The presentation features a fully nonlinear analysis for prediction of
shear crippling (kinkband) instability propagating in a long thick
laminated composite cylindrical shell. The main result is prediction of
equilibrium paths. These paths are often unstable, appearing in the
presence of interlaminar shear deformation. A nonlinear 3D finite
element method is applied to study the failure modes under
radial/hydrostatic compressive loads. The 3D theory, possible
instability triggers and the computational features will be discussed.
