THE METHOD OF CENTROID LUMPED MASS IN THE FINITE ELEMENT

  • The lumped mass at the centroid will gives moreaccurate results for dynamic problems, and also make it possibleto optimize the element inertia effect and improve thematching between the element inertia and deformation effects. The detailedanalyses of the frequency-dispersion effect for a one-dimensional problemshows the validity of the method.
