本文旨在探討含多個圓孔的二維複合材料疊層板,在無窮遠處受一單軸向拉伸負載作用時,以有限元素法,研究在不同的疊層順序與開口間距下,對其應力集中因子的影響,而藉由有限元素套裝軟體『ANSYS』來進行本文的模擬與分析。
本文分析了纖維走向0度與90度之多圓孔單層板以及Cross-ply[0/90]2s和Quasi-isotropic [0/+45/90/-45]s之多圓孔疊層板,數值結果呈現應力分佈會隨著疊序不同而有所變化。當疊層板的多個開口位於X軸時,開口之間每增加1mm的距離,最大應力值上升的數值差距甚微,而多開口數量較少時,其降低的數值較顯著。當疊層板的多個開口位於Y軸時,開口之間每增加1mm的距離,最大應力值減少的數值越來越小,而多開口數量較少時,其增加的數值較顯著。
The 2D stress concentration factors in laminated composite plates with multiple holes and notches under unidirectional tensile stress have been studied using finite element method. The aim of author is analyze the effect of different stacking gradation and distance between the holes upon stress concentration factor. Analysis has been done for symmetric composite laminates, and the finite element formulation is carried out in the analysis section of the『ANSYS』package.
The variations of stress concentration factors in regard to different stacking gradation and distance between the holes are presented in graphical form and discussed. When the holes located on X axis, the stress concentration factor will be reduced; located on Y axis, the stress concentration factor will increase.
