Finite element analysis (FEA) has become a powerful alternative to experimental methods for investigating the pressure-dependent behavior of nanomaterials, offering high accuracy with reduced cost and complexity. In this work, a three-dimensional finite element model is developed to analyze and optimize the mechanical response of Fe2O3 nanomaterials under applied mechanical pressure. A cubic Fe2O3 crystal with dimensions of 100 nm 100 nm 100 nm is modeled, incorporating realistic material properties, boundary conditions, and mesh refinement strategies. Mechanical pressure ranging from 0 to 16 GPa is applied to evaluate volume ratio variation, stress distribution, and displacement characteristics. The results reveal a monotonic reduction in volume ratio with increasing pressure, indicating elastic compression and high structural stability. Stress analysis shows non-uniform distribution with localized concentration near boundary regions, while displacement remains minimal even at high pressure levels, confirming the stiffness of Fe2O3. Mesh convergence studies validate the numerical accuracy of the model. The optimized FEM results demonstrate close agreement with theoretical predictions and reported experimental trends, confirming the reliability of the simulation framework. This study highlights the effectiveness of FEM-based optimization for predicting pressure-dependent mechanical behavior of Fe2O3 nanomaterials and provides valuable insights for their application in pressure sensors, NEMS devices, and mechanically robust nano-scale system. |
