โœฆ Synopsis


Two integral equation formulations for the determination of the vertical displacement and the bending moment around holes in an elastic plate are presented. Each formulation consists of two equations, the first one an integral equation and an integro-differential equation and the second one two singular integral equations. The equations are solved using B-splines as approximations to the unknowns and the method is applied to the case of one elliptic hole in a twisted plate. ZUSAMMENFASSUNG Zwei verschiedene Integralgleichungssysteme fiir die Bestimmung von die Durchbiegung und die Biegemoment in einer gelochten elastischen Platte werden entwickelt. Die eine Systeme besteht yon einer Integralgleichung und einer Integro-Differentialgleichung und die andere yon zwei singul~iren Integralgleichungen von Cauchy'schen Typus. Bei der Aufl6sung der Systeme werden die unbekannten mit Hilfe "B-splines" ausgedriickt. Beide Systeme werden benutzt in dem Fall von einer elliptischen Loch in einer uendlichen, tordierten Platte.

Nonlinear Volterra integral and integro differential equations with weakly-singular kernel are considered and solved numerically using nonlinear Mathematical programming methods based on minimax approximations. In both cases polynomial and multiquadric approximation are used.
