Abstract The paper presents an effective thin plate formulation based on isogeometric analysis (IGA) and a non-classical Kirchhoff plate theory to study static bending, free vibration, and buckling behaviors of homogeneous and functionally graded microplates. The small scale effects are captured using a non-classical Kirchhoff plate theory which is developed based on a modified couple stress theory. The requirement for C 1 -continuity in terms of the non-classical Kirchhoff plate theory is strai...

Abstract The paper presents an effective plate formulation based on isogeometric analysis (IGA) and a novel simple quasi-3D hyperbolic shear deformation theory (S-Q3HSDT) to study static bending, free vibration, and buckling behaviors of functionally graded plates. In S-Q3HSDT fashion, five unknowns per node are included; both shear deformation and thickness-stretching effects across the thickness are taken into account; and the awkward shear locking phenomenon is avoided. The requirement for C1...

Abstract Functionally graded materials often operate in high temperature environment, and have been extensively used in a variety of engineering applications including nuclear power plant and spacecraft. In this paper, we present new numerical results of mechanical behavior for functionally graded sandwich plates in high temperature. We investigate material combinations and stress distribution of sandwich plates with FGM faces. One interesting physical point is captured. It shows that not all sa...

Abstract Numerical estimation of stress intensity factors (SIFs), an important fracture mechanics parameter, for sharp V-notched structures is presented by using a new effective approach based on strain energy method associated with extended finite element method (XFEM). This approach takes advantages of both enrichments and the strain energy method. While enrichments allow the representation of notch-faces independent of the mesh, the strain energy approach is however used for the evaluation of...

Numerical analysis of 3-D elasto-plastic large deformations is presented.Isogeometric analysis based on Bzier extraction of NURBS is extended to 3-D elasto-plastic large deformation.The Bzier extraction operator can integrate isogeometric analysis into the existing finite element codes.Higher accuracy is obtained as compared with that of finite element method. This paper is devoted to the numerical simulation of elasto-plastic large deformation in three-dimensional (3-D) solids using isogeometri...

Abstract Practical applications such as airplane wings are usually subjected to combined thermal and mechanical loads, and they hence are prone to buckling failure. Preceding works on the buckling of advanced materials, e.g., functionally graded materials, under combined thermal and mechanical loads are rather rare in literature. In this paper, we report new numerical results of thermal-mechanical buckling of functionally graded rectangular and skew plates (FGPs) under combined thermal and mecha...

The paper is concerned with eigen buckling analysis of curvilinear shells with and without cutouts by an effective meshfree method. In particular, shallow shell, cylinder and perforated cylinder buckling problems are considered. A Galerkin meshfree reproducing kernel (RK) approach is then developed. The present meshfree curvilinear shell model is based on Reissner-Mindlin plate formulation, which allows the transverse shear deformation of the curved shells. There are five degrees of freedom per ...

Abstract A novel local mesh refinement approach for fracture analysis of three-dimensional (3-D) linear elastic solids is developed, considering both 3-D straight and curved planar cracks. The present local mesh refinement formulation is a combination of the extended finite element method (XFEM), variable-node hexahedron elements, and a posteriori error indicator. Our 3-D formulation using hexahedron elements rigorously embraces a posteriori error estimation scheme, a structural coupling scale-m...

Abstract Numerical investigation of buckling and free vibration of functionally graded plates considering in-plane material inhomogeneity is presented in this paper. A novel and effective approach based on isogeometric analysis (IGA) and higher-order shear deformation theory (HSDT) is developed for fulfilling that purpose, analyzing the critical buckling parameter and natural eigenvalues of functionally graded plates involving the in-plane material inhomogeneity. The HSDT allows us to account fo...
