ELASTIC BUCKLING OF SIMPLY SUPPORTED RECTANGULAR PLATES UNDER BENDING,SHEAR AND BEARING STRESSES
-
摘要: 采用有限单元法，对处于局部承压与剪切联合作用、局部承压与弯曲联合作用、剪切与弯曲联合作用下的四边简支矩形板进行分析。通过对各自应力作用下屈曲波形的形状进行分析，解释相关曲线的形状。最后对局部承压、弯曲与剪切联合作用下板件的弹性屈曲进行切片分析，提出相关关系公式。Abstract: The buckling of simply supported rectangular plates under bending, shear and local bearing stresses was analysed using ANSYS.The interaction equations between any two kinds of stresses were first studied and approximate formulas were proposed.The shapes of the interactive curves were explained using the buckling wave similarities.Finaly, the interactive surfaces of the three stresses were studied and correlative formula was also suggested.
