Volume modulus of elasticity distribution of forces and yield strength affect the impact strength of a material. In order for a material or object to have a high impact strength the stresses must be distributed evenly throughout the object. It also must have a large volume with a low modulus of elasticity and a high material yield strength. Ultimate tensile strength (UTS) often shortened to tensile strength (TS) ultimate strength or within equations is the maximum stress that a material can withstand while being stretched or pulled before breaking. In brittle materials the ultimate tensile strength is close to the yield point whereas in ductile materials the ultimate tensile strength can be higher.
