IN MATLAB:

A tensile testing machine such as the one shown in Figure P5.11a and b is used to determine the behavior of materials as they are deformed. In the typical test, a specimen is stretched at a steady rate. The force (load) required to deform the material is measured, as is the resulting deformation. An example set of data measured in one such test is shown in Table P5.11. These Figure P5.11 A tensile testing machine is used to measure stress a strain and to characterize the behavior of materials as they are deformed.
