Abstract

Aim To study the critical crack and initial permissible crack size of gun tube. Methods According to fracture machanics theory

a mathematical model for critical crack of gun tubes and initial permissible crack size was developed. Results Using the established mathematical model

with some data of an antiaircraft tubes

critical crack and initial permissible crack size of the antiaircraft gun tube were worked out. Conclusion Through theoretical analysis and practical example

the importance of controlling the crack formation is shown in the process of making gun tube.
