PROBLEM TO BE SOLVED: To surely shorten calculation time when simulating behavior of members. SOLUTION: When calculation time is in a range of a time domain TJ, time in which difference between roller velocity V<SB>R</SB>and velocity V<SB>p</SB>at all material points of the members continue keeping a state where the difference is smaller thanε<SB>v</SB>is timed by updating stability determination counter every very small time period, and when the stability determination counter is the stability determination time (CT) or more, the calculation time is set to the end time of the extracted time domain without calculating physical quantity of the members.
