Failure of Materials and Structures is divided into two equal components.
First the failure of un-cracked bodies is considered, where the classes of failure mechanisms are defined and examined in detail. This section compares brittle and ductile failure, plastic instability, probability based failure criteria, failure in composites and failure criteria in complex stress conditions. All these fracture and failure mechanisms are relevant to many practical engineering components.
The second set of lectures on fracture mechanics considers the failure of materials that contain pre-existing cracks. The fundamental concept of the stress intensity factor is introduced and discussed both under linear elastic and elastic -plastic conditions. Its measurement and application to fracture and fatigue problems is defined as the pre-eminent quantity in fracture mechanics. Fracture mechanics is presented within a framework of structural integrity assessments, with a particular focus on real-life problems.
Aims:
The objective of this course is to understand:
On completion of the course the student should be able to:
Students receive a 1-hour lecture each week for 20 weeks. Notes will be handed out as appropriate and note taking will also be required. Example questions will be given out; some examples will be solved during the lectures and the lecturer will state times and dates following the lecture course when he/she will be available to discuss any further problems.
The lecture course will be assessed by a 2 hour written examination.
