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:
The unit will be delivered through material including videos and narrated lectures which will be made available to the students with support online.
The unit will be assessed using a single examination. Feedback will be provided to students during the year.
