This course presents the fundamentals of stress analysis, as well as detail stressing methods to meet the needs of aircraft stress analysis.  It is designed to introduce delegates to practical stress analysis, using real structural problems to illustrate the fundamental principles and practical techniques.  The course will be delivered via a mixture of lectures, tutorials, and hands-on sessions in the computer lab for finite element method.  There will be a session in the mechanical test laboratory to view the buckling process of stiffened panels in compression.  A stressing exercise of a representative aircraft structure will be introduced as a case study in the second week of the course to apply and test the knowledge learnt.
