基于霍普金森压杆系统的动态压痕实验
Dynamic indentation experiment based on the split-Hopkinson pressure bar system
摘要
Abstract
A new technology for testing dynamic properties of materials was proposed by developing an experimental setup based on a split-Hopkinson pressure bar system. The experimental setup can be used in dynamic indentation experiments to obtain the indentation displacements of materials and the impact load suffered by them. To validate the experimental setup, the ABAQUS/Explicit FE code was used to numerically simulate dynamic indentation experiments. Dynamic indentation experiments were conducted on aluminum alloy LY12, pure titanium and oxygen-free copper. The dynamic properties such as dynamic hardness and rate sensitivity were obtained for these three kinds of materials. The dynamic properties obtained by dynamic indentation experiments are consistent with those by other experimental methods.关键词
