Análise dinâmica elasto-plástica de transiente de curta duração incluindo os efeitos da interação solo-fluido-estrutura
… the dynamic equilibrium equation and a diagonal lumped mass matrix is employed with a special procedure applicable to variable nodal points quadrilateral isoparametric elements. The effects of soil-structure interaction are considered and a special fluid element is appreciated. Several problems …

Finite Element Analysis of Thermoviscoplastic Deformations of an Impact-Loaded Prenotched Plate
… elements, one point integration rule, and a lumped mass matrix. The Lagrangian description of motion is used to describe deformations of the plate. The coupled nonlinear partial differential equations are first reduced to coupled nonlinear ordinary differential equations (ODEs) by using the …

A unified approach to the formulation of non-consistent rod and beam mass matrices for improved finite element modal analysis
… rigid-body modes to verify the conservation of mass inertias is presented. Conservation of rod element mass guarantees convergence to the exact eigensolutions of a rod. Conservation of beam element mass guarantees convergence to the exact eigensolutions of a Bernoulli-Euler beam without rotatory …

Development and Applications of a Flat Triangular Element for Thin Laminated Shells
… of the element. Hence obtaining the consistent mass matrix or the derivatives of the transverse displacement that are required for forming the geometric stiffness matrix is not straight forward. This problem is alleviated by borrowing shape functions from other similar elements or using simple …

Nonlinear finite element analysis of reinforced concrete structures subjected to blast loading
… lumping scheme has been employed to generate the lumped mass matrix from the consistent mass matrix for both concrete and steel. The compressive behaviour of concrete is modelled as a strain rate sensitive elasto-viscoplastic material. The onset of viscoplastic behaviour and the softening regime …
