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 … WebClearly, stress and strain are related. Stress and strain are related by a constitutive law, and we can determine their relationship experimentally by measuring how much stress is …

WebFor a small stress, the relation between stress and strain is linear. The elastic modulus is the proportionality constant in this linear relation. Tensile (or compressive) strain is the response of an object or medium to tensile (or compressive) stress. Here, the elastic modulus is called Young’s modulus. mysore history pdfWebStrain is a measure of the amount of stretch or compression along a material (Normal strains), or the amount of distortion associated with the sliding of layers within a material (Shear strains).
