A zigzag model for laminated composite beams
In the present work, a zigzag model for symmetric laminated beam is developed. This model uses a sine term to represent the nonlinear displacement field across the thickness as compared to a third order polynomial term in conventional theories. Transverse shear stress and strain are represented by a cosine term as compared to parabolic term. This model satisfies displacement and transverse shea...
متن کاملMethod of Initial Functions for Composite Laminated Beams
In this paper method of initial functions is used for the study of composite laminated beams. The distribution of bending and shear stresses in composite laminated beams are different from beams of small thickness. The equations of two dimensional elasticity have been used for deriving governing equations. The order of the derived equations depends on the stage at which the series representing ...

متن کاملOn the Linear Viscoelasticity of Thin-Walled Laminated Composite Beams
An analytical model to predict the linear viscoelastic behavior of thin-walled laminated fiber-reinforced plastic (FRP) composite beams is presented. Using the correspondence principle, this new model integrates micro/macro-mechanics of composites and mechanics of thin-walled laminated beams to perform beam. analyses in the Laplace or Carson domains. The analytical expressions for beam relaxati...
متن کاملExperimental Investigation of the Dynamic Characteristics of Laminated Composite Beams
The laminated composite beams are basic structural components used in a variety of engineering structures such as airplane wings, helicopter blades and turbine blades as well as many others in the aerospace, mechanical, and civil industries. An important element in the dynamic analysis of composite beams is the computation of their natural frequencies and mode shapes. This is important because ...
