概括

金属腐蚀并没有显著影响由不钢或合金制成的微型植入物在人工唾液中的扭曲断裂阻力,即使是用化物. 这两种材料都表现出在扭力下对断裂的抵抗力,不钢变形和合金由于脆性而断裂.

Residual Stresses in Circular Shafts

In materials that exhibit elastic and plastic behavior, known as elastoplastic materials, residual stresses can accumulate when these materials experience plastic deformation. This deformation arises from either high levels of shearing stress or significant strains. Residual stresses are internal stresses that persist within a material after removing the external force causing deformation. This phenomenon is demonstrated when observing the behavior of a shaft under torque; notably, the...
