On the Calculation of Plates by Boundary elements Method

摘要

The accuracy of the plate flexure solution by boundary elements method has been considered, using the approach based on analytical integration of Green functions for the boundary elements. The problem dependence on the boundary elements number for equare plates and various boundary conditions has been studied. Such methods have been compared with the traditional approach, based on numerical integration of Green's functions. In particular it has been established that the utilization of analytical dependences for the coefficients of boundary element method system 2.5-5 times reduced the volume of calculation.
