Bending of Thick Rectangular Plates Laminated of Bimodulus Composite Materials
Additional Document Info
A mixed finite-element analysis is presented for static behavior of rectangular plates laminated of composite materials having finite transverse shear moduli and different elastic properties depending upon whether the fiber-direction strains are tensile or compressive. As a benchmark to assess the validity and accuracy of the finite-element analysis, a closed-form solution is given for a two-layer, cross-ply plate having all edges simply supported without in-plane restraint and subjected to sinusoidally distributed normal pressure. Numerical results obtained by the two methods are compared and found to agree quite well. 1981 American Institute of Aeronautics and Astronautics, Inc., All rights reserved.
