Short summary
A time-varying reliability model of parallel systems consisting of beams with crack flaws is developed, considering the dynamic interaction between stress correlation, crack extension correlation, strength degradation correlation, and the random load redistribution. The model can quantitatively analyze the effects of crack extension, strength degradation, load sharing, random load redistribution, and other factors on the time-varying system reliability.
