Research on Mechanical Properties of Porous Structures Based on Triply Periodic Minimal Surfaces
To overcome the difficulty in directly predicting the mechanical properties in porous structure designing,this paper establishes a relationship model between the structural parameters and the mechanical properties of the Schwarz_P structure,by selecting the Schwarz_P surface in the triply periodic minimal surfaces,applying selective laser melting technology to manufacture the Schwarz_P structures with different structural parameters and conducting compression test for the study of Schwarz_P structures'mechanical properties.The test results show that the goodness of fit for the designed model is more than 98%,the mechanical properties predicted by the model are basically consistent with the measured values,and the mechanical properties can be intuitively predicted when designing porous structure.
