Optimal constrained layer damping with partial coverage
JL Marcelin, P Trompette, A Smati - Finite elements in Analysis and Design, 1992 - Elsevier
This paper deals with the optimal damping of beams constrained by viscoelastic layers
when only one or several portions of the beam are covered. An efficient finite element model
for dynamic analysis of such beams is used. The design variables are the dimensions and
prescribed locations of the viscoelastic layers and the objective is the maximum viscoelastic
damping factor. The method for non-linear programming in structural optimization is the so-
called method of moving asymptotes.
