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. At the completion of the course, students should:

Lectures are supported by problem-solving tutorials developing material covered in lectures, FE tutorials and Lab classes.

The required time commitment is 52 hours attendance at lectures and tutorials, approximately 50 hours of revising course material and 40 hours completing assignments.

The Solid Mechanics module is worth 50% of the total course assessment and the Materials & Structures module worth 50% of the total course assessment

The Final exam will be scheduled in week 15 or 16. Half of the exam will be for the Solid Mechanics module and half will be for the Materials & Structures module.

The following tables are an outline of the assessment for each module of this course. Please note that while every effort has been made to ensure that this information reflects an accurate plan, the coordinator and lecturers have the right to make changes that ensure the continual improvement of the course. Any such changes will be made clear during the lectures and via MyUni.

Solid Mechanics module:

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

Materials & Structures module:

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

Finite Element (FE) Laboratory

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

Experimental Laboratory

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

Exam

The examination is intended to assess the student’s knowledge and understanding of the course material. The final examination is open-book.

Solid Mechanics module:

Assignments

These 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.

Quizzes

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

Materials & Structures module:

Assignments

These are problem-solving exercises covering the topics from this module of the course.

Project

The students are required to carry out a literature review (mini research) on the use of composite materials in aerospace applications. There would be specific topics for students to choose from.

Quizzes will be collected at the end of the in-class tutorials.

All other assignments and reports must be submitted as a hard copy (unless stated otherwise) accompanied by an assessment cover sheet available near the assignment submission area. These must be placed the labelled box 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.
