title: A new dynamic device for low-dimensional materials testing.
abstract: As the geometrical size of low-dimensional materials decreases to micro- or nanoscale, the traditional dynamic loading system cannot be used anymore to measure the dynamic mechanical property. In this study, a new dynamic loading system was developed. A piezoelectric transducer actuator was used for displacement loading, and a mechanical lever was designed to amplify the displacement load. Finite element method simulation and validation experiments were conducted to analyze the strength and function of the mechanical lever. As an application test, a sample from an aluminum film was investigated using the system. The success of the experiment, as shown by the results, demonstrated the feasibility of the system for low-dimensional materials study.
