“…The accuracy of the numerical model is verified by the experimental results. Although many papers in the existing literature already addressed this subject with very similar experimental or numerical approaches, 44,45 there are relatively few systematic studies on the influence of the mechanical properties and structural characteristics of the interface on layered materials. In addition, the numerical calculation in this paper not only makes use of the computational advantages of CDEM in crack problems but also introduces the theoretical calculation formula of spring stiffness into the CDEM calculation framework for the first time, which solves the disadvantages of the empirical value of spring stiffness in traditional CDEM and FDEM.…”

Crack behavior at the interface between two materials is the core problem of layered material fracturing. In this paper, first, experimental tests were conducted on layered material using a drop weight test system following the caustics method. The layered material was made of poly (methyl methacrylate) (PMMA) and epoxy resin bonded with Loctite-330 at two inclination angles (30 and 60 ). A corresponding numerical simulation was carried out using continuum-discontinuum element methods. Crack propagation is found to mainly occur in mode I in the PMMA and epoxy resin but follows a mixed cracking mode at the interface. The fracture parameters of the crack tip in the layered materials changed substantially owing to the existence and change of the interface structure. After the crack enters the interface, the crack propagation speed increases significantly. Higher crack dip angles are associated with greater crack propagation speed increases after entering the interface. The simulation results indicate that the interface strength properties affect crack behavior at the interface. This effect also varies as a function of interface inclination and impact velocity.

“…Starting from the matching test of the coating and changing the coating process, Zhang studied how to improve the stone impact resistance performance of the coating on a hot-dip galvanized steel plate by conducting the stone impact resistance test of different medium coating materials and adopting the new process of adding a layer of anti-stone-hit coating [13]. Xu et al conducted an experimental investigation for dynamic crack-interface interactions in SGP laminated glass [14].…”

Damage to the body or critical components caused by stone strikes to automotive coatings affects the safety of the car. More and more attention are being paid to the study of the anti-stone-damage mechanism of coatings. Firstly, a computational fluid dynamics (CFD) model was established based on a single-impact anti-stone tester, and the simulation results show the following: (a) At 90° incidence, the air pressure of the stone impact suddenly and rapidly increases when the semicircular surface projectile velocity is greater than 30 m/s. The air pressure of the conical projectile stone at the distance of 0.3 and 0.15 mm suddenly increases at the projectile velocity of 10 and 20 m/s, respectively. (b) When the projectile velocity exceeds 15 m/s, the pressure of the semicircular surface projectile suddenly increases. (c) When the speed is less than 20 m/s, the shedding area decreases with the increase in the speed, while the stone impact pressure increases with the increase in the speed. Then, the simulation results of the incident velocity of 40 m/s show that the working pressure is 195.48 kPa, and the impact force is 8142.56 N. Finally, the relationship between the impact force and the driving air flow pressure was obtained according to the DIN 55996-1 standard stone impact resistance test and compared with the simulation results, showing that trend of the impact force increasing with the increase in driving air flow pressure is consistent, the simulation results are about 1.40 times the experimental results, and the simulation results are large and can be considered by increasing the test correction coefficient adjustment. Based on the CFD method, research on the mechanism of anti-stone-damage automotive coating can greatly reduce the number of stone strike instrument experiments, shorten the cycle, and reduce the research and development costs.
