Experimental Study on Failure Mechanism of Hierarchical Corrugated Structures with Second-order Core
IOP Conference Series: Earth and Environmental Science(2020)
Abstract
Abstract Based on the sample experiment and ANSYS simulation, the experimental verification of the failure mode prediction model under compression load is completed, and the experimental results are compared with the theoretical analysis results. Among them, the sample experiment is carried out on the universal testing machine, including base metal experiment and uniaxial compression experiment. The experimental model is made of UV Curable Resin by 3D printing technology. And the buckling mode numerical simulation is completed on the ANSYS Workbench, using the plate and shell model of the pumping surface. By comparing the failure mode and yield stress of theory, experiment and simulation, the results show that the accuracy of the prediction model based on plate theory is higher. It can provide theoretical reference for structural design.
