The mechanical properties of a material are generally expressed in terms of the relationship between stress and strain. The mechanical properties of a material can now be correctly determined by the method used to controlling of a testing machine. In this research, a tensile test for stainless steel SUS303 with an indistinguishable yield point was carried out using an intelligent universal test machine. For each relationship between stress and strain, stress and time, and strain and time, the action at every second of the elastic and plastic regions was shown. The elastic region showed the shape of a saw blade, and the plastic region showed the shape of stairs. Moreover, the formula was obtained to be a power function for each relationship. When determining a formula, it is necessary to determine the boundary of elasticity and plasticity. By this measurement method, the boundary of elasticity and plasticity can be shown clearly.
