Tensile and Compressive Test of Resin and Alumina Ceramic with Varying Sampling Rate - Influence of Sampling Speed on Strength Value

Introduction

Although many metal and resin materials exhibit plastic deformation behavior, glass and ceramic materials display virtually no plastic deformation and thus are subject to brittle failure. When obtaining the material strength of brittle materials by high-speed and short-time measurement, the value of strength and the data scatter may vary depending on the sampling speed of the testing machine. In this experiment, the effect of the sampling speed on measured strength values was confirmed by conducting strength tests of ceramic and resin samples and adjusting the sampling speed by data processing after the test.
