These structures have non-uniform composition, features, or spatial distribution. High-temperature structural components and thermal barrier materials have been investigated for FGMs in aerospace engineering. Their design has also been utilised in high-speed aeronautical vehicles. This work predicts the dynamic response of inhomogeneous beams by studying structural factors' mechanical behaviour. Structures with inhomogeneity, such as fractures and segment locations, must behave reliably non many engineering applications. The study methodically examines how inhomogeneity, crack depth, and segment position affect fundamental frequency and resonance amplitude. The results indicate if that specific segment with lower infill density is far away from the beam's fixed end, the natural frequency results are higher. An empirical model with 0.96 R-square value was developed to estimate the fundamental frequency for the beam with local inhomogeneity and was validated.67enHeterogeneousInhomogeneousDynamic Response3D PrintingFundamental FrequencyResonance AmplitudeCantilever BeamThesis
