Fractal Interfaces In Masonry Structures. Methods Of Calculation

Abstract

Masonry structures involving interfaces with fractal geometry are analysed here as a sequence of classical interface subproblems. These classical sub- problems result from the consideration of the fractal interface as the unique "fixed point" of a given Iterative Function System (I.F.S.). On the inter- face nonmonotone contact and friction conditions are assumed to hold. The methods developed consist an extension of the classical FEM to the case of fractal interfaces. The case of nonconvex energy problems is investigated, and some results from static analysis of masonry walls with prescribed frac- tal cracks are included in order to illustrate the theory. 2 Introdu
