Objectives
The objective of the course is to equip students with the capability of solving boundary value problems in small deformation linear elasticity and thermoelasticity using various mathematical methods involving direct solution and energy minimization techniques. This course has ESO202 (Mechanics of Solids) as a prerequisite.
