1 Lahore University of Management Sciences B.Sc. (Honours) Programme MS Programme Course Outline Course: Continuum Mechanics (Math 364) Pre-requisite: Linear Algebra (Math221), Multivariate Calculus (Math 103) Quarter: Summer Instructor: Dr. Wasiq Hussain E-mail: [email protected] Text: Nonlinear Solid Mechanics, A Continuum Approach for Engineering, by Gerhard A. Holzapfel (2000). (John Wiley & Sons) Reference book: Non-Linear Elastic Deformations by R.W. Ogden, 1997, Dover Publications (New York). Units: 4 Sessions: 5 lectures of 80 minutes per week 2 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.
