Combining regression trees and the finite element method to define stress models of highly non-linear mechanical systems

Abstract: This paper demonstrates that combining regression trees with the finite element method (FEM) may be a good strategy for modelling highly non-linear mechanical systems. Regression trees make it possible to model FEM-based non-linear maps for fields of stresses, velocities, temperatures, etc., more simply and effectively than other techniques more widely used at present, such as artificial neural networks (ANNs), support vector machines (SVMs), regression techniques, etc. These techniques, taken from Machine Lea… Show more

“…Models based on soft computing techniques normally require a larger amount of data to obtain a good model than that required for RSM (Escribano et al 2014;Lostado et al 2014). Using soft computing techniques, Lostado et al (2009) studied the contact pressure on a hub where it was mounted a double-row TRB. In this case, different types of regression techniques were used to predict the distribution of the contact pressures on the hub as function of a preload, a load and a friction coefficient.…”

“…Lostado et al. 12 studied the contact stress on a hub on which a double-row tapered roller bearing. In this case, regression models were developed in order to predict the distribution of contact stresses on the roller as a function of the preload, the load, and the friction coefficient in a three-dimensional FE model.…”

“…FEM is known to be a powerful tool to design and optimize mechanical devices, as well as different human body parts or even human prostheses for foot, knee or hip. This is especially true when their behavior is nonlinear [ 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 ]. Over the years, several researchers have used the FEM to study the mechanical behavior of the human IVD.…”
