Accurate, efficient and versatile computational methods for functionally graded piezoelectric (FGP) shells are still restricted. This contribution proposes new FGP shell finite elements with superior comprehensive performance. In the formulation, a shell element is treated as a three-dimensional continuum and its middle surface is represented with...

This paper proposes a new shell element formulation using the scaled boundary finite element (SBFE) method. A shell element is treated as a three-dimensional continuum. Its bottom surface is approximated with a quadrilateral spectral element and the shell geometry is represented through normal scaling of the bottom surface. Neumann expansion is app...

This paper presents new shell elements for static and dynamic analyses of functionally graded plates and shells with the material properties varying through the thickness according to a power-law distribution in terms of the volume fractions of the constituents. In the formulation, a shell element is treated as a three-dimensional linear elastic bo...

This paper presents new variable-order shell elements that require only the shell mid-surface to be discretized, contain no rotational degree of freedom and adopt the full three-dimensional constitutive relationship. In the formulation, a shell element is treated as a three-dimensional continuum undergoing small deformations and its middle surface...

This paper develops an efficient modeling technique based on the scaled boundary finite element method (SBFEM) for transient vibro-acoustic analysis of plates and shells. For simulating the structural dynamic behaviors, a novel shell formulation based on three-dimensional linear elastic theory is presented where only the bottom surface of the shell...

A modeling technique based on the scaled boundary finite element method is developed for both static and dynamic analyses of cylindrical shells. A new scaling strategy is employed to ensure that the shell boundaries and the cross sections at the element inferfaces are accurately represented through the scaling process. The formulation starts direct...

This paper develops a unified and efficient simulation technique based on the scaled boundary finite element method (SBFEM) for transient structural–acoustic problems in two dimensions. The structural component can be an assembly of thin to moderately thick unidirectional plates. Each of them is treated as a plane strain problem and the principle o...

A unified technique based on the scaled boundary finite element method is presented in this paper to analyze the bending, free vibration and forced vibration of thin to moderately thick beams with constant material properties and rectangular cross sections. The structure model is treated as a plane stress problem and the principle of virtual work i...
