| Abstract | ||
| This study pioneers the analysis of low-velocity impact behavior in spinning functionally graded porous circular plates reinforced with graphene platelets (GPLs), employing first-order shear deformation theory. The governing equations are derived via Hamilton's principle, while the plate-impactor interaction is modeled using a modified Hertzian contact law. Numerical solutions are validated against existing literature showing excellent agreement. Parametric studies investigate the effects of:(1) Spinning speed (revealing that higher speeds increase contact force but reduce impact displacement), (2) Porosity characteristics (distribution patterns and coefficients), (3) GPL reinforcement configurations, and (4) Nanofiller weight fractions on the dynamic response. Results highlight that porosity distribution has the most pronounced influence on both contact force evolution and transient centerpoint deflection, outweighing other variables. | ||
