EXAMINATION OF THERMAL STRESSES OCCURRING IN CIRCULAR DISCS BY FINITE ELEMENT METHOD

Öz

In this study, thermal stress analysis on discs consisting of two different materials was analyzed analytically. Disc materials were selected SiC/6061 Al Alloy composite and Al-7075 respectively. Assuming that the elasticity module does not change with temperature, thermal stress analysis was performed under constant temperature distributions in the area from the inner surface of the disc to the outer surface. Thermal stress analysis was performed under constant temperature distribution. A computer program was developed for the calculation and the ANSYS finite element program was used. The values obtained from the analysis are presented in tables and graphs. There have been differences in radial and tangential stresses that occur because the elasticity modules and thermal expansion coefficients of the materials that make up the discs are different. The radial stress value has always been determined as zero on the innermost and outermost surfaces of the discs. Tangential stresses under constant temperature distribution from the inner surface to the outer surface occurred as pressure on the inner part of the disc and tensile stress on the outer part. It is concluded that the stresses occurring in the SiC /6061 Al alloy composite material are greater than those of AL-7075
