Laminated Composite Materials

The durability and residual load carrying capacity of composite materials and structures is of critical importance for increasing their application across the industry. Regularized eXtended Finite Element Method (Rx-FEM) framework for discrete modeling of damage evolution and interaction in laminated composite materials under fatigue loading has been extended to include residual Strength Tracking (ST) method in the Mesh Independent Crack (MIC) insertion constitutive modeling as well as in the initiation phase of the fatigue Cohesive Zone Model (CZM). The ST method was initially proposed for semi empirical analysis of IM7/8852 open-hole specimen test S-N data under spectrum loading and variable R -ratios (R = 0.1, 5, and -1). In the present work, the ST method is implemented as a component of high-fidelity progressive damage analysis framework and is combined with damage variable incremental update technique for the propagation phase within the CZM formulation. 3D validation examples investigating the solution stability under constant amplitude fatigue with respect to the cycle increment size are presented and demonstrate the solution stability within a feasible range of cycles per step.

The main purpose of this research is to select suitable matrices and fillers for the preparation of composites that meet modern requirements to meet the needs of a rapidly growing industry. Studies in various databases have shown that metal-matrix hybrid laminated composite materials, mainly aluminum and magnesium alloy plates, are used as matrix materials, while carbon-based nanomaterials are used as fillers. Keywords: composition, matrix, aluminum, magnesium.
