Identification of Anisotropic Elastic Material Properties by Direct Mechanical Simulations: Estimation of Process Chain Resource Requirements

Abstract

In this work the effort necessary, to derive a linear elastic, inhomogeneous, anisotropic material model for cancellous bone from micro computer tomographic data via direct mechanical simulations, is analyzed. First a short introduction to the background of biomechanical simulations of bone-implant-systems is given along with some theoretical background about the direct mechanics approach. The implementations of the single parts of the simulation process chain are presented and analyzed with respect to their resource requirements in terms of CPU time and amount of I/O-data per core and second. As the result of this work the data from the analysis of the single implementations are collected and from test cases, the data were derived from, they are extrapolated to an application of the technique to a complete human femur.
