✦ Synopsis

A formulation is presented for the assessment of the reliability of a ship hull with respect to fatigue failure of the longitudinal members. The model allows for the existence of multiple cracks both in the stiffeners and in the plating and it models the crack growth process. The effect of the cracks in decreasing the midship section modulus is quantified as a function of time and the resulting reliability is quantified. The sensitivity of the reliability estimates with respect to several parameters is also studied.

Damping effects, the basic energy-loss mechanisms in practical structures, are seldom fully understood. Consequently it is not usually feasible to determine the damping coefficient by means of the corresponding generalized damping expression. For this reason the damping in most structural systems mu
