the effect of boundary conditions on the solution of the inverse problem of identifying the geometry and location of a cavity inside an elastic solid body using displacement measurements obtained from a tension test is investigated. the boundary elements method (bem) coupled with the genetic algorithm (ga) and the conjugate gradient method (cgm) are implemented in this identification problem. a...

this paper presents an overview of model updating and particularly its application for updating of frame model. in this article a mathematical model of the frame was produced with finite element method. the frame was subjected to hammer modal testing. then the results of the modal testing were compared with those predicted with the model. this comparison revealed discrepancies between these two...

The present review paper has several objectives. Its primary aim is to give an idea of the general features virtual element methods (VEMs), which were introduced about a decade ago in field numerical for partial differential equations, order allow decompositions computational domain into polygons or polyhedra very shape. Nonetheless, also addressed readers who have already heard (and possibly r...
