Tensile and Compressive stress

Stress represents the action of a force or moment on a structural member. If the force pulls the member (tension) it results in tensile stress; if the force pushes the member (compression) it results in compressive stress. Tensile stresses stretch a member and compressive stresses squeeze a member. There is a significant difference between the behavior of a structural member in tension and compression. Depending on how slender the structural member is, it may buckle or crush under compression stresses. However, buckling does not occur when a structural member is subjected to tensile stresses. Tensile stress results in the elongation of the member.

Bending Stresses

Bending is due to the internal moment. Since a moment can be resolved into a couple, the internal moment can be considered as a compression force (C) and a tensile force (T). The compression force results in compressive stresses and tensile force in tensile stresses. Therefore, bending stress is a combination of compressive and tensile stresses due to internal moments. Since the stress across a beam section varies from compression to tension, there is a location at which stress is equal to zero. This is called the “neutral axis”. For a homogeneous beam, the neutral axis passes through its centroid.
