Finite-element and semi-analytical study of elastic wave propagation in strongly scattering polycrystals [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2022 This work studies scattering-induced elastic wave attenuation and phase velocity variation in three-dimensional untextured cubic polycrystals with statistically equiaxed grains using the theoretical second-order approximation (SOA) and Born approximation models and the grain-scale finite-element (FE) model, pushing the boundary towards strongly ...

Guided wave propagation in thermal media through the semi analytical finite element method [PDF]
Journal of Theoretical and Applied Mechanics, 2016 In this paper, the issue of the estimation of wave propagation characteristics in thermal media is dealt with. A formulation, named the Thermal Semi Analytical Finite Element, based on the semi analytical finite element approach coupled with the thermal effect is offered. Temperature variations affect the mechanical properties of the waveguide.

A Semi-Analytical Finite Element Approach in Machine Design of Axisymmetric Structures [PDF]
, 2011 In the last decades, finite element (FE) method has proven to be an efficient tool for the numerical analysis of twoor three-dimensional structures of whatever complexity, in mechanical, thermal or other physical problems. It is widely recognised that computational cost (as time and computer capability) increases greatly with structure complexity ...
