**r5.05.02** Algorithms for directly integrating the DYNA_VIBRA/BASE_CALCUL operator =' PHYS '
=============================================================================================

**Summary:**

This document describes time integration schemes that are used to directly solve dynamic problems in **linear transient mechanics**. The diagrams in NEWMARK and WILSON - :math:`\theta` are detailed, as are the "centered differences at a constant step" and "adaptive time step" schemes.
