“…Starting point is the cohesive law by Turon et al [42]. Rate-dependency is introduced for the cohesive strength and fracture energy following May [21,22]. By setting the rate sensitivity parameters in the rate-dependent cohesive law to be zero, the cohesive law introduced by Turon et al [42] is recovered.…”

“…Rate dependency is introduced for both the cohesive strength and the fracture energy of independent modes with a Johnson-Cook law similar to May [21,22]. For pure mode-I or mode-II, the following relation is introduced,…”

“…The first category of models assumes that some characteristic parameters (e.g. the fracture energy) of a chosen cohesive law are functions of the separation rate of the cohesive surface [18][19][20][21][22][23][24]. The second category modifies the classical damage evolution formulation into a rate form, thus limiting the damage rate to a certain maximum [7,25,26].…”

The mode-I interlaminar fracture toughness of composite laminates under different loading rates can be measured by the double cantilever beam (DCB) test. It is observed from the DCB test of a unidirectional PEEK/carbon composite laminate that as the loading rate increases from quasi-static to dynamic range: (1) delamination crack growth exhibits a transition from stable to unstable ("stick/slip") and back to a stable type; (2) the interlaminar fracture toughness is not constant as the loading rate increases. In this paper, two numerical approaches are used to reproduce the experimental observations: a cohesive zone model (CZM) and the interfacial thick level set (ITLS) model. CZM simulations with rate-independent and rate-dependent cohesive laws are carried out. A new version of the ITLS is introduced with a phenomenological relation between crack speed and energy release rate. The simulation results of the CZM and the ITLS model are compared with the real DCB test data to evaluate the capability of these two types of models. It is found that the used CZM can reproduce rate-dependence of the fracture energy, but not the stick/slip behavior. The ITLS can capture the stick/slip behavior, but needs different parameter sets for different loading rates.

“…Hundreds of papers have been published, wherein the authors used cohesive elements in ply-level simulations of FRP impact loading [16][17][18][19][20][21][22][23][24]. This approach is quite effective and allows using both shell and solid elements in calculations.…”

Currently, modern CAE programs like ANSYS, LS-DYNA, ABAQUS, Simcenter 3D etc. are widely used to develop each engineering product. CAE reduces development costs and speeds up product launches. Computer modelling allows eliminating unsuccessful design options at early design stages and minimising or eliminating critical design changes at the prototype testing stage. Computer simulations are especially needed for the development of high-performance perfection designs like jet engines. The use of composites in the engines requires the availability of appropriate design tools to assess the mechanical behaviour of structural elements made of such materials under operational loads and in an emergency. Predictive modelling of the deformation and fracture of the composite fan blades and fan case subjected to dynamic loading cause considerable interest of engineers. As in the case of simulation of shock loading of metals, a model of a composite material must be verified. However, the problem is that the fibrous composite material itself is already a structure and can be modelled in various ways: without considering the layered structure (homogeneous approach) taking the mesostructure into account (at the ply-level or at the yarn-level) taking the microstructure into account (at the filament level). The requirements for the initial data, the number of parameters determined during the verification process, the complexity of creating geometric models will differ in each case. This paper briefly describes the main approaches to the numerical simulation of composite elements under highvelocity impact loading. The main advantages and disadvantages of these approaches are also considered. On the example of the meso-scale approach, the main parameters of the computational models that affect the results of calculations are shown. Based on the obtained data, the main recommendations were formulated on the validation of meso-scale models of composites.

“…It has been utilised by Santiuste et al [3] to study the out-of-plane failure of composites during orthogonal cutting of LFRP composites, and also implemented to simulate delamination both for more complex machining operations such as drilling [14,15] than for impact problems on composites [16,17]. Recently, several studies have focused on the development of more accurate and realistic cohesive models by introducing a dependence on strain rate [18] and an elasto-plastic phase in the constitutive law [19], or implementing new approaches for the interface simulation such as the smoothed particle hydrodynamics (SPH) method [20]. The cohesive zone model has been also used in the micromechanical approach for modelling the matrix-bre link, which is crucial for simulating debonding of the phases.…”
