“…Even with a single element type, different mesh schemes at different regions lead to significant improvement in efficiency. Riccio et al [22,23] and Caputo et al [24,25] used solid elements throughout in a model to capture the lowvelocity impact damage of laminated composite; contact was used to tie the fine-mesh detailed local domain and coarse mesh global domain. This application was later developed for predicting impact damage in an all-composite wing-box structure [26], and numerical predictions coincided well with experimental data.…”

This paper investigates the effect of size and complexity of composite structures on the formation of low-velocity impact damage via experimental tests and numerical modelling. The ASTM standard low-velocity impact test and a scaled-up version of the test were conducted. A novel numerical technique is presented that combines 3D solid and thin 2D shell elements for modelling different domains to achieve a high level of fidelity locally under the impact location, whilst achieving good computational efficiency for large structures. Together with the experimental studies at the different scales, the predictive capability of the numerical models was systematically validated. This modelling method demonstrated an advanced computational efficiency without compromising predictive accuracy. The models are applied to a case study of low-velocity impact of a large-scale stringer-stiffened panel, showing this modelling approach to be suitable for predicating low-velocity impact damage and structural response of laminated composites over a range of sizes and complexities.

“…The damage evolution model including fracture energy of fiber and matrix has been introduced in many studies. 34,35 The strength and damage variables of each element nodes are closely related to their strains δ I . The relationships between the strain of element node and damage variables and composite strength are illustrated in Figure 1.…”

A modified progressive damage model is constructed to analyze the damage mechanics and damage development of composite laminates induced by low-velocity impact in this article. The damage modes are judged by the 3D Hashin failure criterion. A modified damage evolution model, which was constructed based on through-thickness normal strain component [Formula: see text], is implemented to describe progressive damage of composites. Cohesive elements with quadratic failure criterion and B-K criterion are applied to simulate the development of delamination. The 3D Hashin criterion and modified damage evolution model are coded in VUMAT and called in the ABAQUS/Explicit package. The damage distribution and mechanical behavior, including impactor energy, react force, displacement, predicted by numerical simulation are compared with the experimental data of different impact energies (7.35, 11.03, and 14.70 J). The numerical results and experimental data are in good agreement, which suggests that the modified damage evolution model is beneficial for studying the dynamic mechanical behavior during impact. Moreover, the influence of cohesive element thickness on numerical results is discussed. It is concluded that the cohesive element thickness should be adopted between 0.001 and 0.0075 mm.

“…However, applications have been limited to replicating experimental material coupon testing conditions and not expanded to more complex in-service structural environments. Alternatively, similar global-local models have also been developed by a number of authors [24,25,28] to reduce computational effort, where the higher fidelity 'local' model is used to predict laminate impact response and resulting impact damage fed into a lower fidelity 'global' model of the larger structure for prediction of postimpact loading and ultimate structural performance. One of the key limitations of this approach is the prediction of post-impact loading and damage progression is still highly sensitive to the idealisation and fidelity of the global model.…”
