摘要
借助于新的应变能函数和变形模式，推出了缺口顶端场各区的渐近方程，得到了顶端的完整描述本文结果表明，在靠近缺口顶端处，应力具有Ｒ－λ［－λ＝２δ（１１＋ｎ－ｎ）］的奇异性，应变具有Ｒ－２δ的奇异性对于不同的材料常数和不同的缺口角度，给出了不可压缩橡胶类材料缺口顶端应力及应变分布曲线。
By the new strain energy function and deformation pattern,the asymptotic equations for each sector of the notch-corner field are derived and solved. The results show that when the notch-corner is approached,the stress and strain possess the singularity R -λ [-λ=2δ(11+n-n)] ,and R -2δ ,respectively.For different material constants and different notch angles,the stress-strain curves of imcompressible rubber-like material are given and the dominant behavior of stress and straim near the notch-corner are revealed.
