Some Recent Advances in Numerical Methods in Structural Dynamics

摘要: The purpose of this paper is to present some recent developments in the area numerical dynamic analysis large structural systems. first part devoted finite element method, a new concept discretization continuum, adoption which effects considerable reduction number degrees freedom for required solution accuracy, when compared with usual method. This followed by brief description eigenproblem techniques, free vibration both rotating and nonrotating structures, that fully exploit associated matrix sparsity. Together, these techniques constitute powerful tool subsequent response complex practical structures.
