Abstract: Inertia plays a crucial role in the quaternionbased rigid body dynamics, the associated mass matrix, however, presents singularity in the traditional representation. Recent researches demonstrated that the singularity can ...

Abstract: A precise integration algorithm has recently been proposed by Zhong (1994) for dynamic stiffness matrix computations, but he did not give a corresponding eigenvalue count method. The Wittrick-Williams ...

Abstract: The wave propagation constants of periodic structures are computed using the exact dynamic stiffness matrix of a typical substructure. The approach used is to show that wave propagation and the ...
