elastic modulus is simply defined as the ratio of stress to strain within the proportional limit. physically, it represents the stiffness of a material within the elastic range when tensile or compressive load are applied. it is clinically important because it indicates the selected biomaterial has similar deformable properties with the material it is going to replace. these force-bearing materials require high elastic modulus with low deflection. as the elastic modulus of material increases fracture resistance decreases. it is desirable that the biomaterial elastic modulus is similar to bone. this is because if it is more than bone elastic modulus then load is born by material only; while the load is bear by bone only if it is less than bone material. the elastic modulus of a material is generally calculated by bending test because deflection can be easily measured in this case as compared to very small elongation in compressive or tensile load. however, biomaterials (for bone replacement) are usually porous and the sizes of the samples are small. therefore, nanoindentation test is used to determine the elastic modulus of these materials. this method has high precision and convenient for micro scale samples. another method of elastic modulus measurement is non-destructive method. it is also clinically very good method because of its simplicity and repeatability since materials are not destroyed.
