Laminated glass composed of several layers of glass plies bonded to a polymer interlayer enjoys ever growing interest in modern architecture. Being often used in impact protection designs requires understanding of both pre- and post-breakage behavior of these structures. This paper contributes to this subject by examining an application of an explicit phase field dynamic model to the description of fracture in a laminated glass subjected to a low velocity impact. The achieved results indicate the ability of the proposed model to successfully describe the onset of damage and subsequent crack propagation. It has, however, been observed that a relatively fine mesh is needed to interpolate a sharp discontinuity accurately, which makes this approach computationally demanding. The model is first validated against experimental results obtained for a single-layer float glass. Next, the usability of the phase-field damage model as a crack predictor in individual layers of the composite is investigated. The dependence of the results on residual stiffness, element type, and initial tensile strength is examined and discussed.

“…The program was compiled by using MATLAB software to calculate energy recovery, [27][28][29] so the energy recovered by unidirectional plates under different impact energy is shown in Table 6. The energy recovery is the largest when the impact energy is 300 J (Table 6).…”

Purpose: To study the response under impact load of carbon fiber reinforced composite materials that have excellent mechanical properties. Design/methodology/approach: Finite element analysis of unidirectional plates was conducted under unsymmetrical impact load based on drop weight impact test. At the macroscopic scale, a finite element model was built on ANSYS/LS-DYNA, which took the impact response of carbon fiber unidirectional plates as unknown quantity. The model considered the macroscopic response of carbon fiber unidirectional plates under different initial conditions, from the aspects of stress, strain, energy change and deformation degree of unidirectional plates. Finally, a mathematical model of energy recovery of carbon fiber composite materials under partial impact load was established, and the energy recovery amount under different fiber orientations was calculated on MATLAB. Findings: The impact energy absorbed by the unidirectional plate is the largest when the fiber orientation is 30°. To improve the impact resistance of unidirectional plates under unsymmetrical impact load, laying schemes should be avoided at fiber orientations of 0°, 15° and 60°, and be recommended at 30°, 45°, and 75°. For impact velocity, 4.71 and 7.54 m/s should be avoided, while 2 m/s is recommended. For the impact weight, 50 and 250 kg weights should be avoided, and 150 and 200 kg weights are recommended. Originality/value: This model not only provides reference for similar impact resistance research, but also predicts the impact response of unidirectional plates under different initial loads in the future. It can also provide reference for the structure using carbon fiber composite materials to achieve lightweight.

Considering the elastic–plastic deformation, the wave propagations and energy transmissions of the one-dimensional three-segment composite granular chain are studied. The axial symmetry model for elastic-perfectly plastic materials is built by using the finite element method. Six materials with different yield strengths are selected for the adjustable segment. The results show that the repeated loading and unloading behaviors, as well as the wave propagations in the elastic–plastic granular chain, are complex and significantly different from those in the purely elastic granular chain. The yield strength of the granular materials in the adjustable segment has significant effects on energy dissipation and wave velocity, which could be used to design the impact buffer. The studies show that taking lower yield strength for the adjustable part than the non-adjustable part, the energy dissipation could be increased, and the wave velocity could be reduced, then the arrival time of the impact waves could be delayed. These characteristics of the elastic–plastic granular chain could be used to design metamaterials for impact absorbers in impact protection.
