Stress strain curve is the plot of stress and strain of a material or metal on the graph In this, the stress is plotted on the yaxis and its corresponding strain on the xaxis After plotting the stress and its corresponding strain on the graph, we get a curve, and this curve is called stress strain curve or stress strain diagram. Tensile modulus or Young's Modulus is the ratio of stress to strain within the elastic region of the stressstrain curve before the yield point Thermoplastic Characteristics ABS Acrylonitrile Butadiene Styrene strong and rigid;. In engineering and materials science, a stress–strain curve for a material gives the relationship between stress and strainIt 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.
