Learning outcomes
After successfully completing this course, student will be able to:
1. Understand energy-method solutions for structural problems.
2. Analyse stiffened panels and tension field beams;
3. Understand the principles of stressed skin construction as applied to aerospace structures;
4. Carry out analysis to determine bending, shear and torsion of open and closed thin walled aerospace structures;
5. Carry out stress analysis of aerospace structures;
6. Determine and analyse the effects of structural constraints on aerospace structures.

Skills outcomes
On completion of this module students will have acquired the following skills: analytical, problem solving, mathematical derivations and solutions.

Private study

Students are to spend on average 0.5 hours preparation/revision for each lecture (17 hours total), approximately 50 hours of work for the one piece of coursework, 48 hours for the exam preparation and 2 hours to do the exam.

Opportunities for Formative Feedback

Throughout the course there will be number tutorial classes within the lectures, together with one piece of coursework mid-course to guarantee appropriate feedback before the end of course. Formative feedback will be provided for all work.
