The paper presents results of theoretical investigation on the character of energy dissipation in composite structures subjected to cyclic loading with various shapes of excitation signals. Such loading implies the occurrence of the self-heating effect due to the hysteresis, occurred from viscoelasticity of a polymer. Results of theoretical analysis show the differences between investigated cases, namely sine, square, triangle and sawtooth excitation signals, and their influence on the intensification of structural degradation of polymeric composites. The theoretical results were verified experimentally on the laboratory stand.
