cold room of the department.  Numerical modelling will be done on a variety of scales.
