The primary aim of the course is to provide students with the basic skills and knowledge required to analyse displacement field, stress, strain and failure in deformable solids using analytical solutions and the Finite Element Method. The course develops an understanding of the mechanics of complex practical situations through the establishment and solution of appropriate boundary value problems. It will also give students an overview of important structural engineering design philosophies. The course forms a foundation to allow more effective interactions with civil and structural engineers during their professional careers. Students will carry out design tasks, supported by quality assurance and verification strategies associated with risk management as used in industry.

At the completion of the course, students should:

Solid Mechanics Part worth 50% of the course assessment

All assignments are due by 5pm on the due date. Details of each task are tabulated below.

Structural Design Part worth 50% of the course assessment

All assessment tasks (except the final exam) require groupwork, the same mark will be allocated to all group members and will be based on group output only. Group processes are not assessed explicitly in this course. All members in a group are expected to contribute equally to the overall task. In cases of unequal contributions to groupwork, students should complete a self-and-peer assessment form.

Compulsory attendance at FE tutorials and Lab classes, minimum result required for FE and Lab classes is 50%.

Solid Mechanics part

Assignments 1 - 3

There are problem-solving exercises. These problems will be discussed in class in detail before the due date. Example problems with full worked solutions will be considered in class and the solutions of the assignment’s problem will be available on MyUni.

FE Tutorials Report

This is an individually written assignment on the FE modelling part of the course and will involve problem-solving exercises. The timetable for FE tutorials will be available on MyUni in the beginning of semester.

Lab Classes Report

This is a group assignment on the experimental study part of the course. The timetable for the lab classes will be available on MyUni in the beginning of semester.

Quizzes

Quizzes are individual in-class assignments and this includes problem-solving exercises to be completed in normally 45 min with full worked solutions to be available on MyUni.

Structural Design part

All assessment tasks (except the final exam) require groupwork. The objective is to provide students with the experience of working in groups to undertake open-ended design tasks. These types of problems reflect the challenges presented to engineers in industry, whereby efficient designs must be supported by rigorous quality assurance strategies in order to mitigate risk. The truss design involves conceptual, preliminary and final design procedures. This is supported by the preparation of engineering calculations and drawings, along with the construction and testing of a model truss to determine the robustness of the design. The aim is to minimise the strength-to-weight ratio of the structure to maximise efficiency. The reinforced concrete design involves design calculations and an investigation into the multi-disciplinary aspects of the design and construction of a real-life building. All aspects of the course include quality assurance strategies including self and peer-checking, and verification.

Solid Mechanics part

Quiz will be collected at the end of tutorial.

All other assignments must be submitted as a hard copy accompanied by an assessment cover sheet available from S116 or near the assignment submission area. These must be placed the labelled box located on level 2 of Engineering South Building.

Late assignments will be penalised 10% per day. Extensions for assignments and reports will only be given in exceptional circumstances and a case for this with supporting documentation can be made in writing after a lecture or via email. Hard copy assignments will be assessed and returned in 2 weeks of the due date. There will be no opportunities for re-submission of work of unacceptable standard.

Structural Design part

Assessment tasks (except the final exam) must be submitted as a hard copy accompanied by a signed assessment cover sheet. These must be placed in the labelled mail box adjacent to room N136, Engineering North (i.e. front office of the School of Civil, Environmental and Mining Engineering).
