✦ Synopsis
Based on a displacement ®eld which: (i) accounts for an arbitrary distribution of the tangential displacements through the shell thickness; (ii) ful®lls a priori the continuity conditions on the transverse shear stresses at the interfaces between the layers; (iii) ful®lls the zero transverse shear conditions on the top and bottom surfaces; and (iv) allows for jumps in the tangential displacements when interlayer slips are present, the equations governing the geometrically nonlinear elastodynamic behavior of multilayered composite shallow shells are derived by using the virtual work principle. First-order and third-order shallow shells models are obtained as special cases. The work is an extension of the multilayered composite shallow shells of a recently developed model for multilayered composite plates featuring damaged interfaces [AIAA J, 35(11) (1997) 1753].
