This happens if there is an “aging” process, or parts that are more likely to fail as time goes on. An example would be products with a built-in weakness that fail soon after the warranty expires. In the field of materials science, the shape parameter k of a distribution of strengths...
Example 18.12 A batch of some critical components (such as turbine blades) were manufactured. Assuming that the distribution is a Weibull distribution with a characteristic stress σ0=240 MPa, a shape parameter n=6 and V=V0, what is the service stress that can be applied so as to ensure ...
The Weibull distribution is a continuous probability distribution used for finding failure rates. Visit BYJU’S page to learn the standard parameterization formulas and plot.
In this example, the Weibull hazard rate increases with age (a reasonable assumption). Compute the hazard function for the Weibull distribution with the scale parameter value 1 and the shape parameter value 2. Get t = 0:0.1:4.5; h1 = wblpdf(t,1,2)./(1-wblcdf(t,1,2)); Compute ...
