摘要: Abstract A novel analytical model has been developed to predict the mean crushing force of square carbon fibre reinforced plastic (CFRP) tubes subjected axial crushing. The captured experimentally observed major energy dissipating mechanisms CFRP under compression, i.e. crack propagation, transverse shearing and friction. Transverse taken into account for first time in this model. Quasi-static compressive tests have conducted on 16 with various side lengths wall thicknesses determine their forces. discrepancy between analytically predicted measured forces these is no more than 7%. Moreover, proposed very simple only several parameters, which can be determined via relatively experimental tests.
