heal.abstract	A combination of the classical finite-element and the singular-integral-equation method with the help of Schwarz's Alternating Method (S.A.M.) is presented. In this way the flexibility of finite-element method is complemented by the undisputed power of the singular integral equation method in describing singular fields. The result is the creation of a powerful hybrid method convenient for the efficient solution of problems of stress fields containing any type of singularity. The examples considered in the paper indicate the excellent approximation obtained by the method even when using only a few classical elements. © 1982.	en
