Nonlinear Viscoelastic Response of Unidirectional Polymeric Laminated Composite Plates Under Bending Loads

Abstract

Nonlinear bending analysis of polymeric laminated composite plate is examined considering material nonlinearity for viscoelastic matrix material through a Micro-macro approach. The micromechanical Simplified Unit Cell Method (SUCM) in three-dimensional closed-form solution is used for the overall behavior of the unidirectional composite in any combination of loading conditions. The elastic fibers are transversely isotropic where Schapery single integral equation in multiaxial stress state describes the matrix material by recursive-iterative formulation. The finite difference Dynamic Relaxation (DR) method is utilized to study the bending behavior of Mindlin annular sector plate including geometric nonlinearity under uniform lateral pressure with clamped and hinged edge constraints. The unsymmetrical laminated plate deflection is predicted for different thicknesses and also various pressures in different time steps and they are compared with elastic finite element results. As a main objective, the deflection results of viscoelastic laminated sector plate are obtained for various fiber volume fractions in the composite system.

Erosive wear behavior and dynamic mechanical analysis of textile material reinforced polymer composites

“…It varies with the state of the material, its temperature, and with the frequency . The damping behavior of composites in the transition region is governed by (1) mechanical relaxation of the matrix and loaded fiber (2) the interface between fiber and matrix (3) fiber loading and fiber length . Damping performance of composite materials can be controlled by the properties of the interfacial region which can be a two‐dimensional interface or a three dimensional interphase .…”
