Stress–strain curve
open-in-new
<p>In <a href="/facts/Engineering/RFVg8H3I">engineering</a> and <a href="/facts/Materials_science/N5HrXRYW">materials science</a>, a stress–strain curve for a material gives the relationship between <a href="/facts/Stress_(mechanics)/ErAXDbbd">stress</a> and <a href="/facts/Strain_(mechanics)/xK7R59oI">strain</a>. It is obtained by gradually applying <a href="/facts/Structural_load/MAxjDyhc">load</a> to a test coupon and measuring the <a href="/facts/Deformation_(engineering)/z1LEmkQX">deformation</a>, from which the stress and strain can be determined (see <a href="/facts/Tensile_testing/f3vF9ped">tensile testing</a>). These curves reveal many of the <a href="/facts/List_of_materials_properties/Cg2LVoQe">properties of a material</a>, such as the <a href="/facts/Young%2527s_modulus/MV5JMCIM">Young's modulus</a>, the <a href="/facts/Yield_strength/mrSg02gW">yield strength</a> and the <a href="/facts/Ultimate_tensile_strength/Cv2jPplR">ultimate tensile strength</a>. </p>
