| Abstract: | A simplified model is founded in order to simulate the temperature fields of multi layer gun barrels of composite materials according to the firing under a controlled schedule Based on a finite difference technique for transient heat conduction,the difference equations of interface, surface and inner node are given, also with the computation results The conclusions obtained are valuable to improve the service life of gun barrels, and they offer scientific basis for the rational and effective choice of materials |
| Keywords: | finite difference gun barrel temperature field |
