Inverse mass matrix via the method of localized lagrange multipliers
(National Technical University of Athens, 2017-06)
An efficient method for generating the mass matrix inverse is presented, which can be tailored to improve the accuracy of target frequency ranges and/or wave contents. The present method bypasses the use of biorthogonal ...

Partitioned formulation of contact-impact problems with stabilized contact constraints and reciprocal mass matrices
(John Wiley & Sons, 2021-09)
This work presents an efficient and accuracy-improved time explicit solution methodology for the simulation of contact-impact problems with finite elements. The proposed solution process combines four different existent ...

Large-Step Explicit Time Integration via Mass Matrix Tailoring
(John Wiley & Sons, 2020-04)
A method for tailoring mass matrices that allows large time-step explicit transient analysis is presented. It is shown that the accuracy of the present tailored mass matrix preserves the low-frequency contents while ...
