Abstract text:
The approach towards solving problems related to the construction environment is currently facilitated by the existence of advanced computers and programs developed specifically for different engineering branches. Finite element based programs are powerful tools capable of solving even the most complex engineering structures. In this context, the user dictates the quality of the results obtained from the numerical analysis. For this reason, an essential aspect for obtaining representative results for the studied problems is the user’s understanding of the mathematical basis and the stages involved in the numerical analysis process. Given that the mathematical basis is represented by the established laws of continuum mechanics, this article aims to present the process of determining the state of stress and strains of a continuous body in an easily understandable way, providing in the end an example of calculation in the field of geotechnical engineering. Understanding these basic principles is fundamental in the numerical modelling of engineering problems.
