The Poisson’s ratio, bulk modulus, Young’s modulus and modulus of rigidity are the elastic moduli that are frequently employed in engineering practice. In the industrial world, elastic data are utilised to assess material strength. When considering the polycrystalline material (such as spinel ferrites, superconduc- tors, perovskites and garnets) expose to mechanical stresses, information of the material’s magnetic, electric, elastic and dielectric properties aid in finding the material’s suitability for a given application. From the perspective of funda- mental research, understanding elastic moduli clarifies the nature of forces (i.e interatomic and interionic) in the nanomaterial. Studies on a material’s elasticity play a significant role because they are crucial for determining the strength of its binding force. The computation of elastic moduli plays a very important role in overcoming physical stresses especially in material fabrica- tion and its industrial use. The present review focuses on the determination of elastic modulli using X-ray diffractometry and infrared spectroscopy.
