The purpose of ensuring the reliability and safety of tilted functional materials and the consideration of microscopic structures are the basis for research on the strength of tilted functional materials. As a result of the research, the tilted composition of the site and the strength of the tilted functional materials were analyzed, and a method was proposed. The microscopic structure has been considered and the strength of the tilted functional material has been analyzed, and the analysis of the direction of the tilted functional composition of the change has been successful. Numerical value analysis techniques are used for research, homogenization methods are used for physical property evaluation, and good results are obtained.
