Tensorial damage analysis of viscoelastic plates

The failure process of a middle-thick plate in linear-viscoelastic constitutive description with the application of tensorial continuum damage mechanics is analysed. The damage evolution is considered on the base of Litewka one parameter model [14]. In the numerical solution of creep of the plate FEM has been used. Tne numerical investigations are focused on searching the corelation between the incubation time and the damage tensor eigenvalues.
