Abstract
A predictive method for estimation of stress state at zone of crack tip and assessment of remaining component lifetime depend on the stress intensity factor (SIF). This paper discusses the numerical approach for prediction of first ply failure load (FL), progressive failure load, SIF and critical SIF for multiple cracks configurations of laminated composite finite plate using finite element method (FEM). The Hashin and Chang failure criterion are incorporated in ABAQUS using subroutine approach user defined field variables (USDFLD) for prediction of progressive fracture response of laminated composite finite plate, which is not directly available in the software. A tensile experiment on laminated composite finite plate with stress concentration is performed to validate the numerically predicted subroutine results, shows excellent agreement. The typical results are presented to examine effect of changing the crack tip distance (S), crack offset distance (H), and stacking fiber angle (θ) on FL, and SIF .

A predictive method for the estimation of stress state at the zone of a crack tip and the assessment of remaining component life depend on the stress intensity factor. As a part of a linear elastic fracture mechanics analysis the determination of the stress intensity factor is a crucial point. This paper presents the finite element approach for the prediction of the stress intensity factor for multiple offset edge crack configurations. The predicted stress intensity factors are validated with an...

Abstract Fracture toughness of single edge notched fiber reinforced composite plates is investigated experimentally. Load–displacement curves for unidirectional carbon fiber/epoxy resin reinforced composite plates are obtained experimentally under tensile load. Fracture toughness is obtained by determining failure loads. For numerical study, ANSYS is used. Material properties of laminates are calculated with classical laminated plate theory and applied to the finite element model by using plane ...

This paper proposes a micromechanics-based progressive failure analysis strategy for fibre-reinforced composites. A non-iterative element-failure method (NEFM) is developed and integrated with a micromechanics-based failure criterion. The micromechanics of failure (MMF) is further investigated and modified to improve predictions. The NEFM is focused on implementation of damaged elements with direct solution and implicit nodal forces. Progressive failure of fibre-reinforced laminates is analysed ...

Abstract The two-dimensional and three-dimensional parametric finite element analysis (FEA) of composite flat laminates with two through-the-width delamination types: 0 4 /(± θ ) 6 //0 4 and 0 4 //(± θ ) 6 //0 4 ( θ = 0°, 45°, and “//” denotes the delaminated interface) under compressive load are performed to explore the effects of multiple delaminations on the postbuckling properties. The virtual crack closure technique which is employed to calculate the energy release rate (ERR) for crack prop...

A representative volume cell (RVC) is chosen to analyze the progressive damage behavior of 3D four-directional braided composites with large braid angle subjected to uniaxial tension. An anisotropic damage model is established by Murakami-Ohno damage theory. A new damage evolvement model is proposed, which is controlled by material fracture energy of braided composites constituents and equivalence displacements. According to the different damage modes (yarn transverse tension, compression and sh...

Abstract The asymptotic solution of the singular stress field near a singular point is generally comprised of one or more singular terms in the form of Kr λ - 1 f ij ( θ ) . Based on the asymptotic solution of the singular stress field and the common numerical solution (stresses or displacements) obtained by an ordinary tool such as the finite element method or boundary element method, a simple and effective numerical method is developed to calculate stress intensity factors for one and two sing...

Abstract Based on the CDM theory, an energy-based stiffness degradation method is proposed to predict the progressive failure properties of the Al–carbon fiber/epoxy composite laminates. For carbon fiber/epoxy composites, three failure modes: fiber breakage, matrix cracking and fiber/matrix interface failure are included in the present model. A 3D finite element technique including the multiframe restart analysis and the arc-length algorithm is developed to perform the progressive failure analys...

Modeling progressive damage in composite materials and structures poses considerable challenges because damage is, in general, complex and involves multiple modes such as delamination, transverse cracking, fiber breakage, fiber pullout, etc. Clearly, damage in composites can be investigated at different length scales, ranging from the micromechanical to the macromechanical specimen and structural scales. In this article, a simple but novel finite-element-based method for modeling progressive dam...

This paper introduces an interface element to solve 2D progressive crack growth problems under mixed-mode loading. The interface element is developed to calculate the strain energy release rates based on the virtual crack closure technique (VCCT) in conjunction with finite element analysis (FEA). A very stiff spring is placed between the node pair at the crack tip to calculate the internal forces. Dummy nodes are introduced to extract information for displacement openings behind the crack tip an...

The multiaxiality factor defined as the ratio of the von-Misses equivalent stress to the volumetric stress has been reported to be related to the initiation and progression of failure in structures. It is demonstrated in the present paper that the location around the crack tip where the multiaxiality factor obtains minimum value is an indicator of the direction of minimum material fracture resistance for crack propagation. It is also proposed that the location along the direction of crack propag...
