Stress σ, strain ε and time t can be measured with the newly developed material test machine, called an intelligent universal test machine. This material test machine can measure the boundary of elasticity and plasticity of a material with an indistinguishable yield point. The relationship between stress and strain from the elastic region to the plastic region was obtained using an intelligence universal test machine with a formula derived employing another system. The results revealed that by using two coefficients and a power function, ε=Sσ^p can be derived. New discoveries of the strength of materials are being researched by making use of the above relational expression. A theory concerning an example that consists of two or more components was elucidated in this study. It was shown that the occurrence of elastic deformation and plastic deformation can be predicted by making use of the intersection method. In addition, the theory was verified.
