The theoretical strength can also be approximated using the fracture work per unit area, which result in slightly different numbers. However, the above derivation and final approximation is a commonly used metric for evaluating the advantages of a material's mechanical properties. Visa mer The theoretical strength of a solid is the maximum possible stress a perfect solid can withstand. It is often much higher than what current real materials can achieve. The lowered fracture stress is due to defects, such as … Visa mer The stress-displacement, or $${\displaystyle \sigma }$$ vs x, relationship during fracture can be approximated by a sine curve, $${\displaystyle \sigma =\sigma _{th}sin(2\pi x/\lambda )}$$, up to Visa mer When a solid is in tension, its atomic bonds stretch, elastically. Once a critical strain is reached, all the atomic bonds on the fracture plane rupture and the material fails mechanically. The stress at which the solid fractures is the theoretical strength, often denoted as Visa mer • Strength of materials • Fracture mechanics • Solid mechanics • Stress (mechanics) Visa mer
