抄録

In this study, in order to realize real-time deformation analysis in environment of virtual reality, a new efficient time integration scheme for finite element method is proposed. The proposed method is called 'iterative Newmark' method. In this method, it is not necessary to calculate the inverse of coefficient matrix as in the explicit time integration scheme and has a similar stability criterion to the conventional Newmark method. Several numerical examples validate the efficiency and moderate accuracy of the proposed method.
