구조동역학 문제에서 전단계 오차추정치를 이용한 자동시간간격 조정 알고리듬

Abstract

A prior error estimator which is solving structural dynamic problems and which is based on the generalized- method, is developed. Since the proposed error estimator is computed with only previous information, the time step size can be adaptively selected without the feedback mechanism. This paper shows that the automatic time stepping algorithm using the error estimator performs an efficient time integration. To verify its efficiency, several examples are numerically investigated.
