Helle Hein


Free vibrations of delaminated beams resting on Pasternak soil are analysed. Differential stretching and bending–extension coupling are considered in the formulation. The influence of soil parameters, size and location of the delamination on the frequencies and mode shapes is investigated. Some numerical examples and comparisons are presented.
