Resumen
This paper analyzes the behavior of a functionnally graded plate subjected to impact force at a low velocity by adopting the Hertz law. The differential equation which governs the impact phenomenon is used to calculate the contact force, indentation and indentation velocity. Elastic properties of the FGM plate are obtained by integration of the components volume fraction across the thickness. A parametric study is conducted to evaluate effects of temperature, the power law index, the projectile mass on the contact force and indentation. The results obtained are compared to those in the literature for other structures.
