DUGDALE MODEL ADAPTED TO THE TRANSVERSE BENDING OF PLATES

The Dugdale mathematical model is developed for the cylindrical bending of thin plates. The results of cylindrical bending tests on polycarbonate are presented where plastic-zone size measurements are compared to the derived theoretical model. Good agreement is found although large deformations were encountered. The reasons for the validity of the theory as well as the good correlation between theory and experiment are discussed. Finally, compression plastic zones are presented and their relation to crack closure discussed.
