The present research deals with the concept of finite strain theory, offering a very innovative perspective by introducing a novel Equation of State (EOS). The newly proposed EOS derives from an unconventional approach, by expanding the difference in 7/2th power expansion of the edge length of a symmetrical cube under continuous applied pressure. The study primarily focuses on evaluating the applicability of this new EOS within the domain of nanomaterials. The investigation involves a comprehensive review of finite strain theory concepts, laying the groundwork for the development of this new EOS. To validate its efficacy, rigorous comparisons are made between experimental data and existing theoretical frameworks, specifically targeting high-pressure conditions pertinent to nanomaterials.
