摘要: The aim of this study is to investigate failure strength and mode mechanically fastened carbon-epoxycomposite plate which shape trapezium. load are analyzed numerically. numericalmethod includes two steps. First, the stress distribution in calculated by use a finite elementmethod. Second, predicted means Tsai-Hill Tensilecompressivefailure criterion. A computer code was developed can be used calculate maximumfailure load, propagation failure. edge, E/D, side, W/D, distances plateare changed from 1 4 2 respectively, while orientation angle equal 0°. It found thatfull bearing when edge distance ratio 3 side 4.
