Theoretical foundations [Elektronische Daten] [P. Fotiu] Summary: In the first part of this paper an integral representation of the dynamic behaviour of thin plates is developed where two distinct types of internal defects, namely viscoplastic flow and ductile microfracture are considered. Nucleation and propagation of such defects constitute a dissipative process. Thus, the total dynamic response of the structure is composed of the reaction due to external loading and of that due to the development of defects, which are considered as an internal excitation. In plates the unity source of this internal excitation assumes the form of a curvature singularity. The evolution equations for the internal variables describing the dissipative processes are derived from thermodynamic considerations. A numerical treatment of the problem is contained in part two.
