Mechanical Behaviors of Ultra-high Temperature Ceramics

摘要：

　　The parameters,such as thermal expansion coefficient and Youngs modulus,are considered as a function of temperature and incorporated into ANSYS code to calculate the stress field of UHTCs under high temperature condition in the present work.The stress fields of two kinds of heating cases are calculated and compared.By establishing the relation between the temperature and the mechanical properties of the UHTCs,it is found that the mechanical behavior of UHTCs is strongly affected by the oxide film thickness,initial temperature and the heating rate.
