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 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 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 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 A numerical technique, based upon a scaled boundary finite-element (SBFE) method, is proposed for the analysis of a two-dimensional, infinite, elastic, layered medium under arbitrary surface loads and surface energy effects. The governing equations of the bulk layers and the material surface/interfaces were formulated from linear elasticity and Gurtin-Murdoch surface elasticity theories, respectively. The SBFE formulation was established in a general context to handle both homogenous an...

Abstract The consecutive-interpolation procedure (CIP) has been recently proposed as an enhanced technique for traditional finite element method (FEM) with various desirable properties such as continuous nodal gradients and higher accuracy without increasing the total number of degrees of freedom (DOFs). It is common knowledge that linear finite elements, e.g., four-node quadrilateral (Q4) or eight-node hexahedral (HH8) elements, are not highly suitable for geometrically nonlinear analysis. The ...

Abstract Innovations of advanced materials have been at the core of most engineering technologies, devices and systems. Composite laminates in particular have been extensively employed in many major and advanced industries including aircraft, maritime transport, and automobiles. Failure in composite structures is critical and often complicated, and that is the consequence of the evolution of and interactions among the constitutive fracture events (e.g., matrix cracking, fibre/matrix debonding, d...

This paper is devoted to numerical investigations on mechanical behavior of cracked composite functionally graded (FG) plates. We thus develop an efficient adaptive approach in terms of the extended isogeometric analysis (XIGA) enhanced by locally refined non-uniform rational B-spline (LR NURBS) for natural frequency and buckling analysis of cracked FG Mindlin–Reissner plates. In this setting, the crack geometries, which are described by the level sets, are independent of the computational mesh;...
