| In this work, the geometrically nonlinear vibrations of composite beams subjected to harmonic loading and thermal changes are used to study the sensitivity of selected vibration response parameters to the presence of damage (delamination). The damage detection criterion formulated earlier for non-heated plates, based on analysing the points in the Poincare sections of the damaged and healthy plate, is modified and tested for the case of beams additionally subjected to elevated temperatures. The importance of the actual temperature in the process of damage detection is shown. |
