摘要
本文采用一种边界积分方程法,计算了共线周期反平面裂纹的动应力强度因子。对于入射平面SH弹性谐波,分析了波的频率、入射方向以及相邻裂纹间距离对动应力强度因子的影响。
In this paper, a boundary integral equation method is applied to compute the dynamic stress intensity factors of collinear periodic antiplane cracks. For incident plane, time-harmonic and elastic SH waves, the effect of the frequency, the direction of the wave incidence and the distance between neighboring cracks on the dynamic stress intensity factors is analyzed.
