Abstract
The goal of this work is to assessing the life of the composite material. This research is subdivided in two parts: The first part is to compare the results found using numerical simulation with those obtained experimentally by alternating traction tests. In this study we used the ANSYS to validate the experimental results and evaluate the life of the unidirectional composite glass / epoxy under constant amplitude loading. The numerical results of these tests were also able to trace the curve of Wöhler using the criterion of life which corresponds to a total rupture of the specimen. This curve shows a dispersion of life in the case of trials. The second part presents the numerical results of life simulation of this material under block loading variable amplitude in three stress level cases.
