Web19 Jun 2014 · A secondary stress is a normal or a shear stress developed by the constraint of adjacent parts or by self-constraint of a structure. The basic characteristic of a secondary stress is that it is self-limiting. Peak stress is the highest stress in the region under consideration, and the stress typically decays rapidly away from that location.
