Any object subjected to a load, whether it is a force or a thermal load, will experience a stress and a strain.  Understanding how a load causes stress and strain is essential for solving engineering problems.  Being able to determine the maximum stress and strain and their locations, is imperative for evaluating and optimising designs. Building on knowledge of structures and equilibrium of forces gained in Solid Mechanics, this unit will allow students to analyse the effects of axial, bending, shear, torsional and thermal loading on mechanical structures and elements using mathematical techniques and computer simulations.

Learning Outcomes

On successful completion of this unit, students will be able to:
  1. Formulate and evaluate solutions to engineering problems of 3-dimensional stress and strain, especially fundamental problems of elasticity in mechanical engineering.  
  2. Collaborate and investigate real-world engineering problems of stress and strain.  
  3. Present clear and coherent exposition of mechanical engineering knowledge.  
  4. Analyse and interpret problems, results and their significance.  

Assessment

Assessment type Description Grade
Portfolio Computer modeling of stress and strain - Group (approx. 2,000 words) 15%
Case Study Case study and portfolio of evidence. Mechanical engineering application - Group (approx. 2,000 words) 25%
Examination Restricted Open Book Examination (3 hours) 60%
The reports and case study are undertaken by groups, and assess a student's ability to problem solve and interact in a team situation. The examination focuses upon the individual student's ability to demonstrate his or her in-depth understanding of specialist bodies of knowledge within the engineering discipline and apply established engineering methods to complex engineering problems, as defined in Engineers Australia competencies 1.3 and 2.1. As the examination is the one clear way by which these competencies can be assessed on an individual basis, students must achieve a minimum mark of 50% in the examination (and 50% in the overall unit assessment) in order to pass the unit.
