Element Method

A new analytic-experimental method for describing crack breathing and obtaining shaft local stiffness change is presented. A generalized nonlinear formulation using the finite element method, which can be widely used for both horizontal and vertical cracked shafts, is derived. Some results previously explicited in other studies are confirmed and clarified. This advanced model can serve as a solid basis for further studies.

Abstract The frequent occurrence of floods recently has motivated discussions by experts on reviewing the safety of flood protection structures. The simulation of flood discharges belongs among transient flow tasks. Due to the randomness of the phenomenon, as well as the often unknown geological composition of the environment in which the flooding occurs, this question has become very complicated. The finite element method (FEM) is one of the methods for reviewing risk factors endangering the stability of hydraulic structures. In this article the application of FEM is mentioned in assessing the stability of the subsoil of the Borša polder in Slovakia.
