High Temperature Design Criteria of Cordierite Ceramic Substrate in Four-point Banding
4점 굽힘시험에서 코디어라이트 세라믹 담체의 고온설계기준
Abstract
The four-point bending test is a widely used method to determine material parameters. The aim of the present study was to evaluate the flexural strength (or modulus of rupture) and the Weibull modulus of cordierite ceramic substrate by means of four-point bending tests. The strength data from experiments followed Weibull statistics. These data indicate that the fatigue effects are more severe when the substrate temperature in the peripheral region is near
