Abstract:	本文係探討夾固式均向疊層圓型板件在預拉伸及均勻面壓下之非線性大撓曲問題，其掌控方程延自馮卡門大撓曲(von - Karman Large Deflection)理論並納入疊層之考量，其無因次之斜率與面內應力合非線性聯立方程則運用差分法並配合一修正之迭代技巧來求解。針對接近同模數之兩層疊層板件中所得結果發現與文獻之單層均向板件問題相脗合。對於模數有明顯差異之雙層式板件，結果顯示，在較低預拉伸力之條件下，改變疊層之模數比例將對於位移及曲率之徑向變化、以及呈現線性行為之最大面壓產生明顯影響。 Problem of nonlinear large-deflection of a clamped and layered isotropic circular problem under initial tension is studied. The governing equations follow von-Karman large deflection theory accounting for a layered configuration. The simultaneous equation
