A closed-form analytical solution is developed for analyzing laminated composite curved beam with out-of-plane fiber waviness under bending. Timoshenko beam theory was adopted in derivation where the effects of shear deformation was considered for moderately thick beam. Explicit expressions for evaluating equivalent axial and bending stiffness are formulated based upon the modified lamination theory and taking the structural deformation characteristics of narrow section beam into consideration. Stress distribution at any given location calculated by the proposed method is investigated. Significant increase of radial normal stress and shear stresses are observed when out-of-plane fiber waviness is introduced. The comparisons between present analytical results and numerical data indicate that the present methodology have ability to capture radial normal, circumferential normal, and shear stress distributions of composite curved beam with out-of-plane fiber waviness and the level of stress predicted is satisfactory with numerical results.

“…This model has widely been used in the computational analysis of CFRP composites. [28,29] The macroscale finite element analysis (FEA) has been used to evaluate the fiber fragmentation mechanism of single fiber composite (SFC). [30] The CZM also is used to develop the mixed-mode damaging beamlattice model using the discrete element method.…”

A multiscale modeling framework is developed to investigate the effect of ZnO nanowires (NWs) on the fiber/matrix interface, and the fiber fragmentation mechanism of ZnO NW coated single fiber composites (SFC). Atomistic traction-separation analysis is conducted using molecular dynamics simulation technique to evaluate the interface properties between the functionalized carbon fiber surface and ZnO NW/polymer matrix. The results indicate that incorporating ZnO NW can significantly enhance interface stiffness, strength, and fracture energy. The results obtained in opening and sliding modes are implemented in the cohesive zone model to simulate the interface at the mesoscale. Microhomogenization analysis is performed on a representative volume element containing ZnO NW reinforced polymer matrix to determine the effective material properties of the enhancement layer. The interface and enhancement layer properties are imported into the macroscale hybrid SFC model. Single fiber fragmentation analysis is performed employing user material (UMAT) subroutine and ABAQUS finite element analysis package. Simulation results demonstrate that the load is transferred more efficiently from matrix to fiber in the hybrid than in the bare fiber model. The fiber fragmentation is increased in the hybrid composite structure, resulting in up to 100% improvement in interfacial shear strength of SFC incorporating ZnO NW.

“…Murri et al and Zhang et al developed analyses for the durability of tapered composite beams subjected to combined loads 8,9 . Liang et al demonstrated the ability of an extended finite element model to predict the ply migration of fatigue‐driven delaminations 10 . However, test cases where the delamination does not evolve in a self‐similar manner are often too complex both in terms of configuration, response, and failure modes to be used as a benchmark for the validation of numerical damage models focused on the propagation of delamination.…”

“…In addition, the model is easy to implement because it is purely local; that is, the damage at an integration point only depends on the accumulated history of the cyclic stresses. Liang 10 adopted the CF20 model to simulate a clamped tapered beam (CTB) subelement focusing on crack initiation and delamination migration. The innovative aspect of the present study is that it demonstrates that the evolution of a relatively complex delamination front can be predicted based on few independently characterized properties and without adjustments based on expected outcome.…”

This paper evaluates the capabilities of the recently developed CF20 cohesive fatigue model, which can predict crack initiation as well as the rates of crack propagation by relying on intrinsic relationships between a stress-life diagram and its corresponding Paris law. The model is validated here using a partially reinforced double cantilever beam (R-DCB) benchmark proposed in literature.The two parameters needed for the CF20 cohesive fatigue model were obtained by performing preliminary analyses of a conventional DCB. The analysis results indicate that the CF20 cohesive fatigue model can accurately reproduce the complex evolution of the delamination observed in the R-DCB.
