Description

Axial, torsional, transverse and bending loads; compound states of stress, principal stresses and strains; basic theories of failure for ductile and brittle materials; buckling including local buckling effects; basic energy methods; impact theory.

The primary objective of this course is to develop an understanding of stress and strain with an engineering application to common structural elements such as beams and bars.

The course will develop basic competency in the application of the methods of ‘mechanics of materials’ to problems in mechanical engineering.  The course serves as a foundation for subsequent, required courses (for Mechanical Engineers): ENME203 (Dynamics and Vibrations), ENME307 (Performance of Engineering Materials) and ENME302 (Computational and Applied Mechanical Analysis).

Assessment

Option 1:
2 x Test Out of Hours (30% each); Homework (10% total); Final Exam (30%)

Option 2:
2 x Test Out of Hours (15% each); Homework (10% total); Final Exam (60%)

The assessment weighting that yields the highest grade for each student individually will be used automatically.  It is strongly suggested that you take option 1 - it is very difficult to make 50% from 60% of the marks!
