Revealing complex aspects of compressive failure of polymer composites - Part II: Failure interactions in multidirectional laminates and validation

With this approach, the progressive failure of multidirectional laminates under compressive loading can be simulated in detail considering the complete kinking process and the progression of kink bands. The sequence and interaction of the different failure mechanisms is studied and discussed. In order to validate the numerical results, the nonlinear stress-strain response and ultimate failure stress of selected carbon epoxy laminate layups is predicted and compared with experimental results.
