RATIONALE:
Numerical methods have been playing an increasingly important role in Geotechnics. Among them the Finite Element Method (FEM) stands out by its versatility and current design practice relies on the use of commercial software based on it. It is therefore imperative, on the one hand, to explain the theoretical basis of the FEM and, in addition, to develop the required skills and judgement for its use in geotechnical applications.
OBJECTIVES:
Introduction to the application of the Finite Element Method to the analysis of geotechnical problems. The presentation of the theoretical fundamentals of the finite element method is complemented with the use of commercial programs for solving geotechnical problems.
KNOWLEDGE
Define the FEM procedures for obtaining an algebraic equation system that provides an approximate numerical solution for the governing differential equations of the physical phenomenon under consideration.
UNDERSTANDING Identify the fundamental algorithmic aspects of FEM in various geotecnically oriented application areas.
APPLICATION Demonstrate the ability to apply the Finite Element Method (FEM) to solve geotechnical problems.
ANALYSIS Use FEM parametric studies to assess the relative weight of various factors on the quality/efficiency/safety/cost of the required solution.
SYNTHESIS Extract from the numerical studies clues for the optimization of the solution.
JUDGEMENT
Criticize the results obtained by FEM based on knowledge of factors affecting the quality of the solution.
ENGINEERING DESIGN COMPETENCIES
Train the ability to deal with FEM in order to use it efficiently as a tool in geotechnical design on curricular units that develop this component.
