HIGH ORDER THEORIES FOR INVESTIGATION OF LAMINATED STRUCTURES WITH CLAMP CONDITION
Journal Title: ELECTRONIC JOURNAL OF POLISH AGRICULTURAL UNIVERSITIES - Year 2009, Vol 12, Issue 2
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, transver se normal strain-stress and a nonlinear variation of in-plane displacements with respect to the thickness coordinate. Thus, this model includes the wa rping 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.
