Fracture analysis for bi-modular materials

Modelling fracture formation in bi-layered materials, with applications to tree bark and drying mud

In this paper we present a model of fracture formation on surfaces of bi-layered materials. The model allows synthesis of realistic patterns occurring in nature as a result of cracking induced by growth or shrinkage of one layer with respect to another. Two different discretizations of the problem are discussed. First we revisit an existing mass-spring approach, then we introduce an approach ba...

Fracture of Dental Materials

Advances in fracture and numerical analysis of piezoelectric materials

This paper presents an overview of crack problems and numerical analysis of piezoelectric materials. Developments in Green‘s function, Crack problem, finite element, and boundary element formulation of piezoelectric materials are described. Finally, a brief summary of the approaches discussed is provided and future trends in this field are identified.

Economic Analysis of Bisphosphonate Use after Distal Radius Fracture for Prevention of Hip Fracture

Background: Osteoporosis is a common condition among the elderly population, and is associated with an increased risk of fracture. One of the most common fragility fractures involve the distal radius, and are associated with risk of subsequent fragility fracture. Early treatment with bisphosphonates has been suggested to decrease the population hip fracture burden. However, there have been no p...

Three-Dimensional Interfacial Green’s Function for Exponentially Graded Transversely Isotropic Bi-Materials

By virtue of a complete set of two displacement potentials, an analytical derivation of the elastostatic Green’s functions of an exponentially graded transversely isotropic bi-material full-space was presented. Three-dimensional point-load Green’s functions for stresses and displacements were given in line-integral representations. The formulation included a complete set of transformed stress-p...
