Accuracy of semi-analytical finite elements for modelling wave propagation in rails

Author: Andhavarapu, EV ; Loveday, Philip W ; Long, Craig S ; Heyns, PS Date: Jan 2010 The semi-analytical finite element method (SAFE) is a popular method for analysing guided wave propagation in elastic waveguides of complex cross-section such as rails. The convergence of these models has previously been studied for linear ... Read more
Numerical verification of an efficient coupled SAFE-3D FE analysis for guided wave ultrasound excitation

Author: Long, Craig S ; Loveday, Philip W ; Ramatlo, Dineo AM ; Andhavarapu, EV Date: Sep 2018 Numerical verification of a method to simulate piezoelectric transducers exciting infinite elastic waveguides is presented. The method, referred to as SAFE-3D, combines a 3D finite element (FE) model of a transducer with a 2D semi-analytical ... Read more
