| Abstract: | The paper outlines the results of an investigation to characterize the response of P75/934 graphite/epoxy tubes with a stacking
sequence of 15/0/±10/0/−15]
s
under pure torsion and combined axial/torsion loading. The experimentally observed nonlinear response and path-dependent
failure are discussed in terms of material nonlinearities at the ply level and first-ply failure loads with the help of an
analytical model.
