WebStress is a difficult quantity to measure. Some sensors directly measure stress (concrete stress sensors, soil stress sensors), but typically stress is measured indirectly by measuring the strain on an object, and then converting it to stress using Hooke’s law ( Equation 3 ). 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 …
