NONLINEAR DYNAMIC RESPONSES OF VISCOELASTICLAMINATED PLATES WITHDAMAGE

The Ladeveze’s damage model of the uni-ply for laminated plates is developed , and it is used to damageanalysis of the generally laminated plates including shear viscoelasticity. On the basis of the Von Karman theory , the non-linear equations of viscoelastic laminated composite plates with damage are derived , and by using the finite differencemethod and iteration method , these equations are solved. Numerical results show that the dynamic responses of the structure will change remarkably when considering the damage and damage evolution.
