A Numerical Approach for Calculation of Characteristics of Edge Waves in Three-Dimensional Plates
(2020-09-19)Surface waves have been extensively studied in earthquake seismology. Surface waves are trapped near an infinitely large surface. The displacements decay exponentially with depth. These waves are also named Rayleigh and ... -
Numerical determination of plastic collapse loads for sections under concentrated transverse forces
(2017-09-13)Structural steel design codes generally use design methods requiring the determination of two key reference loads: (i) the plastic collapse load and (ii) the elastic buckling load. Using these two key reference loads, the ... -
The Numerical Inversion of the Laplace Transform in a Multi-Precision Environment.
(2022-05-23)This paper examines the performance of five algorithms for numerically inverting the Laplace transform, in standard, 16-digit and multi-precision environments. The algorithms are taken from three of the four main classes ... -
