| 摘 要： | 假设材料的剪切模量按双曲函数变化,采用积分变换—对偶积分方程方法,求得裂纹尖端应力场和应力强度因子.研究表明,应力强度因子随裂纹位置的变化而变化,而且裂纹越靠近板边,应力强度因子随裂纹位置的变化越显著.

| Abstract: | The shear modulus was assumed to vary in terms with hyperbolic function.By using integral transformation and dual integral equations,the stress field and stress intensity factor were obtained.It was indicated that the stress intensity factor varys with the variety of the crack location.If the crack is located on the verge of the strip,the stress intensity factor is very sensitive to the variety of the crack location. |

| Keywords: | functionally gradient material antiplane fracture stress intensity factor dual integral equation |
