Numerical analysis of bovine trabecular bone by using physiological loads specific to normal walking loads and down stairs loads

Abstract

This project is containing of simulation on sectioned Bovine Trabecular Bone. The Bone was extracted from fresh bovine bone with interested section dimension for about 2 × 2 × 3.5 mm. After scanned process through µCT scanner, the bone was constructed via Mimics software. With preferred size of elements and consumed time per simulation, 774,996 elements were selected meshing number to use. Combination of 3 axes loads for both physiological movement specific to normal walking loads and downstairs loads, those presented one minute trends cycle completed both cycle as reliable applying loads in the consequent Trabecular Bone model. Simulation was conducted by fixed the model at the bottom and applying gait loads at the top, revealed most deflection of Trabecular Bone were occurred while down stairs activities. The most stress entire simulation also weighed to down stairs activities. From that, it composes young modulus for normal walking is 14.8Gpa. In the other hand, downstairs activities complies 14.9Gpa. Deviation on the experimental data of compressive test, could be translate on different of density model, besides, by doing only compressive stress could not represent on physiological loads on actual real situation.
