Numerical Solutions of Singular Integral Equations for Planar Rectangular Interfacial Crack in Three Dimensional Bimaterials

  • 摘要: 基于体积力法,研究了双材料接合半无限体三维矩形界面裂纹的应力强度因子问题.在数值计算中,未知的体积力密度采用基本密度函数和多项式乘积的形式来近似,其中基本密度函数是根据界面裂纹应力的振荡奇异性来选取的.计算结果表明,基于本算法得到的数值结果其收敛精度和计算误差都是令人满意的.算例中,给出了应力强度因子随矩形形状及双材料参数的变化规律.
