It has been thought by the finite element community that the consistent mass matrix should not be used as it leads to a higher computational cost and this opinion has been prevalent since 1970. We are of the opinion that in today's age where computers have become so fast we can use the...

The consistent mass matrix of the element is given by (12.26) where A is the uniform cross-sectional area, and l is the length of the element. Thus, the consistent mass matrices, in general, are fully populated. On the other hand, the lumped mass matrix of the element can be obtained...

In this paper, the Hamiltonian system of EM waveguide is introduced and the consistent and lumped mass matrices are constructed after symplectic regularization and semi-analytical discretization.本文在介绍这一体系之后,经半解析横向离散及辛正则化,给出了类凝聚和协调质量阵。 lumped mass更多例句 词组短语 ...
consistent and lumped mass matrices are much smaller than the condition numbers of stiffness matrices, and the condition numbers of stiffness matrices for the Lagrangian elements with equally spaced nodes are far beyond those of the Lobatto elements’ stiffness matrices and grow very quickly as the ...
However, the model proposed in this study comprises primary (fast) and secondary (slow) ozonation stages, which is still consistent with the literature [59]. Fig. 3 shows the profile predicted by the model as a solid line, while the fits of the pseudo-first-order model to Dataset 1 and...

First the consistent mass matrices are derived for the distributed mass systems by considering equivalent density functions for torsion, bending and axial directions. The consistent mass matrices for the lumped systems are obtained from those for the distributed systems by considering the limiting case ...
