Intro to Strain - Lesson 1

Strain is a description of deformation.  Especially, it measures the relative displacement of particles in the body that excludes rigid-body motions. Consider the deformation of the tennis ball the racket net when they are in contact. Total displacement cannot tell the distortion in the material but strain can.

 In this lesson, we will discuss the importance of strain.
