Abstract

This paper deals with vibration and buckling analyses of rectangular plates with nonuniform elastic constraints against rotation using the spline strip method. The effect of nonuniformity of elastic constraints and aspect ratios on these problems is analyzed, and the results are also compared with those based on uniform elastic constraints. It is found from the numerical examples that the influence of the nonuniformity of elastic constraints on the natural frequencies and buckling loads become evident.

    To maintain the desired accuracy for the biharmonic equation with mixed boundary conditions, global methods usually require extremely high order approximations around the singularities; see for example the series-based method introduced in [17] to solve the biharmonic problem with mixed boundary conditions. Meanwhile, local methods need to be implemented with adaptive mesh refinement around the singularities or combined with singular function approximations, such as the numerical methods developed in [18–20] to study the vibration and buckling of plates. Even though standard local methods combined with local mesh refinement can be applied to a large variety of singular problems with fewer requirements, singular function methods are preferred since it is generally more efficient provided appropriate functions are chosen to fit the singularities.
