Detailed Description

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

Bossak integration scheme (for linear and nonlinear dynamic problems) for displacements adjusted for Material Point Method.

This is an implicit scheme based of the Bossak algorithm for displacements suitable for quasi-static and dynamic problems. Furthermore, this scheme has been adjusted for mixed formulation where pressure is also solved as one of the DoFs. The parameter Alpha of Bossak introduces damping, the value of Bossak is from 0 to -0.5 (negative) Implementation according to: "An alpha modification of Newmark's method; W.L. Wood, M. Bossak, O.C. Zienkiewicz; Numerical Methods in Engineering; 1980" MPM implementation according to: "Implicit time integration for the material point method"; J. E. Guilkey, J. A. Weiss The parameter Alpha of Bossak introduces damping, the value of Bossak is from 0 to -0.5 (negative)
