摘　　要：利用弹性力学的单位集中不连续位移基本解，给出粘弹性平面问题的不连续位移边界积分方程一边界元方法。数值算例表明，该方法解决粘弹性断裂力学问题是很有效的。The displacement discontinuity boundary integral equation-boundary element method is given basedon the unit concentrated displacement discontinuity fundamental solutions of elasticity. The numerical examplesshow that the method is very effective in solving crack problems in viscoelasticity.
