The Crack Tip Fields of Orthotropic Composite Plate under Bending
-
摘要: 本文对受对称弯曲载荷作用的线弹性正交异性复合材料板的裂纹尖端场进行了有关的力学分析。采用复变函数方法推出了裂纹尖端附近的弯矩、扭矩、应力、应变和位移的计算公式。Abstract: In this paper,mechanics analysis for crack tip fields of linear elastic orthotropic composite plate under symmetric bending load was done.By using a complex variable method,the equations for bending moment,twisting moment,stress,strain and displacement fields near crack tip are derived.
