Balancing flexural strength and porosity in DLP-3D printing Al2O3 cores for hollow turbine blades
Journal of Materials Science & Technology, 2021High porosity and high strength are usually mutually exclusive in the preparation of ceramic materials. However, high porosity and flexural strength are required for the preparation of complex ceramic cores for hollow turbine blades. In this study, Al2O3

Review of Scientific Instruments, 2023
This paper proposes a new type of flexure hinge: the sinc flexure hinge. A theoretical compliance and precision factor model of the sinc flexure hinge is developed based on the transfer matrix method. The finite element simulation is carried out using ANSYS Workbench. The error between the modeling and simulation results obtained is less than 7.0%. The
