3D-DIC Analysis in Compression Test of Glass Tube

User Benefits

- The HPV-X3 high-speed video camera has resolution three times higher than the conventional device, resulting in improved analysis performance in DIC analyses. - The HPV-X3 high-speed video camera allows recording at a maximum framerate of 20 Mfps, two times faster than the conventional device. - Three-dimensional displacement measurement is possible by synchronous recording using two HPV-X3 high-speed video cameras and 3D-DIC analysis.

Introduction

Glass is used in various industries, such as electronic devices and automobiles. Depending on the intended application, mechanical properties are measured by material testing, but to achieve further improvements in performance, it is necessary to observe the origin of fracture and the condition of crack propagation. However, glass displays brittle fracture behavior, which is difficult to observe visually. In our previous reports, we observed the fracture behavior of glass specimens in ring-on-ring tests, and those observation results indicated that a high-speed video camera with a recording speed (framerate) of several Mfps or higher is required to observe the fracture behavior of glass. In this experiment, the fracture behavior of a glass tube during a compression test was observed with an HPV-X3 high-speed video camera. In addition, synchronous videorecording was carried out using two HPV-X3 cameras, and the strain distribution during fracture was visualized by a 3D-DIC (three-dimensional digital correlation) analysis.
