Lecture 1. We explore the basic stress strain curve, using hooks law and stopping at the elastic limit. We introduce the Young’s modulus (modulus of elasticity) and Poisson’s ratio. 

Lecture 2. We move past the elastic limit and in to plastic deformation. We define ductility, resilience and toughness. 

Lecture 3. The concepts of real stress and real strain are developed and the Rockwell hardness test is explained.
