Conference Paper Description

Bone is a composite structure that behaves as anisotropic material and consists of a hierarchical structure due to which the properties of bone changes with each level. It consists of moisture content, protein, porosity, etc. due to which the bone properties vary with age, weight, composition, etc. Several studies have been conducted to find out the mechanical properties of cortical bone at different levels. Several specimen shapes and sizes have been used to conduct an experimental study. In case, a specimen shape has been chosen that is more difficult to fabricate and to perform the test; it becomes a very tough task for a researcher. Therefore, specimen designing becomes an important requirement in performing experimental tests on cortical bone. Taking this objective into consideration, a current study has been conducted to compare the effectiveness of three different specimen shapes that are used to perform compressive tests on the universal testing machine using FEM. The total deformation and Von- Misses stress of each specimen have been evaluated and compared with the existing literature. It has been found that a cube-shaped specimen is the best option to conduct a compressive test on cortical bone followed by cylindrical and rectangular specimen shapes. The results obtained in the current study have been validated with the existing literature and found a good correlation.
