PREFACEAbout seven months ago, I was introduced to computational modeling of composite laminates. At that time, a poster that presented the work of Bert Sluys and Frans van der Meer caught my eye. I did not realize that this was going to be the basis of my master thesis! I'm very thankful that I've had to chance to work with Bert and Frans and that they have guided me through my final project. After a course in C++ and Jem Jive and a lot of hard work, the composite laminate failure model resulted that I describe in this thesis. To accompany it, I wrote a paper summarizing my findings, something I'm very excited about. As challenging as the computational modeling of composite laminates was, being able to explain what I spent my days doing to my friends and family was equally as difficult. I hope with this paper and my presentation I can make it clear to them.

“…In composite failure analysis, another class of methods, the phantom node method (PNM) [13][14][15][16][17][18] and the augmented finite-element method (A-FEM) [19][20][21], are more widely used. These methods are derived from the seminal work of Hansbo & Hansbo [22] and further developed in [13,14].…”

“…These methods are derived from the seminal work of Hansbo & Hansbo [22] and further developed in [13,14]. Other emerging methods for composite failure analyses include the regularized FEM (RxFEM) of Iarve et al [23,24] and the continuum-decohesion FEM by Waas and co-workers [25].…”

In this paper, a thermal-mechanical augmented finiteelement method (TM-AFEM) has been proposed, implemented and validated for steady-state and transient, coupled thermal-mechanical analyses of complex materials with explicit consideration of arbitrary evolving cracks. The method permits the derivation of explicit, fully condensed thermalmechanical equilibrium equations which are of mathematical exactness in the piece-wise linear sense. The method has been implemented with a 4-node quadrilateral two-dimensional (2D) element and a 4-node tetrahedron three-dimensional (3D) element. It has been demonstrated, through several numerical examples that the new TM-AFEM can provide significantly improved numerical accuracy and efficiency when dealing with crack propagation problems in 2D and 3D solids under coupled thermalmechanical loading conditions.

The failure of carbon fiber reinforced epoxy laminates is studied using an anisotropic gradient-enhanced continuum damage model embedded in a mean-field homogenization scheme. In each ply, a homogenized material law is used to capture the intra-laminar failure. The anisotropy of the homogenized material model results from the homogenization method and from the reformulation of the non-local continuum damage theory to account for the material anisotropy. As a result the damage propagation direction in each ply is predicted with accuracy as compared to the experimental results, while the problems of losing uniqueness and strain localization, which occur in classical finite element simulations when strain softening of materials is involved, can be avoided. To model the delamination process, the hybrid discontinuous Galerkin/extrinsic cohesive law method is introduced at the ply interfaces. This hybrid method avoids the need to propagate topological changes in the mesh with the propagation of the delamination while it preserves the consistency and stability in the un-cracked interfaces. As a demonstration, open-hole coupons with different stacking sequences are studied numerically and experimentally. Both the intra-and inter-laminar failure patterns are shown to be well captured by the computational framework.
