“…Nowadays, software packages that use finite element method (FEM), such as ANSYS, LS-DYNA, ABAQUS, Simcenter 3D are widely used for mechanical behaviour analysis of FRP parts under different loading conditions. A series of articles [4][5][6] on the development of methods of stress-strain state and strength analysis of CFRP outlet straightener blade for new turbofan engine PD-14 under quasi-static loading is one of the first examples of using numerical methods for designing of load-bearing composite elements in Russian aircraft engine building. A significant amount of work related to the increasing the amount of composite materials in the perspective turbofan engines PD-14 and PD-35 is performed today, and the most important task for engineers is to create a composite fan blade and a fan case for them.…”

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.
