Application of Dynamic Analysis in Semi-Analytical Finite Element Method. [PDF]
Materials (Basel), 2017 Analyses of dynamic responses are significantly important for the design, maintenance and rehabilitation of asphalt pavement. In order to evaluate the dynamic responses of asphalt pavement under moving loads, a specific computational program, SAFEM, was developed based on a semi-analytical finite element method.

Semi-Analytical Finite Element Method for calculating dispersion curves of a CFRP plate [PDF]
MATEC Web of Conferences, 2022 Composite Materials are widely used thanks to their mechanical characteristics. Non destructive evaluation requires knowing the exact dispersion curves to determine the propagative waves and to resolve the phase velocity of symmetrical and ...

Calculation of leaky Lamb waves with a semi-analytical finite element method [PDF]
Ultrasonics, 2014 A semi-analytical finite element method (SAFE) has been widely used for calculating dispersion curves and mode shapes of guided waves as well as transient waves in a bar like structures. Although guided wave inspection is often conducted for water-loaded plates and pipes, most of the SAFE techniques have not been extended to a plate with leaky media ...

Transient analysis of leaky Lamb waves with a semi-analytical finite element method [PDF]
Ultrasonics, 2015 We previously formulated a semi-analytical finite element technique for Lamb waves in a plate surrounded by fluids and investigated the dispersion curves and wave structures for leaky Lamb waves. Herein, this technique is extended to the calculation of transient responses both in a plate and in fluids for dynamic loading on the plate surface.

Modelling piezoelectric excitation in waveguides using the semi-analytical finite element method [PDF]
Computers and Structures, 2016 A wave-based method for modelling piezoelectric excitation is proposed.The dynamics of the actuator and mutual actuator/structure interaction are included.The method is suitable for built-up piezo-equipped structures of an arbitrary cross-section.Very good agreement is shown in both numerical verification and experimental validation.

SEMI-ANALYTICAL FINITE ELEMENT METHOD IN THE APPLICATION OF THE ULTRASONIC PROPAGATION SIMULATION
Jixie qiangdu, 2015 The semi-analytical finite element method is a method that use the finite element method to discrete the structure in the spatial domain,and then use the precise integration method in time domain to solve the problem.
