Cylindrical bending responses of angle-ply piezoelectric laminates with viscoelastic interfaces

Deflection of Cross-Ply Composite Laminates Induced by Piezoelectric Actuators

The coupling effects between the mechanical and electric properties of piezoelectric materials have drawn significant attention for their potential applications as sensors and actuators. In this investigation, two piezoelectric actuators are symmetrically surface bonded on a cross-ply composite laminate. Electric voltages with the same amplitude and opposite sign are applied to the two symmetri...

Improved Smeared and Zigzag Third-order Theories for Piezoelectric Angle-ply Laminated Cylindrical Shells under Electrothermomechanical Loads

On Bending Tests of Five - Ply

K-factor has Ions been used as a modifier of section modulus In the calculation of bending moment for plywood beams. No comparable modification of moment ot inertia is included In current reoommendatioDS for calculating plywood deflection at span-depth ratios of 30: 1 or greater. Results of limited testing lend support 'to the authors' contention that, where "shear" strains are signifIcant, the...

Cylindrical Bending of Laminated Plates with Distributed and Segmented Piezoelectric Actuators / Sensors

The generalized plane quasistatic deformations of linear piezoelectric laminated plates are analyzed by the Eshelby–Stroh formalism. The laminate consists of homogeneous elastic or piezoelectric laminae of arbitrary thickness and width. The three-dimensional differential equations of equilibrium for a piezoelectric body are exactly satisŽ ed at every point in the body. The analytical solution i...

A Bending-Gradient model for thick plates, Part II: Closed-form solutions for cylindrical bending of laminates

In the first part (Lebée and Sab, 2010a) of this two-part paper we have presented a new plate theory for out-of-plane loaded thick plates where the static unknowns are those of the Kirchhoff-Love theory (3 inplane stresses and 3 bending moments), to which six components are added representing the gradient of the bending moment. The new theory, called Bending-Gradient plate theory is an extensio...
