【摘要】 本文应用非局部场理论分析了Ⅲ型裂纹受实加荷载作用时裂尖应力场的问题，利用Ｅｒｉｎｇｅｎ提出的简化场方程导出了该问题的对偶积分方程，并通过数值计算方法得到该问题的数值解，结果表明在裂纹尖端应力场是非奇异的。更多还原

【Abstract】 According to the theory of nonlocal eleasticity, the transient problem ofcrack type III on which surfaces suddenlly appeares equal and opposite anti - plane stresses isstudied in this paper. The dual - integral equations for this problem is derived from Eringern s simple field equations and the mathematical solutions of stress field at the crack tip are obtained. Conclution shows these solutions give no stress singularity at the crack tip.更多还原
