Effect of Decalcification on the
Fracture Energy of Chicken Bone
Name: Ryan Goldstein
Class: BE 210
The primary goal of this experiment is to determine the effect of decalcification (reduced bone density) on the fracture energy of chicken bone via a three-point bending test. Additionally, a qualitative relationship will be developed between decalcification and fracture energy (does fracture energy decrease with increased decalcification?). It is hypothesized that the fracture energy of non-decalcified bone will be significantly greater than that of decalcified bone, and that fracture energy will decrease as amount of decalcification increases.
Secondary goals consist of properly obtaining data to be used in calculations in order to derive significant and meaningful results, familiarization with a decalcification technique, and understanding the importance of hydroxyapatite on the material properties of bone.
A. Experimental Goals:
1. To determine the effect of decalcification (reduced bone density) on the fracture energy of bone using a three-point bending test.
2. To attempt to develop a qualitative relationship between relative amount of decalcification and fracture energy.
B. Educational Goals:
1. To reinforce the process of obtaining data used in calculations to derive significant and meaningful results.
2. To become familiar with a bone decalcification technique.
3. To emphasize the importance of hydroxyapatite mineral crystals in bone strength.
