Bone young's modulus

WebYoung’s Modulus Young’s modulus, also known as elastic modulus, is used to measure the ability of a solid material to endure changes in length while under lengthwise tension or compression. This helps to provide a numerical value to describe a material’s mechanical properties. It is expressed by the following equation: Young’s Modulus ... WebSince there are many muscles in the body, each tendon differs in its function and therefore its mechanical properties. For example, the Young’s modulus of the human patellar tendon is 660 ± 266 MPa (mean ± …
