Abstract

This study is containing of simulation on sectioned bovine trabecular bone. The aim of this research is to determine the prediction of the compressive fatigue behavior on cancellous bone specimens as a function of density, porosity and volume fraction. The specimen was extracted from fresh bovine bone with interested section dimension for about 2 × 2 × 3.5 mm. After scanned process through µCT, the bone was constructed using Mimics. With preferred size of elements and consumed time per simulation, optimum meshing yield 774,996 elements number was used. Combination of 3 axes loads for both physiological movements specific to normal walking and downstairs presented as one minute trends cycle completed during stance phase was applied on trabecular bone 3D model. Simulation was conducted with the bottom of the model fixed while gait loads applied at the top. Most deflection with highest stress occurred during downstairs simulated condition. Young modulus for normal walking and downstairs loading condition are 14.8 GPa and 14.9 GPa respectively. Differences of the compressive experimental data compared to present result could be influenced by density model. Compressive stress alone could not represent any actual physiological loads during daily activities.
