The finite element method (FEM) was the tool used for modeling. A frequently encountered phenomenon in the study of pipeline systems under pres- sure is the so-called water hammer. This phenomenon can lead to great damage, start a process of plastic deformation in the tube, or even cause ...
Keywords: finite layer method; asphalt pavement structural analysis; EasyFEM; element energy projection; super-convergence 1. Introduction The analysis of stress states is of considerable importance for the design, construction, maintenance, and rehabilitation of asphalt pavements in practice. In the ...
In this article, we set up a non-intrusive procedure that yields for strict and highquality error bounds of quantities of interest in linear viscoelasticity problems solved by means of the Finite Element Method. The non-intrusive feature is achieved by introducing, via a partition of unity, ...
