What is meant by mechanical properties?
Definition. Mechanical properties are physical properties that a material exhibits upon the application of forces. Examples of mechanical properties are the modulus of elasticity, tensile strength, elongation, hardness and fatigue limit.
What is mechanical properties with explain?
The mechanical properties of a material are defined as those properties that influence the material’s reaction to applied loads. Mechanical properties are used to determine how a material would behave in a given application, and are helpful during the material selection and coating specification process.
