Abstract

In this paper, a new method was proposed to measure the material characteristic parameter. Young's modulus and thermal expansion coefficient can be measured with FBG attached on the sample. The principle of measuring the material characteristic parameter was expatiated, a tiny thermal expansion coefficient was measured experimentally. This method is very convenient and precise, moreover, which can measure infinitesimal and negative thermal expansion coefficients, but existing methods are difficult to do it.
