    Abstract

    [Truncated] We consider topologically interlocking structures - a new class of blocky structures in which each block is kept in place by its neighbours topologically without any connectors or binder phase. Being constrained from periphery, interlocking structures are capable of keeping their integrity under loading and are tolerant to failure of their elements. The geometrical possibility of such structures opens up new opportunities in building mortarless and demountable structures, flexible foundations and protective layers. The aim of this thesis is to study the mechanical properties of assemblies of interlocked blocks pertinent to civil engineering applications.
    Two classes of blocks are considered; tetrahedral and Osteomorphic blocks. The tetrahedral blocks represent the class of simple convex shapes (i.e. shapes without stress concentrators). For this class, interlocking is achieved by positioning each tetrahedron on its edge (a special template is needed) and stacking them in a layer such that each tetrahedron touches its four neighbours face-to-face. The Osteomorphic block or brick is designed from a parallelepiped after making two opposite faces non-planar. These faces are engineered in such a way that they ensure interlocking when the blocks are assembled in masonry-type structures, both wall-like and corner-like.
