## Description

Strong, weak, Galerkin, and matrix forms of differential equations; accuracy and characteristics of finite element solutions; isoparametric elements; 1d, 2d, and 3d linear elasticity problems; dynamic analysis of structures with lumped and distributed mass; introduction to nonlinear analysis.

The finite element method is a numerical method ubiquitously employed to solve boundary value problems arising in a wide range of fields, e.g. structural mechanics, heat flow, advection-diffusion, and electromagnetics problems.

This course covers the mathematical underpinnings of the finite element method, and its application to solve structural mechanics and heat flow problems. Although emphasis is on the linear static analysis of continuum and framed structures, dynamic analysis is introduced towards the end.

This course caters to Structural, Geotechnical, Mechanical, and Fire engineers. It is designed to enable students to conduct robust analyses using commercial software packages, and to confidently interpret the results.

## Learning Outcomes

1. Develop the finite element formulation for 1d, 2d, and 3d boundary value problems.
2. Design smooth, continuous, and convergent finite element meshes to discretise the problem domain.
3. Apply the finite element method to compute approximate solutions for structural mechanics and heat flow problems using efficient numerical solution algorithms.
4. Apply the finite element method to analyse linear models of continuum and framed structures under external static and dynamic loads.
5. Apply the finite element method to compute the modal frequencies and dynamic mode shapes of a structural model.
6. Interpret the accuracy of the analysis results in light of the factors like the conditioning of the system, the order of numerical integration employed, the quality of the mesh, and the influence of mesh refinement.
