Abstract
accommodate the hierarchical structure of bone. This hierarchical-HCA methodology utilizes communication between continuum level and tissue level models of bone to guide the remodeling process. The HCA algorithm utilizes the average apparent density of the tissue level structures to update the stiffness characteristics of the continuum model of bone. In this research, a method for calculating the local anisotropic properties of these structures is developed. This approach utilizes confined uni-axial strain tests, on each tissue level model, to numerically determine the structure's stiffness tensor. The objective of this work is to increase the fidelity and versatility of the hierarchical-HCA algorithm by assimilating the computed mechanical properties of the tissue level models. Preliminary analyses display improved efficiency and a more consistent material distribution when incorporating the anisotropic properties into this methodology.

Abstract The internal bone adaptation of the proximal femur is considered. A three-dimensional finite element model of the proximal femur is used. The bone remodeling in this work is numerically described by an evolutionary remodeling scheme with anisotropic material parameters and time-dependent loading. The memory of past loading is included in the model to account for the delay in the bone response from the load changes. The remodeling rate equation is derived from the structural optimization...

Abstract Over 100 years ago, Wolff hypothesized that cancellous bone altered both its apparent density and trabecular orientation in response to mechanical loads. A mathematical counterpart of this principle is derived by adding a remodeling rule for the rate-of-change of the full anisotropic stiffness tensor (all 21 independent terms) to the density rate-of-change rule adapted from an existing isotropic theory. As a result, anisotropy and density patterns develop such that the local stiffness t...

A method is presented to find orthotropic elastic symmetries and constants directly from the elastic coefficients in the overall stiffness matrix of trabecular bone test specimens. Contrary to earlier developed techniques, this method does not require pure orthotropic behavior or additional fabric measurements. The method uses high-resolution computer reconstructions of trabecular bone specimens as input for large-scale FE-analyses to determine all the 21 elastic coefficients in the overall stif...

The process of adaptive bone remodeling can be described mathematically and simulated in a computer model, integrated with the finite element method. In the model discussed here, cortical and trabecular bone are described as continuous materials with variable density. The remodeling rule applied to simulate the remodeling process in each element individually is, in fact, an objective function for an optimization process, relative to the external load. Its purpose is to obtain a constant, preset ...

Abstraet. Composite material elastic behavior has been studied using many approaches, all of which are based on the concept of a Representative Volume Element (RVE). Most methods accurately estimate effective elastic properties when the ratio of the RVE size to the global structural dimensions, denoted here as ~/, goes to zero. However, many composites are loeally periodic with finite q. The purpose of this paper was to compare homogenization and standard mechanics RVE based analyses for periodi...

Aha& strain. At this time, however, there is no generally accepted (or easily accomplished) technique for predicting the effect of microstructure on trabecular bone apparent stiffness and strength or estimating tissue level stress or strain. In this paper, a recently developed mechanics theory specifically designed to analyze microstructured materials, called the homogenization theory, is presented and applied to analyze trabecular bone mechanics. Using the homogenization theory it is possible t...

Abstract The skeleton consists of a series of elements with a variety of functions. In locations where shape or protection are of prime importance the bone's architecture is achieved during growth under direct genetic control. In locations where resistance to repetitive loading is important only the general form of the bone will be achieved as a result of growth alone, the remaining characteristics result from functional adaptation. This mechanism ensures that bone architecture is modelled and r...

The subject of this article is the development and application of computer-simulation methods to predict stress-related adaptive bone remodeling, in accordance with 鈥榃olff's Law鈥. These models are based on the Finite Element Method (FEM) in combination with numerical formulations of adaptive bone-remodeling theories. In the adaptive remodeling models presented, the Strain Energy Density (SED) is used as a feed-back control variable to determine shape or bone density adaptations to alternative fu...

With the increased use of improvised explosive devices in regions at war, the threat to military and civilian life has risen. Cabin penetration and gross acceleration are the primary threats in an explosive event. Cabin penetration crushes occupants, damaging the lower body. Acceleration causes death at high magnitudes. This investigation develops a process of designing armour that simultaneously mitigates cabin penetration and acceleration. The hybrid cellular automaton (HCA) method of topology...

Structural design for crashworthiness is a challenging area of research due to large plastic deformations and complex interactions among diverse components of the vehicle. Previous research in this field primarily focused on energy absorbing structures that utilise a desired amount of material. These structures have been shown to absorb a large amount of the kinetic energy generated during the crash event; however, the large plastic strains experienced can lead to material failure and loss of st...

Design for structural topology optimization is a method of distributing material within a design domain of prescribed dimensions. This domain is discretized into a large number of elements in which the optimization algorithm removes, adds, or maintains the amount of material. The resulting structure maximizes a prescribed mechanical performance while satisfying functional and geometric constraints. Among di erent topology optimization algorithms, the hybrid cellular automaton (HCA) method has pr...

This work presents an application of the Hybrid Cellular Automaton (HCA) approach to the shape optimization of aluminum thin walled structures for blast mitigation. The design objective is to minimize the kinetic energy transferred from the blast event to the target. Fluid structure interaction between blast products and the target structure is considered as the driving factor in the blast mitigation problem. The method proposed couples an Arbitrary Lagrange Eulerian Fluid Structure Interaction ...
