Stress and Strain Issues in Structural Geology
Prof. Soumyajit Mukherjee · IIT Bombay
About
Stress and strain concepts will be explained in structural geological contexts. Several interesting and easy to follow applications will be presented that are otherwise not possible to cover during tight schedule of semesters.
Intended audience: B.Sc. and M.Sc. students in Geology and Geophysics
Prerequisites: Basic geologic knowledge needed, so ideally the first semester of B.Sc. 1st Yr
