【 摘 要 】

This paper presents a new discrete layer finite element to model thin as well as moderately thick orthotropic and laminated composite cylindrical shells. The element formulation is based on the first order shear deformation theory of shells. The twenty degrees of freedom plane stress element is modeled with inplane displacements defined at the interfaces of the element layers in addition to the, through the thickness, radial displacement. A field consistency approach is implemented to insure that the element is free from locking due to membrane tangential, membrane shear and transverse shear strains. The field consistency approach used eliminates the inconsistent terms from the original displacement shape functions that correspond to the targeted strains. The new element is validated through a series of benchmark problems and has shown accurate and fast converging results.
