Compressive stress - Compressive stress

...Surface stress is sometimes called surface force or resultant stress, and the component of surface force perpendicular to the surface is called normal stress and is usually represented by σ, while the component parallel to the surface is called shear stress and is represented by τ (Figure 2). When normal stress acts to pull on each other across the surface, it is called tensile stress, and when it pushes against each other, it is called compressive stress. Shear stress acts to displace objects on both sides of the surface. ...

*Some of the terminology explanations that mention "compressive stress" are listed below.

…面の応力を表面力あるいは合応力と呼ぶことがあり，表面力のうち面に垂直な成分を垂直応力といい，ふつうσで表し，一方，面に平行な成分はせん断応力といいτで表す(図2)。垂直応力が面を境として互いに引っ張り合う作用をしているときこれを引張応力，押し合うとき圧縮応力と呼ぶ。せん断応力は面を境としてその両側の物体をずらせる作用をする。…
