X. Lin et J. Ballmann, THE EXISTENCE AND UNIQUENESS OF SOLUTIONS BY THE COVERING DOMAIN METHOD IN LINEAR ELASTOSTATICS, Zeitschrift fur angewandte Mathematik und Mechanik, 76(2), 1996, pp. 93-104
The paper deals with problems of linear elastostatics with multiply co
nnected solution domains. Generally, a multiply connected domain can b
e represented in a non-unique way by the intersection set of n > 1 dom
ains, each of which covering completely the original solution domain.
If exact analytical solutions can be found in the covering domains, th
en, making use of the superposition principle, the solution of the ori
ginal problem can be constructed by summation of the n solutions of th
e covering domains. Following this idea, the ''Covering Domain Method'
' is developed, by which the original problem is transformed into a sy
stem of Fredholm integral equations which finally offers the solution
of the problem. In this paper we consider the existence and uniqueness
of the solutions for different choice of covering domains. Two theore
ms are presented, which are useful for the application of the covering
domain method in elasticity.
