Opis stanu zarysowania lepkosprężystej tarczy w ujęciu dystrybucyjnym

The paper contains a mathematical model of viscoelastic plate with cracks loaded in its plane. The crack has been characterized by the discontinuity of the displacement vector. The distributional differential equation of the viscoelastic plate with crack, appropriate boundary conditions, initial conditions and compatibility conditions, have been derived by the variational method of Gurtin in the space of general Functions. An approximate method of solution resulting from the elastic – viscoelastic analogy has been given.
