especially important where the number of tests may be small. These include physical tests but also many FEA simulations as well [Halfpenny (2019)]. The third plot (bottom left) shows the evolution of the reliability function with 90% confidence level. The fourth and last plot (bottom right) compares the probability density function (PDF) of the measured and simulated time to failures. The 1st Iteration:
