In the formula , our experience in structural strength design and the experimental results are considered . and such factors are also considered as differences in materials of the skin and the reinforcer , effects of bending , torsion , stretching and offcenter of the reinforcer . furthermore , through post - buckling stress analysis of the skin , it is shown that even low stress level will result in buckling of the skin , but the skin still has loading capacity 在總結(jié)過去結(jié)構(gòu)強度設(shè)計和試驗分析的基礎(chǔ)上,應(yīng)用扁殼理論,在廣義力與廣義應(yīng)變關(guān)系中考慮了蒙皮與加筋不同材料以及加筋的彎曲、扭轉(zhuǎn)、伸縮和偏心等的影響,推導(dǎo)出適合于工程應(yīng)用的加筋殼結(jié)構(gòu)軸壓屈曲臨界載荷的計算方法;并通過對薄壁結(jié)構(gòu)蒙皮后屈曲應(yīng)力分析,說明蒙皮在很低的應(yīng)力水平時就出現(xiàn)失穩(wěn)現(xiàn)象,但失穩(wěn)后的蒙皮仍具有一定的承載能力。
