【摘要】 文中使用"契合"、复变函数法和移动坐标的方法,给出了SH波入射条件下多个含孔半圆形凸起地形附近多个浅埋圆形孔洞动力分析问题的解答。将模型分成两个区域,在区域Ⅰ和区域Ⅱ中分别构造波函数,最后在两个区域的公共边界上实施"契合",即满足两个区域的公共边界上位移、应力的连续条件。通过算例给出了浅埋圆孔动应力与入射波数、入射波角度的变化规律。更多还原

【Abstract】 Dynamic response of homocentric cavities under a range of semi-cylindrical homocentric hills impacted by SH-wave is studied by using a "conjunction",complex functions,and the multi-polar-coordinate method.The model is divided into two parts,and the scattering wave functions are constructed separately in each one.Then a conjunction is made at common boundaries of the two parts to find the solution of the problem,the displacement and stress continuity conditions on the interfaces are holded.Computational examples are presented,and the influence of wave number and wave incidence angle on dynamic stress concentration factor(DSCF) is discussed.更多还原
