A Note on the Legendre Series Solution of the Laplace Equation for Cylindrical Problems

The mechanical modelling of cylindrical problems is addressed. A series solution is considered of the Laplace equation, in which the series terms of the stress function Φ are expressions based upon Legendre polynomials and logarithmically singular functions. An explicit form of a polynomial supplementing each logarithmically singular part of the series solution is obtained.The mechanical modelling of cylindrical problems is addressed.
