The aim of this study was to compare the results obtained using the piecewise nonlinear model with those of a modular network (MN) architecture in modelling fatigue behaviour. We used a database consisting of ten materials derived from the literature and represented by the following acronyms: C10, C12, DD16, HTA‐913, IM7–977, MAT(0) 2 , T800–5245, T800H‐3631, QQ1 and QQ1T. The results obtained by MN were compared with those of the PNL. The results for both the PNL and MN model were satisfactory for the fatigue behaviour of glass fiber‐based composite materials, but for carbon fiber‐based composites only MN showed satisfactory results.
