ABSTRACT

The purpose of the work done is to propose a numerical model for the analysis of the fatigue behaviour of marine structures made of composite laminates. In order to achieve it, two formulations are used to obtain the fatigue performance. The serial/parallel mixing theory [1] which is a constitutive law manager and a fatigue damage model [2].

Besides, a calibration methodology has been proposed to obtain the material parameters from the fibre and matrix, both static and fatigue characterization.

The formulation is applied on several types of laminates, as balanced angle ply laminates, comparing the numerical results with the experimental results, obtaining the failure mode and number of cycles to fail.
