Stress-based Formulation Non-linear Bending Analysis of Anisotropic Sector Plates

In this paper non-linear bending analysis of anisotropic sector plate is extended by developing stress-based formulation. The governing equations include a system of thirteen partial differential equations that involve five constitutive equilibrium equations and eight equations in terms of stress resultants. Forces and moments are calculated using shear and normal stresses that parabolic distribution is assumed for shear stress relations. Finally the resulted equation comprised with strain-displacement based formulation. © 2011 Published by Elsevier Ltd. Selection and peer-review under responsibility of ICM11
