An in-house Approach for Assigning Bone Material Properties of Finite Element Models Applied in ABAQUS

Abstract

Strategy of assignment influences the accuracy of CT-image based bone material properties of finite element model. An in-house assigning package was produced and compared the predicted results (stress and strain) with Bonemat 3.2 using a validated TCVO finite element model in physiological loading condition. The stress had local consistency and much variability was addressed including the strain prediction. May be different algorithms between assigning packages was the reason. Optimizing the algorithm and more tests are needed further to improve the accuracy of assigning bone material properties for ABAQUS users.
