This paper is the research on the local interactive buckling behavior of cold - formed rectangular tube under uniform compression . the paper includes the following main contents : ( 1 ) an elastic interactive buckling model is presented on the basis of the theory of elastic plates . under the equilibrium condition and deformation compatibility condition , analytical expressions are derived to predict the interactive bucking load pcr 本文主要研究冷弯薄壁矩形钢管均匀受压下板组的相关关系,包括以下主要内容: ( 1 )建立了弹性相关屈曲解析法分析模型,考虑平衡条件及变形协调条件,建立板组的屈曲微分方程,得出了板组相关屈曲的临界荷载p _ ( cr )的计算行列式。
Then i consider a correlative problem : where m , > 0 , s is a bounded domain with smooth boundary in ; v is outward normal vector on ; f ( s ) is continuous function and satisfies some increasing conditions ; u0 ( x ) is a positive function satisfying some compatibility conditions , to obtain the blow - up conditions of the positive solution using the method of subsolution and supersolution , extend the result of song and zheng )上的单位外法向; u _ 0 ( x )是正的函数且满足一定的相容性条件:讨论m 1的情况时,在何种条件下使得问题的正解整体存在或是在有限时刻爆破。主要采用上下解的方法来得到结论。随后考虑相关问题:其中m , 0 ,为r ~ n ( n 1 )中的有界域,具有适当光滑的边界(
