Abstract EN
With comprehensive application of the theories of coating shear failure mechanism and fatigue cumulative damage, a life prediction method of a gun barrel is proposed based on the shear fatigue damage accumulation at the coating-substrate interface.
The life of a small-caliber gun barrel is predicted by use of constant tensile strength at normal temperature and temperature-dependent tensile strength, respectively.
The influence of the two kinds of tensile strength on barrel life prediction results is analyzed.
Life test proves that the prediction method proposed here is credible and practical.
The research results show that the reduction of interface tensile strength due to temperature rise in the firing process is an important inducement of interface damage and gun barrel failure.
When the temperature-dependent tensile strength is considered in life prediction model, the prediction results are smaller than that predicted by use of constant tensile strength and well matched with the life test results.
Therefore, the temperature-dependent tensile strength should be incorporated in the model of gun barrel life prediction.
