“…Also, the XFEM-VCCT approach is mesh-sensitive because it depends on nodal forces and displacements. Swati et al [40] used the XFEM technique with cohesive elements to understand the crack propagation behavior in CFRP composites and found it the most suitable crack propagation simulation technique for complex threedimensional problems. Benzaama et al [41] used the XFEM technique for crack propagation modeling in unidirectional CFRP composites and found it very suitable for predicting crack propagation.…”

The interlaminar fracture is the most common type of failure in polymeric textile composites because these composites are prone to delaminate under the influence of external loading. Depending on the type of deformation, the interlayer fracture can be Mode-I, Mode-II, Mode-III, and Mixed Mode-I/II type. In this research work, Mode-I interlaminar fracture modeling of carbon fiber reinforced polymer (CFRP) composite laminate is performed using a double cantilever beam (DCB) test specimen on ABAQUS software as a cost-effective numerical simulation approach. The finite element based fracture modeling techniques, virtual crack closure technique (VCCT), cohesive zone modeling (CZM), and extended finite element method (XFEM) were employed under the two-dimensional and three-dimensional interlayer crack propagation to evaluate the load-displacement responses. The interaction properties were applied between the top and bottom part of DCB specimen and the adhesive layer was modeled using the CZM approach. The numerically simulated responses were compared with the published experimental load-displacement responses and found to be in good agreement. All the fracture modeling approaches validate the experimental trend, however the three-dimensional XFEM technique was found to be the most suitable modeling approach for crack growth in adhesively bonded parts. The stress based criteria was used for crack initiation, whereas the energy based approach used for crack propagation in DCB laminate. The parametric study of various fracture parameters (cohesive strength, fracture energy, interfacial stiffness, laminate thickness, and pre-crack length) were also conducted to understand their effects on load-displacement responses of the Mode-I interlaminar fracture. The fracture modeling approaches were compared by considering the element type, shape, total elements, accuracy, run-time, increments, and convergence speed.

“…The demonstration of crack propagation with the ABAQUS XFEM results of the composite carbon fiber trends was a previous trend to verify the experimental results of several studies. [17] - [19] ABAQUS uses the national definitions of physical models and interactions of carbon fiber composite samples with the multiple trends and designs described in Table 3. The numerical model presented in the previous section is validated and compared to the results based on the maximum stress criterion.…”

“…Carbon fiber reinforced polymers (CFRP) have been commonly used in the aerospace, shipbuilding and automotive industries for decades. With the extensive application of CFRP, the investigation of mechanisms for damage to CFRP structures was a major concern for the further development of CFRP in engineering structures [5] - [8]. At present, there are no reliable digital approaches that provide engineers and researchers with effective predictability of damage and failure when designing composite fiber structures.…”

Mughal, M. (2019). Investigation of tensile and inplane shear properties of carbon fiber reinforced composites with and without piezoelectric patches for microcrack propagation using extended finite element method. AbstractThe smart materials are capable to integrate the remarkabale active functions into a traditional structure of the composites. There is a wide reaseach possibility towards the embedded patches into a composite primary structure. This particular study aims to investigate the effect of the embedded smart materials in a conventional composite laminate. Carbon Fiber Reinforced Composite specimens with and without PZT piezo elements embedded in the structure are studied for Tensile, In-plane Shear and three point bending properties. Previously researched mechanical behaviour and the operational influence of the piezo sensors are sequentially analysed, particularly for the elecetric capacitance during all the categories of testing. The limitations have also been studied into the comparison of the structure with and without the piezoelectric material patches. The extended Finite Element (XFEM) modelling approach has been applied to study the sensorized damage model for the numerical and experimental study. This study also presents simplified and understandable techniques and offers a new direction for the experimental and computational modelling design for the progressive damage, based on the principles of Extended Finite Element Method (XFEM). The extensive experimentation and numerical modelling for interlaminar and intralaminar crack of Carbon Fiber Reinforced Composite CFRCs materials are studied, with and without piezoelectric patches. The experiments and simulations are designed and grouped into categories of load, boundary conditions and types arranged accordingly for fracture, delamination, fiber breakage and matrix crack towards the damage evolution. The dimensions of the specimens and the effects are also studied regarding lengths, thickness and width in multiple categories. The loading cases of tension and the inplane shear are studied for multiple cases for numerical as well as experimental investigation having different orientations and dimensions. The delaminated and fractured mode I and mode II specimen were analysed for the expected and the real time values of strength to figure out the precise values of trends to predict the composite properties.

This paper introduces an investigation on fracture mechanisms of synthetic foam sandwiches with graded multi-layered cores. The extended cohesive damage model (ECDM) is used in investigating detailed fracture mechanisms of this kind of synthetic foam sandwich panels under quasi-static 3-point bending. The ECDM prediction shows very good agreements with experimental work on investigating the sandwiches with homogeneous core and the core with four graded layers. This investigation has found that the failure modes of sandwich panels with multi-layered cores are sliding shear failure dominated fracture in the core along the path above the core-bottom sheet interface instead of pure debonding at interfaces. It has been also found an excellent mechanical performance when the core has multiple graded layers in the investigated sandwiches compared to the case of homogenous core. It is the first time that the correlation between loading capacity and number of graded layers in the core of the investigated synthetic foam sandwiches is explored. The ECDM predicted loading capacity of the investigated sandwich panel with an 8-layered core is increased by 70% compared to a homogenous core. This investigation also shows that the ECDM is a robust tool for predicting fracture mechanisms of synthetic foam sandwiches.
