In engineering and materials science, a stress–strain curve for a material gives the relationship between stress and strain. It is obtained by gradually applying load to a test coupon and measuring the deformation, from which the stress and strain can be determined (see tensile testing). These curves reveal many of the properties of a material, such as the Young's modulus, the yield strength and the ultimate … WebbFör 1 dag sedan · Discover how the body works — and what happens when things change — with the latest health news, articles and features from the experts at Live Science
