3. Theoretical Analysis
- The material properties are isotropic and independent of the temperature.
- The contact pressure is uniformly distributed over all the friction surfaces.
- The convective heat-transfer coefficient varies linearly with the speed.
- Radiation is neglected because of the short launching time.
- The wear on the contact surface is negligible.
