000015140 520__ $$2eng$$aWe propose a new and computationally efficient continuum damage based model that is able to predict the compressive response in the fibre direction. Instead of invoking the geometric instability into the material model, a key feature is to consider the geometrical fibre kinking instability on the macro-level based on a finite strain formulation. To represent the proper energy dissipation, an elastic damage model is formulated in the invariants of fibre shear and fibre compression. As opposed to the rotating crack modeling commonly used for this problem, we propose a different approach to the UD–ply fracture based on continuum gradient damage, cf. [1]. Two models are defined; one model based on the non–local continuum damage theory and another local one, cf. ref. [2]. The numerical results indicate the predictive capabilities of the modeling.
