| Summary: | This study examined functionally graded foam beam thermal buckling. The functionally graded beam was made of biocompatible Ti6Al4V metal (bottom surface) and ceramic zirconia (top surface), which changed function with thickness. Three types of foam structures were assumed along the functionally graded beam's thickness to imitate bone structures. symmetric and homogeneous foam structures feature open-cell foam void ratios up to 60%. Using the Hamilton principle and higher-order beam theory, equations of motion were generated and solved using the Navier technique. The impacts of ceramic and metal materials, foam structure type, and foam void ratio on FGM beam thermal buckling were examined and presented. The uniform foam distribution model (Model 1) has the highest buckling temperatures. Additionally, raising foam void ratio increased thermal resistance in all models. Beams with greater titanium content had higher buckling temperatures. |
