Nonlinear deformation of carbon fiber reinforced plastics: experiment, model, and simulation
The current study focuses on modeling of the nonlinear behavior for carbon fiber reinforced plastics (CFRP), which are one of the most promising classes of advanced composite materials. A complete procedure of developing mathematical models for a nonlinear elastic flexural deformation of polymeric matrixes and CFRPs has been proposed and implemented. It takes into account the SD effect, i.e. the difference between the tensile and compression strengths. The mathematical tools for the analysis and processing of big data sets containing the results of mechanical tests were offered. They also can be used to eliminate the most significant artifacts of these tests. The tools considered here are based on both qualitative and regression analysis using the method of least-squares and the methods without saturation. Mathematical relations describing nonlinear elastic three-point bending of isotropic and reinforced beams with the SD effect were derived. An algorithm for numerical solution of the corresponding boundary value problem was proposed. A comparison of the results of computer simulations with experimental data obtained using mechanical testing has been done. The developed approach and the constructed mathematical models have shown that they are efficient for the computer simulation of a three-point bending of CFRP and polymeric beams. Simulation results are in good agreement with the results of mechanical testing. It has been established and it is shown that it is necessary to take into account the nonlinear properties and especially the SD effect of polymeric matrixes and CFRPs when simulating and designing the structures made from CFRP.
