Description

This module studies the state of stress in structural elements resulting from combined loading and examines stress and strain transformation. The fundamental equations governing beam and strut deflections are developed. Unsymmetrical bending is also addressed.

Learning Outcomes

On completion of this module the learner will/should be able to;

1.

Formulate equations governing the unsymmetric bending of beams and analyse the state of stress caused by combined loadings

2.

Transform stress and formulate equations for the analysis of principal stresses and maximum shear stress

3.

Formulate and apply equations for the analysis of plane strain and investigate failure criteria

4.

Examine the moment-curvature relationship and determine the equation of the elastic curve for beam bending

5.

Formulate the fundamental equations defining the buckling of ideal struts

6.

Perform laboratory experiments, interpret results and report findings

Teaching and Learning Strategies

Delivery of material by formal lecture, supplemented by laboratory experimental work (where appropriate) to reinforce key concepts, and augmented by independent learning. To motivate learning, and to enable learners to check their progress towards achieving the learning outcomes, problem sheets are provided.

Module Assessment Strategies

A mix of final semester examination (80%) and practical work and reporting (20%).

An overall pass mark of 40% must be obtained to pass the module.

Repeat Assessments

Learners shall repeat the failed elements. The leaner must then achieve an overall mark of 40% to pass the module
