newmark
时间积分算法在有限元动力学中的应用，可以计算结构的瞬态响应(This class implements a Newmark beta-gamma predictor-corrector time inte-
gration scheme, with accelerations as primary unknowns.
.A Newmark scheme assigns to the dofs the following 5 unknowns :
- the displacement d and its predictor D
- the velocity v and its predictor V
- the acceletion a .
Their expressions are calculated by the dofs in class Dof.)
