Module information on this degree can be found below, separated by year of study.

The module information below applies for the current academic year. The academic year runs from August to July; the 'current year' switches over at the end of July.

Students select optional courses subject to rules specified in the Mechanical Engineering Student Handbook,  for example at most three Design and Business courses. Please note that numbers are limited on some optional courses and selection criteria will apply.

Computational Continuum Mechanics

Module aims

The course is designed to introduce the fundamentals of continuum mechanics and to demonstrate how problems in continuum mechanics can be solved using numerical techniques. Particular attention is paid to the theory and implementation of the finite element method. The course provides the theoretical basis for Masters level courses on applications of finite element methods (FEAA) and finite volume method (CFD) and is a companion course to ME3 Fluid Mechanics (FMX) and ME3 Stress Analysis (SAN).

ECTS units:    6   
Contributing to Course Elements: 6 to ME3-LCTVS or ME4-LCTVS

Learning outcomes

On successfully completing this module, students will be able to:

  • Discuss the basic concepts of continua, and conservation and constitutive laws, in terms of deformation, strain and stress
  • Restate simple problems - involving, e.g., heat transfer, stresses, deformation and/or flow - in continuum mechanics terms
  • Describe the fundamentals of the Finite Element (FE) method
  • Solve simple continuum mechanics problems using analytical methods
  • Define more complex problems in a form suitable for solution using FE methods
