ASYMPTOTIC MODELLING OF TIME-DEPENDENT SIGNORINI PROBLEM WITHOUT FRICTION OF LINEAR THIN PLATE

In a recent paper, Chacha and Bensayah [2], after the one of Paumier[7], have studied the asymptotic modelling of Coulomb frictional Signorinistatic problem of linear plate and nonlinear von Karman plate. Their mainresult is that the leading term of the asymptotic expansion is solution of a twodimensionalSignorini problem but without friction. In this paper, we extendthis study for dynamical frictionless problem.
