Theoretical strength of materials

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 interior or surface cracks. One of the goals for the study of mechanical properties of materials is 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 … Visa mer • Strength of materials • Fracture mechanics • Solid mechanics 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 Webb1 sep. 2006 · In Table 1 we list the predicted theoretical strengths for several materials for which the fractal dimension values have been published. In most cases, the theoretical strength values in Table 1 are between the estimates that are available in the literature of E / 8 and E . / π.. However, the assumptions in the present approach are quite different …
