Tensile Strength is the maximum stress that a material can withstand while being stretched or pulled before failing or breaking.
Elastic modulus is a number that measures an object or substance's resistance to being deformed elastically (i.e., non-permanently) when a force is applied to it. A stiffer material will have a higher elastic modulus.
