CAI, D. ...et al., Failure analysis of a frangible composite cover: A transient-dynamics study. Journal of Composite Materials, In Press.
A transient-dynamics model based on the approximate Riemann algorithm is proposed for the failure analysis of a
frangible composite canister cover. The frangible cover, manufactured with a traditional manual lay-up method, is
designed to conduct a simulated missile launch test using a specially developed test device. Deformation of the
cover’s centre is determined using a transient-dynamics finite element model; failure pressure for the frangible cover
is obtained based on a failure criterion and compared with simulated experimental results. Weak-zone position of the
frangible cover has a significant effect on failure pressure compared to that of deformation of the cover’s centre. With
the same structure of the weak-zone, an increase in its height can first raise and then reduce the level of failure pressure
of the frangible cover. Close agreements between the experimental and numerical results are observed.
