Definition of compressive stress and strain
WebNormal strain Greek letter ε(epsilon) When bar is elongated, strains are tensile (positive). When bar shortens, strains are compressive (negative). Define normal strain ε as the change in length δdivided by the original length L o (ε = δ/ L o). A o L o P P L+ o δ Example: Prismatic bar has length L o = 2.0 m. A tensile load is WebFeb 16, 2006 · Strain is the response of a material to stress.
