Abaqus2Matlab: a suitable tool for finite element post-processing
TL;DR: A suitable piece of software is presented to connect Abaqus, a sophisticated finite element package, with Matlab, the most comprehensive program for mathematical analysis, and its potential to create and train neural networks is used to identify damage parameters through a hybrid experimental–numerical scheme.
Journal ArticleDOI
A comparison between friction stir welding, linear friction welding and rotary friction welding
TL;DR: In this paper, three friction welding processes are compared for temperature, stresses and strains, as well as strain rates developed in the early phases of the processes, which are essential in their successful development.
Journal ArticleDOI
OpenSeismoMatlab: A new open-source software for strong ground motion data processing.
TL;DR: The structure, algorithms and main routines of the program are explained in detail and the results for various types of spectra of 11 earthquake strong ground motions are calculated and compared to corresponding results from other proprietary software.
Journal ArticleDOI
Comparison of machine learning algorithms for regression and classification of ultimate load-carrying capacity of steel frames
TL;DR: It is found that the GTB method has the best efficiency in both regression and classification of ULF regardless of the number of training samples and the space frames considered.
Journal ArticleDOI
Optimum linear buckling analysis of longitudinally multi-stiffened steel plates subjected to combined bending and shear
TL;DR: In this paper, the optimal positions of multiple longitudinal stiffeners for steel plates subjected to pure bending, and combined bending and shear forces, are investigated by using the gradient-based interior point optimization algorithm.
