Abstract
In order to proper evaluate mechanical behavior of tapered composite structures a new framework of analysis is proposed based on the theory of failure by Alfred Puck, implemented on an 3D XFEM routine. A new optimization algorithm is proposed in order to determine the initial onset crack angle. After extensive validation against literature results and experiments built specifically for capturing the mechanisms of interest, the model was found to be robust, capable of correctly reproducing ultimate load and more than 20 times more efficient than current implementations
