Abstract

 
A semi-analytical procedure by means of the nodal line finite difference method. Early developed by the Author, is presented for bending analysis of rectangular platen with nbrupi change in thickness in one direction. To overcome the difficulty ariaed from the discountinulty at the line of abrupt change in thickness. A uniform of the difference equation has been developed and incorporuted in the technique presented. Numerical results obtained by the application of the proposed method are compared with those available from author analytical solution. The compared demonstrates a close agreement, which unthcatea the applicability and versatility of the proposed method as a new technique for solving a clarn of plate bending problems.
