Definition

Reciprocal interactions in which chemical processes (reactions, sorption, phase changes, chemical degradation) alter mechanical properties, stresses or geometry of a material, and mechanical deformation, stress state or fracture alter chemical behaviour, transport rates or reaction pathways; examples include stress‑assisted corrosion, swelling‑induced cracking, hydrogen embrittlement and chemo‑ela
