Numerical Simulation of Quasi-static Axial Compression of Carbon Fiber Composite Winding Aluminum Alloy Tube

With multilayer (10-layer) and few-layer (3-layer) carbon fiber composite winding aluminum alloy tube (Al-CFRP mixed tube) as the research object, the single-layer shell model, multi-layer conventional shell model and multi-layer continuous shell model were established with ABAQUS/Explicit finite element software. The axial compression deformation process of the hybrid tube was simulated with Hashin failure criterion. The simulation accuracy of each model was compared. The simulation relative errors of the initial peak load, specific energy absorption and average compression load and the simulation time were made dimensionless and weighted to evaluate each model comprehensively. The results show that the multi-layer shell model could better predict the damage deformation and energy absorption characteristics of the hybrid tubes under axial compression. For the multilayer winding hybrid tube, the best model was the multi-layer continuous shell model, while for the few-layer winding hybrid tube, the multilayer conventional shell model had the smallest error.
