At the microscopic level matter is discontinuous. It is composed of molecules and
atoms. However, in real life we are concerned with volumes of matter with
dimensions large compared with these particles. CONTINUUM MECHANICS
deals with the behaviour of bodies of solids and fluid matter on a macroscopic
scale. It disregards the microscopic structure and treats matter as being smoothly
distributed throughout the body under consideration.
GOALS:
1. To provide an introduction to the basic theoretical ideas in continuum mechanics
using the theory of CARTESIAN TENSORS.
2. Apply the theory in the solution of different types of problems in nonlinear
elasticity.
