✦ Synopsis

Mixed methods solved by an iterative process have been shown to provide an inexpensive procedure for improving the results of standard displacement analysis. This paper shows the possibilities present in their application to dynamic problems, where again accuracy improvement is achieved at small additional expense.

The advantages of the formulation presented are particularly noteworthy in explicit forms where the difficulties of 'hour-glass' modes associated with minimal integration rules ae avoided without cost increase.

## Abstract 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 mix
