EOSC 352 · Geophysical Continuum Dynamics

Introduction to tensor calculus and continuum mechanics. Stress, strain and strain-rate tensors. Mass, momentum and energy balance. Applications to problems of geophysical heat transport, elasticity and fluid dynamics illustrated using MATLAB. [3-0] Prerequisite: One of EOSC 250, MATH 317.

Instructors

Instructor: Christian Schoof

TA: Gabriela Racz

Textbook

Required: course lecture notes (see below)

Recommended:

  • Continuum mechanics by G. E. Mase in the McGraw Hill Schaum Outline Series.
  • Geodynamics by D. Turcotte and G. Schubert

I highly recommend the text by Mase as it gives a very succinct description of the basic concepts and the mathematics involved. The text by Turcotte and Schubert also gives an abbreviated introduction, and applies continuum mechanics to real Earth Sciences problems. Some of the matieral in Turcotte and Schubert goes beyond the present course.

Assignments:

I expect to set about 6-7 assignments in this course. They will be due at the end of class on the date indicated below (which I will generally try to make a Friday). No marks for late assignments without a good reason.
