| Abstract: | A new boundary element formulation for Reissner’s plate bending is pressented.This form of BEM has an advantage in that the bending stresses on the bonndary can becalculated directly from the numerical solution, and avoids the use of tangential derivativesof displacement to find plate bending st resses on the boundary,The effectiveness of theapproach is also discussed through some test examples。In the present BEM formulation,the singular orders of the two kernels are same ais that in the standard BEM formul... |
