Abstract
En 中文
This study delves into the intriguing realm of nonlinear responses exhibited by porous functionally graded (FG) 3D shell structure. A power law approach is formulated to simulate the mechanical behavior of FG materials, considering two distinct porosity distributions. This approach provides a comprehensive exploration of porosity phenomena in FG materials. The finite element (FE) formulation is based on an improved first-order shear deformation theory (FSDT) with the inclusion of thickness stretching parameters. The theoretical framework improved in this manner provides a more accurate representation of the transverse shear stress distribution within the structure, capturing the complexities of its behavior under loading conditions. This research enriches understanding of FG materials by integrating porosity that may be distributed evenly or unevenly, thus contributing to the advancements in the field.
