Finite element mass matrix lumping by numerical integration with no convergence rate loss
Isaac Fried,David S. Malkus +1 more
TL;DR: Using numerical integration in the formation of the finite element mass matrix and placing the movable nodes at integration points causes it to become lumped or diagonal (block diagonal) with the optimal rate of energy convergence retained.
Journal ArticleDOI
A finite element displacement model valid for any value of the compressibility
TL;DR: In this paper, the displacement formulation of the minimum potential energy can be used with the finite element method to approximate both compressible and incompressible equilibria of linearly elastic, isotropic solids.
