COMMUNICATIONS IN NUMERICAL METHODS IN ENGINEERING Commun. Numer. Meth. Engng (2008) Published online in Wiley InterScience (). DOI: 10.1002/cnm.1110 Nonlinear transient dynamic analysis by explicit ﬁnite element with iterative consistent mass matrix Shen Rong Wu1, ∗, † and Weifeng Qiu2 1Research and Advanced Engineering , Ford Motor Company, 2101 Village Road, MD2115-SRL , Dearborn , MI 48124 , U.S.A. 2 The Institute for Computational Engineering and Science, University of Texas, Austin , TX, U.S.A. SUMMARY Various mass matrices in the explicit ﬁnite element analyses of nonlinear transient dynamic problems are investigated. The matrices are obtained as a linear combination of lumped and consistent mass matrices. An iterative procedure to calculate the inverse of the consistent and the mixed mass matrices in the framework of explicit ﬁnite element method is presented. The convergence of the iterative procedure is proved. The inverse of the consistent and mixed mass matrices is approximated by the iteration and is used to compare the results from the lumped mass matrix. For the impact of a structural component and a vehicle, some difference in the results by using coarse mesh is observed. For the component using ﬁne mesh, no signiﬁcant difference is found.
