Abstract In this study, recycled polyethylene terephthalate (PET) bottles are shredded in different sizes and added to the polymer concrete composition to investigate the effect on the fracture toughness and fracture energy as well as an idea to reduce the environmental pollution. In order to measure the mode I fracture toughness, center cracked Brazilian disk (CBD) specimens are manufactured with 20 wt% epoxy resin and 80 wt% quartz aggregate in the size of 2.4–4.75 mm. Recycled PET fillers in ...

Abstract In this study, virtual crack closure technique (VCCT) and extended finite element method (XFEM) are coupled to each other as XFEM-VCCT approach to simulate mode I fatigue delamination growth in composites, employing the direct cyclic method in Abaqus. Both two-dimensional plane strain and three-dimensional finite element models under force and displacement control are considered. Numerical simulation results are compared with the existed experimental test data for double cantilever beam...

Abstract In this study, the Turon et al. and Kawashita-Hallett fatigue damage models are extended with a trilinear cohesive law to simulate mode I fatigue delamination in the composites undergoing large-scale fiber bridging. The trilinear cohesive zone model (CZM) is constructed by superposition of two bilinear CZMs. In order to implement the developed models, a user defined element (UEL) subroutine is prepared in the Abaqus software and finite element analyses are conducted based on the envelop...

Abstract The combination of two joining mechanisms – bonding and bolting – in a single hybrid joint may potentially result in a stronger and more durable joint than either of the separate constituents. Studies have shown that the load sharing between the adhesive and the bolt is a key parameter for such an improvement. The present work executes a parametric study on single-lap hybrid bonded/bolted composite joints with multiple bolts. Joints of five different geometric configurations are subject...

Abstract A combination of bonding and bolting can potentially improve the joining efficiency of composite structures. Several researchers have shown that in specific cases, the joint yield and ultimate strength can be improved in this manner compared to the underlying joints separately. However, their results also demonstrate a strong sensitivity to various design parameters. In this study, the effect of adhesive layer compliance is experimentally investigated on the single-lap hybrid bonded-bol...

In this study, a new closed-form solution for transverse free vibration analysis of laminated composite beams (LCBs) with arbitrary number of concentrated masses is developed. The LCB is modeled based on the Euler–Bernoulli beam theory and concentrated masses are simulated considering Dirac delta function. Obtained governing equations are, then, solved semianalytically, while the frequency equation and mode shapes are extracted for two different boundary conditions, i.e., clamped-free and simply...

Abstract Additive manufacturing of fiber reinforced composites is of great interest in various industrial applications. In this study, an innovative extruder is designed and manufactured for fused deposition modeling (FDM) 3D printers in order to produce continuous fiber reinforced thermoplastic (CFRT) composites. There are some challenges along this way such as making tension in fiber, fiber surface preparation, printing temperature and feed rate to produce a composite part with good quality. T...
