“…• FE models verification % To ensure the accuracy of crack SIF calculations obtained from finite element (FE) models, a comparison can be made with analytical or numerical equations from literature. As part of numerical investigations, Hammond and Fawaz 23 conducted research on a cracked specimen with the same geometry and boundary conditions as shown in Figure 11, determining the correction factor (μ) value in equation (8). It should be noted that this study focused on materials with linear elastic properties.…”

Composite laminates have become increasingly popular in industries like aerospace and shipbuilding. In practical applications, the creation of notches in composite laminates is often necessary to enable assembly and modifications. This rise in the use of notched composite laminates highlights the need for reliable methods to predict potential failures in these components. With these predictions, the safety and reliability of composite structures can be ensured by preventing catastrophic failures. The present paper investigates the use of the Virtual Isotropic Material Concept (VIMC) combined with the Finite Fracture Mechanics (FFM) criterion to predict the Last Ply Failure (LPF) load in keyhole notched composite laminates and under mode I loading conditions. Experimental tests were conducted to measure the LPF load of E-glass/Epoxy keyhole notched specimens, and the results were compared with the predicted results using the VIMC-FFM criterion. The paper also derives an expression for the Stress Intensity Factor (SIF) function for a crack that emanates from the keyhole notch tip under mode I loading conditions. The derived equation matches very well with numerical data and have a mean absolute error about 2% in the studied domain. The study shows that the VIMC-FFM criterion predicts the LPF load of keyhole notched composite laminates with acceptable accuracy and in a simple and low-cost manner.

“…However, several works have been carried out to analyse the damage of composite structures utilizing progressive failure analysis (PFA) methodologies based on damage mechanics and failure criteria [1,2,3,4,5,6,7]. Matzenmiller's approach coupled with Hashin's failure criteria is being employed today as a specific tool of the PFA [8].…”

The purpose of this work aims to assess the failure of an open-hole composite laminate subjected to tensile loading, using different progressive damage approaches. Within Abaqus, a user-defined material subroutine (UMAT) was developed and implemented by applying a combination of Puck’s failure criterion and the gradual degradation model. In addition, the integrated model in Abaqus based on the Hashin failure criteria coupled with the continuous damage model has been also considered. Moreover, the effect of different specimen sizes on the behaviour of the AS4/PEEK composite laminate has been performed. The predicted results were compared to those available in the literature. The results of this comparative study showed good agreement between the experimental outcomes and the numerical predictions.

To develop continuous fibre compos laminates and fabrics in the aeronautics and aerospace industry, a thorough understanding of the behaviour of these materials under various loading conditions is required. The purpose of this work aims to assess the failure of different composite materials subjected to a bending load, using the progressive damage approach. Puck's failure criteria and gradual degradation model have been used to simulate the initial and the successive damage, respectively. A user-defined material (UMAT) subroutine has been developed and implemented through finite element software Abaqus. Moreover, the effect of geometrical parameters is performed and identified by the experimental protocol. The predicted results obtained by this numerical modelling show a good correlation with the findings of the experimental test.
