Enrolment information

This unit applies the engineering principles and design techniques from ENG20001 - Mechanics of Materials including force analysis in beams, shells and irregular structures, reaction forces and moments, and generating shear force and bending moment diagrams to analysis of system strength and durability. Students will apply the theoretical analysis of system strength and durability with a numerical finite element approach in this unit.

Unit description

Addresses the prediction of failure of machine components and structures by computer modelling of stresses and strains using the Finite Element Method (FEM) and by assessment of criteria to predict fracture. The lectures on FEM are focussed on modelling and interpreting results from a commercial software package, rather than the underlying mathematical theory.

Unit content

Learning outcomes

Unit Learning Outcomes express learning achievement in terms of what a student should know, understand and be able to do on completion of a unit. These outcomes are aligned with the graduate attributes. The unit learning outcomes and graduate attributes are also the basis of evaluating prior learning.

On completion of this unit, students should be able to:

use a commercial finite element package to solve linear static elasticity problems, and to critically evaluate the output

use energy methods to predict by hand the structural deflections and reactions in simple statically indeterminate structures, as a means of checking computed results

apply Linear Elastic Fracture Mechanics to analyse brittle fracture

apply the concepts of Elastic Plastic Fracture Mechanics to simple fracture situations.
