碩士 === 國立中興大學 === 應用數學研究所 === 83 === Two models are established to deal with the buckling problem of one-dimensional beam-plates with a number of delaminations. One is the free mode model, and the other one is the constrained mode model. Successive corrections of buckled segments are made on the free mode model by inserting constrained mode model in place of the portion where overlapping of the upper and lower parts in delaminated segments occurs. The approach realistically describe the mode of buckling. The general analysis presented in the thesis is applicable to beam-plates having any end supporting conditions, any number of delaminations at any locations along the beam, and each delamination may occur at any interface. Numerical examples are presented for illustrative purposes.
