Summary
The interaction of a straight crack with a center of dilatation in an infinite elastic plane is investigated. Analytical solutions for the stress intensity factors, the generalized interaction forces and the potential of the system are derived. Furthermore, the contact problem, arising in the case of partial crack clusore, is solved for the limit cases of frictionless and of ideally rough crack faces.
Übersicht
Es wird die Wechselwirkung zwischen einem geradem Riß und einem Dilatationszentrum in einer unendlichen elastischen Ebene untersucht. Für die Spannungsintensitätsfaktoren, die verallgemeinerten Wechselwirkungskräfte und für das Potential des Systems werden Lösungen in analytischer Form hergeleitet. Daneben wird für den Fall des partiellen Rißschließens das Kontaktproblem für die Grenzfälle ideal glatter bzw. ideal rauher Rißflanken gelöst.
