With the sample geometry a stress strain curve can then be generated from the recorded load and displacement.
In crs tests and cgts the average strain e ah h or the void ratio e can be related to an average effective stress calculated with the fol lowing equation u a uuo a u u 6 where u is the total vertical applied stress u.
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.
