摘要
重点对含I型裂纹正交异性功能梯度材料板的应力场和位移场进行理论分析。首次推出了正交异性功能梯度材料板的裂纹尖端应力场、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理论价值和工程使用价值。
In this paper the fracture analysis on Mode Ⅰ crack in orthotropic functional gradient materials is carefully studied. The stress and strain fields near crack tip have been successfully derived. Gradient stress intensity factor is firstly introduced. The results derived in this paper will be useful in fracture analysis of functional gradient materials.
