一、前言 鉴于复合材料层板的结构特点和独特的破坏机理,作者曾经讨论过最近发展起来的固体力学新分支——连续介质损伤力学在复合材料层板中的应用,并指出了损伤力学可能是研究含缺陷复合材料强度的更有效的工具。 从70年代到现在,各向同性损伤理论已经得到了仔细的研究,并在大变形塑性损伤,蠕变损伤和疲劳损伤等方面的应用中取得了初步成功。然而实际上损伤往往表现有各向 I. INTRODUCTION In view of the structural characteristics and unique failure mechanism of composite laminates, the author has discussed the recently developed new branch of solid mechanics, the application of continuum damage mechanics in composite laminates, and pointed out that the damage mechanics may It is a more effective tool to study the strength of composites with defects. From the 1970s to the present, the isotropic damage theory has been carefully studied and has achieved initial success in the applications of large deformation plastic damage, creep damage and fatigue damage. However, in fact, damage often shows different directions
