Assessment of Multilayered Plates with Hyperelastic Coatings Subjected to Dynamic Loadings by Impact at Low Velocities


Abstract:
This paper describes the use of video and digital image processing in investigation of the impact between a rigid hemispherical shape impactor and Hybrid Polyurea-Polyurethane-MWCNTs Nanocomposite Coatings. An experimental study was performed for six sample configurations: single aluminum plates (reference test), multilayer plates with 4 types of coatings and double aluminum plates. The impact phenomenon was recorded with a high-speed video camera and the variation of the projectile's velocity during the impact was obtained through digital analysis. Additionally, the test was instrumented using a force sensor specially designed and mounted on the impactor. The video processing was used to draw the velocity curves and to estimate the evolution of the contact forces between the impactor and the multilayer structures, the results obtained being compared with the force sensor data. Some differences between these two types of measurements are observed, so in order to analyze the configurations behavior, a numerical study of the phenomena was performed in LS-DYNA software using a 2D axial symmetric model. The simulations showed that the profile of the force evolution measured with the sensor is affected by the chosen constructive solution and the data obtained based on the video images are more accurate. The deformations were analyzed, the maximum deformation based on image processing and the residual deformation based on 3D Scan post-test. The video technique combined with 3D Scan are precise enough to study the impact at low velocities and the numerical simulations provide results according to reality. The hyperelastic coatings contribute to a better resistance of the aluminum plates.
