stress crack

[′stres ‚krak]
(mechanics)
An external or internal crack in a solid body (metal or plastic) caused by tensile, compressive, or shear forces.

stress crack

An external or internal crack in a plastic caused by internal or external tensile stresses; environmental conditions frequently accelerate the development of such cracks. Also see crazing.
