This document outlines various modes of material failure from The Ohio State University researcher Starkey. It describes 14 practical fail modes including elastic deformation, yielding, fatigue, corrosion, wear, impact, fretting, creep, thermal shock, radiation damage, and bending. Each fail mode has multiple inducement agents such as force, time, temperature, and reactivity. Failures can occur in the bulk material or on the surface.
