The prediction of the ductility limit of sheet metals during forming processes represents nowadays and ambitious challenge. To reach this goal, a new numerical approach, based on the loss of ellipticity criterion [1], is ... -
Article dans une revue avec comité de lecture; ;MERAGHNI, Fodil (SAGE Publications, 2020)
In this work, a multi-scale model established from the concept of periodic homogenization is utilized to predict the cyclic and time-dependent response of thermoplastic-based woven composites. The macroscopic behaviour of ...
