Bending Stress

Definition - What does Bending Stress mean?

Bending stress is the normal stress that an object encounters when it is subjected to a large load at a particular point that causes the object to bend and become fatigued. Bending stress occurs when operating industrial equipment and in concrete and metallic structures when they are subjected to a tensile load.

Corrosionpedia explains Bending Stress

When a material is attacked by corrosion, the internal grain mesh is weakened and the material tends to loose its strength, hardness and toughness.

A corrosive attack on a metallic structure can cause the creation of small cracks, dents and pitting, which ultimately leads to further corrosion and deeper cracks over time due to tensile stress acting on the edges of the cracks. These scenarios create additional stress on the structure, leading to stress corrosion cracking and bending of the metallic beams and load carriers in the structure. These situations can cause catastrophic failure without significant deformation of the structure.
