“…However, to simulate the deformation and fracture of composite parts and structures under the high-velocity impact, this approach in its pure form does not quite fit, since it does not allow taking into account material delamination. Several works may be noted [9][10][11][12][13][14][15], wherein the authors used a macro-scale approach in the simulation of impact loading of composite panels. The presented computational models allowed predicting the amount of absorbed energy with sufficient accuracy, but they did not provide a reasonable agreement between the computed and experimental fracture patterns.…”

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.

“…Three-dimensional (3D) braided composites are increasingly being used in the manufacturing of structural parts due to their incomparable advantages compared with traditional laminated composites in recent years. In order to ensure the safety and reliability in use of the 3D braided composite, the mesoscopic configuration modeling and mechanical performance prediction under multiple working conditions [ 1 , 2 , 3 , 4 , 5 , 6 ] of 3D braided composites have recently received considerable attention by many scholars. It is well known that the main body of the braided composites is matrix material, and polymer as matrix materials shows obvious viscoelasticity in composites.…”

A homogenization-based five-step multi-scale finite element (FsMsFE) simulation framework is developed to describe the time-temperature-dependent viscoelastic behavior of 3D braided four-directional composites. The current analysis was performed via three-scale finite element models, the fiber/matrix (microscopic) representative unit cell (RUC) model, the yarn/matrix (mesoscopic) representative unit cell model, and the macroscopic solid model with homogeneous property. Coupling the time-temperature equivalence principle, multi-phase finite element approach, Laplace transformation and Prony series fitting technology, the character of the stress relaxation behaviors at three scales subject to variation in temperature is investigated, and the equivalent time-dependent thermal expansion coefficients (TTEC), the equivalent time-dependent thermal relaxation modulus (TTRM) under micro-scale and meso-scale were predicted. Furthermore, the impacts of temperature, structural parameters and relaxation time on the time-dependent thermo-viscoelastic properties of 3D braided four-directional composites were studied.

“…However, traditional aeronautical materials such as aluminum alloys, titanium alloys and resin matrix laminated composites have been difficult to meet the growing performance requirements in aerospace industry. Therefore, constructing novel structural materials with better comprehensive performance and special properties is essential (Jiang et al., 2019; Shi et al., 2019; Zhang et al., 2017). Fiber metal laminates (FMLs) are a special type of hybrid composites that combine fiber composites and metals together, thus can benefit from the advantages of these two different materials.…”

Fiber metal laminates have been successfully applied in military aircrafts, armor vehicles and other modern engineering industries as protective structures due to their outstanding impact resistant properties. Prediction of the ballistic performance and investigation on the damage mechanism of the fiber metal laminates under general oblique impact conditions still remain a very challenging issue. In this study, a nonlinear dynamic finite element model in terms of continuum damage mechanics including intra- and inter-layer failure modes is presented. The accuracy of this model is validated with available experimental data. The damage and ballistic performance of two different structural fiber metal laminates subjected to high-velocity oblique impact by rigid hemispherical nose projectile with angles of 0°, 30°, 45° and 60° are studied. The numerical results show that the projectile deflects when the oblique impact occurs and the deflection angle decreases with increasing the impact velocity. The residual velocity of the projectile and the energy absorption of the target are related to the initial impact velocity and impact angle of the projectile. The proposed simulation approach offers a new proper reference for numerical investigations of common oblique impact problems in other fiber metal laminates.
