应力 Stress (mechanics)(重定向自Normal stress)
![]() ![]() 在连续介质力学里,应力定义为单位面积所承受的作用力。以公式标记为 其中, 假设受力面积与施力方向正交,则称此应力分量为正向应力,如图1所示的 「内应力」指组成单一构造的不同材质之间,因材质差异而导致变形方式的不同,继而产生的各种应力。 采用国际单位制,应力的单位是帕斯卡(Pa),等于1牛顿/平方公尺。应力的单位与压强的单位相同。两种物理量都是单位面积的作用力的度量。通常,在工程学里,使用的单位是megapascals(MPa)或gigapascals(GPa)。采用英制单位,应力的单位是磅力/平方英寸(psi)或千磅力/平方英寸(ksi)。

Stress (mechanics) 应力(重定向自Normal stress)
![]() ![]() ![]() ![]() In continuum mechanics, stress is a physical quantity that expresses the internal forces that neighboring particles of a continuous material exert on each other, while strain is the measure of the deformation of the material. For example, when a solid vertical bar is supporting a weight, each particle in the bar pushes on the particles immediately below it. When a liquid is in a closed container under pressure, each particle gets pushed against by all the surrounding particles. The container walls and the pressure-inducing surface (such as a piston) push against them in (Newtonian) reaction. These macroscopic forces are actually the average of a very large number of intermolecular forces and collisions between the particles in those molecules. |
