고기능성 소재용 마이크로 인장시험기 개발

Abstract

Micro tensile test is the most direct and convenient method to measure material properties such as Young's modulus and fracture strength. It, however, needs more accurate measurement system, more stable and repetitive alignment and more sensitive gripping than conventional tensile test. Many researchers have put their effort on overcoming these difficulties for the development of micro tensile tester, fabricating micro specimens of functional materials and measuring their properties. This paper will review the related vigorous researches over the world in the recent decade and explain how to apply them to a design of the tester which is under our own development.
