Reassessment

In accordance with the University's Code of Assessment reassessments are normally set for all courses which do not contribute to the honours classifications. For non honours courses, students are offered reassessment in all or any of the components of assessment if the satisfactory (threshold) grade for the overall course is not achieved at the first attempt. This is normally grade D3 for undergraduate students, and grade C3 for postgraduate students. Exceptionally it may not be possible to offer reassessment of some coursework items, in which case the mark achieved at the first attempt will be counted towards the final course grade. Any such exceptions are listed below in this box.

 

It is not possible to offer reassessment in group project work in this course. Students failing to complete the group project work, without good cause, will receive a Credit Refused (CR) grade and will be required to re-attend the course the following year.

Main Assessment In: December

Are reassessment opportunities available for all summative assessments? No

Reassessments are normally available for all courses, except those which contribute to the Honours classification. For non Honours courses, students are offered reassessment in all or any of the components of assessment if the satisfactory (threshold) grade for the overall course is not achieved at the first attempt. This is normally grade D3 for undergraduate students and grade C3 for postgraduate students. Exceptionally it may not be possible to offer reassessment of some coursework items, in which case the mark achieved at the first attempt will be counted towards the final course grade. Any such exceptions for this course are described below. 

Course Aims

This course aims to develop familiarity with numerical finite-element methods of structural analysis and apply them to the behaviour of beams, frames, plates and other elements of aircraft structures.

Intended Learning Outcomes of Course

By the end of this course students will be able to:

■ describe the history of the finite-element method;

■ state the basic steps in the solution of a problem by the finite-element method;

■ explain how various numerical methods seek a solution to the underlying equations;

■ analyse one-dimensional systems using linear, quadratic and cubic elements;

■ explain the relation between global, local and natural coordinates;

■ show how rectangular, quadratic and linear triangular elements can be used in two dimensions;

■ use stiffness and load matrices to analyse beams and frames;

■ explain what is meant by plane stress and give examples of systems to which it is applicable;

■ analyse the bending of thin plates based on rectangular elements with consideration of convergence of the numerical method;

■ develop the conditions under which a plate buckles, including closed-form and finite-element analysis.

Minimum Requirement for Award of Credits

Students must submit at least 75% by weight of the components (including examinations) of the course's summative assessment.
