A new technique in the strength reliability evaluation and design simulation of the ceramic mechanical components

When ceramic strength evaluation was done, it was shown that the evaluation of the effective volume was important. Then, a problem in the calculation of the effective volume was shown. An error of the usual method which calculate the effective volume by using the algorithm of the volume integral calculus of finite element method became very large. It considers that an error becomes big because power index of the integral function becomes very large when effective volume is calculated. Three new techniques were proposed to solve this problem. These three proposed methods show near value with the theory answer.
