摘要
利用推广的Stroh方法,得到含有圆孔无限八次对称二维准晶材料的格林函数。进一步采用半解析半数值的边界元方法,获得在均匀边界加载作用下,有限八次对称二维准晶体内的圆形孔口所引起的应力解答,并分析半径尺寸以及不同加载情况对圆孔边应力的影响。
By using the extended Stroh formulism, the Green’s function of an infinitely octagonal twodimensional quasicrystal with a circular hole is obtained. Furthermore, the semi-analytical and semi-numerical boundary element method is used for obtaining the solution of stress caused by a circular hole in a finite octagonal two-dimensional quasicrystal under uniform loading, and the influence of radius size and different loading conditions on the stress of the edge of hole is analyzed.
