Semi-analytical analysis for piezoelectric plate using the scaled boundary finite-element method
Computers & Structures, 2014Abstract This paper presents an accurate semi-analytical technique to analyse piezoelectric plates. The proposed technique is built upon the scaled boundary finite-element method. No kinematic and electrostatic assumptions are introduced in the derivation process. The in-plane dimensions are divided into 2D elements and the 3D geometry is obtained by

This article presents a finite element based solution of the exact governing wave equation for a stratified inhomogeneous moving media. The model is applied to a two dimensional range independent problem in outdoor sound propagation in which the ground is treated as perfectly reflecting.

Semi-analytical modeling of composite beams using the scaled boundary finite element method
Composite Structures, 2016Abstract The scaled boundary finite element method (SBFEM) is a semi-analytical method in which only the boundary is discretized. The results on the boundary are scaled into the domain with respect to a scaling center which must be “visible” from the whole boundary.

Application of semi-analytical finite element method to evaluate asphalt pavement bearing capacity
International Journal of Pavement Engineering, 2016AbstractBearing capacity is a key index in pavement management systems in many countries, which reflects the essential material properties of asphalt pavements. Many stationary measuring methods have been undertaken in the past; current assessment of the bearing capacity tends towards fast and continuous measurements at traffic speed for a network ...

Creep in microelectronic solder joints: finite element simulations versus semi-analytical methods
Archive of Applied Mechanics, 2009The presence and change of thermal stresses in solders, which are used for mounting microelectronic packages on PC-boards, will eventually lead to material fatigue. The number of cycles to failure can be predicted from empirical relations of the Coffin–Manson type provided the increments of creep strains and/or energy densities are known, for example ...

Here, some applications of the Semi-analytical (SAFE) formulation presented in a previous paper of this book (Viola et al., 2005) are shown. In order to emphasize the potentiality of the SAFE method presented, guided wave features are calculated for several isotropic waveguides immersed in vacuum.

Semi-analytical finite element method for fictitious crack model in fracture mechanics of concrete
Applied Mathematics and Mechanics, 2004Based on the Hamiltonian governing equations of plane elasticity for sectorial domain, the variable separation and eigenfunction expansion techniques were employed to develop a novel analytical finite element for the fictitious crack model in fracture mechanics of concrete. The new analytical element can be implemented into FEM program systems to solve

Journal of Sound and Vibration, 2015
Abstract An improved rail vibration model based on the semi-analytical finite element (SAFE) method has been developed, which allows multiple layers of support and the accurate shape of the rail cross-section to be considered in the modeling. Rail supports are treated as a continuous layer of equivalent springs connected to the rail foot.

INTER-NOISE and NOISE-CON Congress and Conference Proceedings
Downward refraction in the lower atmosphere, attributed to winds and temperature inversion, can enable infrasound to efficiently propagate over long distances inside acoustic waveguides. In this study, we use the semi-analytic finite element (SAFE) method to predict this effect in stratified, inhomogeneous, moving air for range-independent noise ...
