摘要
对含Ⅱ型裂纹正交异性功能梯度材料的应力场和位移场进行理论分析,并首次推导出正交异性功能梯度材料的裂纹尖端应力场、位移场和梯度应力强度因子的理论计算公式.本研究成果对功能梯度材料的断裂分析有重要的工程使用价值和理论价值.
Fracture analysis has been made on mode Ⅱ crack in orthotropic functional gradient materials, and the stress and strain fields near crack tip have been successfully derived. Mode Ⅱ gradient stress intensity factor is firstly introduced. The results derived in this paper will be useful in fracture analysis of functional gradient materials.
