Stress Analysis Of Plates On 2 Parameter Elastic
Foundation Using A Non-singular Fundamental
Solution

Abstract
The author and his co-workers have introduced boundary element derivations for
thick Reissner plates on two parameter elastic foundation. The fundamental
solution of this type of problems is usually expressed in terms of modified Bessel
functions K^(z) and K,(z), with z being a real or complex variable, and the kernel
functions containing log z, 1/z, and l/z* singularities. This paper introduces a
modification to the fundamental solution, which leads to the elimination of most
singular terms, and the resulting boundary integral equations can be analysed with
source points on the actual boundary. The fundamental solution is consistent for
characteristic equation roots with real or complex values. Several case studies with
different geometrical shapes, and different boundary and loading conditions, have
been anal
