The Geosedic Finite Element is a numerical method used in geotechnical engineering to analyze the behavior of soil and rock under various loads and conditions. This method is based on the finite element method, which is a widely used technique in engineering to solve partial differential equations that describe the physical behavior of systems. The Geosedic Finite Element method is particularly useful for analyzing complex geotechnical problems, such as those involving non-linear soil behavior, large deformations, and coupled mechanical-hydrological-thermal processes.
Introduction to Geosedic Finite Element
The Geosedic Finite Element method is an extension of the traditional finite element method, which is used to analyze the behavior of discrete systems. In geotechnical engineering, the Geosedic Finite Element method is used to analyze the behavior of continuous systems, such as soil and rock, under various loads and conditions.
