摘要：

A framework is described for modelling an elastic continuum using a grillage of beam-like structural elements derived from discrete element concepts. The beam element properties are derived in detail and implemented in a structural analysis code For validation against classical two-dimensional plane elasticity solutions. The framework offers the possibility of modelling the onset and propagation of fracture in materials that are initially continuous, without the need for specialized elements or remeshing in the context of traditional finite elements.
