• 中文摘要： 本文主要目的在推導一簡單且有效之分析模式，俾利於含圓孔對稱複材層疊板層問應力之定性分析。首先將依據先前已發展之含圓孔對稱複材層疊板層間應力解析解進而推導沿孔緣層間應力與面內應力關係式；最後，將定義二個可由Lekhnitskii二維非均向彈性力學解與古典層板理論解得之面內應力參數σ(k)、τ(k)來決定含圓孔對稱複材層疊板沿孔緣層間應力比。本文最大優點在於可迅速且準確的決定層疊板內各層間應力相對值；因此，對於工業上常用之複材厚板可快速分析得到其最臨界層間應力交接面。如此一來，將可提供後續細步分析所需注意之臨界層間應力交接面及大量節省整體分析時間，故對於工程上初步及細步分析均有相當之助益。
• 英文摘要： A new method is presented to determine the interlaminar stress ratios around a circular hole insymmeiric laminates under a set of far-field inplane loads. Based on the authors recently developed methodfor calculating the interlaminar stress distributions around a circular hole in symmetric laminates, twoequations relating the interlaminar stresses to inplane stresses are established. In addition, two inplanestress parameters, τ and σ, as calculated by Lekhnitskii's two-dimensional anisotropic solutions in con-junction with classical lamination theory, are introduced to determine the interlaminar stress ratios at theinterfaces of a laminate. Numerical examples are compared with existing solutions to show that the presentmethod would greatly aid designers in considering the delamination effect of notched laminates with relativeease and effectiveness.
