WebbThe following are basic definitions and equations used to calculate the strength of materials. Stress (normal) Stress is the ratio of applied load to the cross-sectional area … WebbTheoretical Strength of Crystal: Materials, when exposed to external forces, will deform or fail. This may occur by :-It is possible to estimate the theoreticalstrength of a “perfect” material (i.e., a material that contains no defects).Theoretical strengths are related to interatomic forces , temperature , state of stress .
