Abstract:

Maximum-entropy and asymptotic models for probability densities with application to the uncertain behavior of a structural component are considered. In particular, they are studied with the aim of describing the non-normal behavior of a function R(X) of random quantities, when a quadratic approximation to R is provided. Higher order moments involved in such models are evaluated through closed-form formulae derived from the analysis of a resulting standard quadratic form.
