Application of Visual Basic (VB) Language on Stress Corrosion Cracking Test of Materials

Article Preview

Abstract:

With Visual Basic (VB) language programming, on the basis of traditional SSRT testing, and by the superimposition of square wave load with certain frequency, the stress corrosion test of tensile fluctuating load can be realized. SCC sensitivity of specimen superimposed with square wave load is weaker and its fracture is flat. Results show that VB language programming can accurately and effectively simulate the fluctuating stress state of pipeline caused by pressure fluctuation of natural gas in the stress corrosion test of materials, and can better study the rule and mechanism of stress corrosion of materials, so as to find the economic and effective protection method.
