Static and Dynamic analysis of rectangular isotropic plate using multiquadric radial basis function
Journal Title: International Journal of Management, IT and Engineering - Year 2012, Vol 2, Issue 8
Abstract
This paper presents a methodology based on the collocation multiquadric radial basis functions to analyze the static and dynamic behavior of isotropic rectangular plates. The inertia and dissipative terms are evaluated by employing Newmark implicit time marching scheme. The spatial discretization of the differential equations generates greater number of algebraic equations than the unknown coefficients. The multiple linear regression analysis, based on the least square error norm, is employed to obtain the coefficients. Convergence study has been carried out. The clamped and simply supported immovable rectangular plates subjected to uniformly distributed loadings are studied. Results have been compared with the results obtained by other numerical and analytical methods.
