Abstract An enhancement of electromechanical performance in ferroelectric materials commonly requires a delicate control of compositions to the proximity of morphotropic phase boundary. Here, we demonstrate an alternative design strategy for enhanced electromechanical responses by engineering ferroelectric PbZr 1 − x Ti x O 3 nano-heterostructures, where the overall composition is near the morphotropic phase boundary yet compositions of constitutive layers are far from the boundary. Effects of l...

Abstract In this paper, we present polynomial varying modified polarization saturation models for semipermeable two unequal collinear cracks with coalesced interior zones in piezoelectric media. Under the influence of far-field electromechanical loadings, the cracks situated in an infinite arbitrary polarized piezoelectric media are opened in self-similar manner, forming a strip saturated zone in front of the cracks-tips. Here, we modify the polarization saturation (PS) model in a way by arresti...

Abstract This study presents an efficient beam formulation for static and vibration analysis of 2D non-prismatic beams with the kinematic assumptions of the Timoshenko beam theory. Beams having complex configurations can be straightforwardly constructed by using B-spline basis functions, which are used for descriptions of the beam axis and the sectional height. This feature enables analysis of free-form non-prismatic beams with strong curvatures to be performed conveniently and accurately, and i...

Abstract An effective computational approach that can simultaneously deal with several complexities in geometries, material properties, and size effects is of non-trivial yet important tasks for the design and optimization of device components in micro- and nano-electromechanical systems. This study is devoted to the development of such an effective computational approach, which is formed by integrating the modified couple stress theory into isogeometric analysis framework. The proposed approach...

Abstract This study presents a novel isogeometric Euler–Bernoulli beam formulation for geometrically nonlinear analysis of multi-patch beam structures. The proposed formulation is derived from the three-dimensional continuum theory where the beam axis and the director vectors of cross-sections are used to characterize beam configurations. The translational displacements of the beam axis and the axial cross-sectional rotation along the beam axis are considered as unknown kinematics. The orthogona...

Abstract In this paper, the isogeometric analysis (IGA) integrated with a simple first-order shear deformation theory (S-FSDT) with only four variables per node is extended to study geometrically nonlinear natural frequency, nonlinear static bending and transient dynamic response of two types of smart piezoelectric functionally graded plates (PFGPs) in thermal environment. The neutral surface is introduced to avoid the stretching-bending coupling effect. The nonlinear strain-displacement relatio...

Abstract The objective of this article is to simulate crack growth of complex Mindlin–Reissner plates by developing an adaptive multi-patch extended isogeometric analysis (XIGA). Nitsche’s method is used to treat continuity between multi-patches or the coupling of non-conforming meshes, exactly describing the geometry of complex plates. The computational meshes in XIGA are independent of the cracks by introducing some enrichment functions into the displacement approximation based on the partitio...

Abstract This paper presents a robust meshfree technique for computation of moment and stress intensity factors, and analysis of fatigue crack growth in cracked plates under the application of in- and out of-plane loads; a methodology for efficient and accurate computation of parameters of fracture mechanics problems is thus developed. Although having small computational labor and few complications of formulation, the proposed method has a high accuracy and convergence rate. By adding a few node...
