Patterns are used in many fields such as design, linguistics and meteorology, but patterns in the relationship between stress and time are not observed in the field of solid mechanics. By using patterns, it is easy to discover the arrangements of repeated patterns and their distributive biases and differences. Usually, a tensile test was not performed to assess time patterns. This is because it adds uniform tensile force to a material with constant tensile speed. A tensile test using an intelligent universal test machine was performed to assess the relationships of arrival time to set load and strain stability time to control in two types of tensile speed. In this report, we compared the arrival time to set load for a fatigued material and a non-fatigued material. A change in arrival time to set load was seen in the fatigued material. It appeared to have a markedly low level of stress. The test specimen was SCM435H. By using patterns, we identified in a fatigued material a relationship between stress and arrival time to set load.
