ABSTRACT


This paper extends the applicability of a new stress analysis method to the accurate determination of the detailed stress distributions in laminated plates in clamp region. The theoretical model presented here incorporates laminate deformations which account for the effects of transverse shear deformation, transverse normal strain-stress and a nonlinear variation of in-plane displacements with respect to the thickness coordinate. Thus, this model includes the warping of transverse cross-sections more accurately and eliminates the need of shear correction coefficients. Two numerical examples are discussed: the bending of elastically clamped beam and dynamic bending of centrally supported beam.

Key words: composite beams, clamped plates, elastic constants, identification.
