Credit points:	03
Year:	2006
Student Contribution Band:	Band 2
Administered by:

Topics include: General overview and introduction to discrete systems and constraints. Enforcing constraints in FE system: review of methods and derivation of augmented system for Penalty, Lagrangian, Perturbed Lagrangian and Augmented Lagrangian constraints. Basic review of explicit solution algorithm. 2D node-edged penalty algorithm for explicit applications. Basic review of implicit solution algorithms. 2D node-edge penalty algorithm for implicit applications. Guidelines for modelling implicit contact. 2D node-edge penalty algorithms (modelling frictional slip). Introduction to finite/discrete element methods. Spatial sorting algorithms. Other discrete element representations.

Learning Outcomes

• To describe algorithms for numerically modelling the contact and friction conditions arising from the interaction of discrete bodies where the bodies may be represented by finite elements or rigid bodies.

Graduate Qualities

• The ability to define and to solve problems in at least one discipline area;
• The ability to calculate, produce, interpret and communicate numerical information;
• The ability to select and use appropriate IT tools;
• The ability to use a variety of media and methods to retrieve, analyse, evaluate, organise and present information;
• The ability to learn independently and in a self-directed manner.
