Until 1transverse microcracking development is observed. About Contact Editorial Board Advanced Modeling and Simulation in Engineering Sciences welcomes submissions to the new thematic series on Model order reduction: POD, PGD and reduced bases This thematic series groups selected reserach contributions on Model Order Reduction, a new paradigm in the field of simulation-based engineering sciences, and one that can tackle the challenges and leverage the opportunities of modern ICT technologies. The main assumption is that the behavior of any laminate under any loading up to final fracture can be described using two elementary entities: the ply and the interface. Among them are those related to high-dimensional problems, problems involving very different time scales, models defined in degenerate domains with at least one of the characteristic dimensions much smaller than the others, model requiring real-time simulation, and parametric models. The description of the interaction between delamination and transverse microcracking is a rather ancient question in micromechanics [ 13141516171819202122 ]. Eng Fracture Mech77 4 —

    Classical interface damage evolution laws are retained because their identification relies on standard delamination tests. A new and relatively simple interface mesomodel taking into account the coupling with microcracking in the adjacent plies has been derived from the description of the damage scenarios on the microscale.

    Both transverse intraply cracks and delamination cracks are described in detail; thus, the competition between the two mechanisms can be modeled directly.

    This difference of behavior leads to different failure mode: the new model predicts a delamination dominated failure matching the experimental observations, the second model predicts a delayed failure due to fiber breaking.

    Methods Here, in order to model the interaction of intralaminar and interlaminar degradations, we develop a new and relatively simple micromechanics-based interface mesomodel which differs from classical cohesive interface models, since it includes the coupling between transverse intraply cracks and interface delamination.

    It was shown that the mesodamage of the interface depends only on the interface itself and on the microcracking rates of the adjacent plies [ 29 ]. Classical tests suffice to enable the identification of the material constants.

    These problems are of different nature, but are common to many branches of science and engineering. Chen WH, Yang SH: Multilayer hybrid-stress finite element analysis of composite laminates with delamination cracks originating from transverse cracking. The ones related to the interfaces are assumed to be the same. For example, in works such as [ 2627 ], classical cohesive interfaces are used for both transverse cracks and delaminations; in this case, however, a priori information about the cracking pattern e.

    2. Moreover, the enhanced interface model proposed in this paper bring a real improvement in the damage prediction compared to the former model used previously as in [ 12 ].

    3. The resulting enhanced mesomodel ply and interface is a computational model which is suitable for virtual testing. Download PDF.
