Abstract:
A study is made of the dependence of the time of propagation of a fracture front in thick-walled vessels subjected to internal pressure on the wall thickness and the employed version of kinetic theory of creep. The stress intensity is taken to be the equivalent stress. Recommendations on using the results in computational applications are formulated.
Keywords:creep, damage parameter, fracture onset time, pressurized vessels, fracture front propagation.
