Detailed Description

template<class TSparseSpace, class TDenseSpace>
class Kratos::ResidualBasedBossakDisplacementScheme< TSparseSpace, TDenseSpace >

Bossak integration scheme (for linear and nonlinear dynamic problems) for displacements.

This is a dynamic implicit scheme based on the Bossak algorithm for displacements. The Bossak Alpha parameter ranges from 0 to -0.5, and introduces damping. Implementation according to: "An alpha modification of Newmark's method; W.L. Wood, M. Bossak, O.C. Zienkiewicz; Numerical Methods in Engineering; 1980"
