Özet: This study deals with investigation of effects of cross sections and ceramic materials on the fundamental vibration behavior of beams. Fundamental frequency analyses were performed using finite element software ANSYS based on Taguchi’s L8 orthogonal array with two control factors. Ceramic material types were used as the first control factor consisting of four levels such as Zirconia (ZrO2), Silicon nitride (Si3N4), Alumina (Al2O3), and Silicon carbide (SiC) while cross-sections of beams were considered as the second control factor including two levels such as triangle and hexagon. To optimize the ceramic materials and cross sections, analysis of signal-to-noise (S/N) ratio was used. Important control factors and their percent contributions on numerical fundamental free vibration response were performed using analysis of variance (ANOVA).
