This paper try to mix the finite strip method and hybrid stress element, and deduce a numerical and computer method which combines the advantages of the two methods - mixed hybrid finite strip method ; analyze the intensity and stability of the orthotropic plate by this method ; deduce the formula of the orthotropic plate ' s analysis and calculation under this method ; compile the program of orthotropic plate ' s mixed hybrid finite strip method ( hfsop. for ) with fortran - 77 language, and perform them under fortran90 environment of pc computer ; comparing with traditional methods by example of computing, prove that the mixed hybrid finite strip method have better degree of accuracy, moderating the stiffness of plate, coming more close to actual conditions, avoiding over - hard or over - soft ; finally, this paper analyze the stability of a orthotropic plate by this method, and deduce the - value of critical stress
論文將有限條法和應力雜交元法兩者結合起來，導出一種兼有兩者優點的數值計算方法? ?混合雜交有限條法。運用這種方法對正交異性板的強度和穩定進行了分析，推導出正交異性板在這種方法下的分析計算公式，用fortran - 77語言編寫正交異性板混合雜交有限條法程序（ hfsop . for ）在微機fortran90環境下運行。通過算例與傳統的方法比較，驗證混合雜交有限條法有更好的精度，使板的剛度適中，更接近實際情況，避免「過硬」或「過軟」 ；最後，論文還用此方法對一正交異性板進行了穩定分析，得出臨界應力值。 -
