Overview

The subtle changes in both properties and performance quantified either in terms of endurance, durability and damage tolerance are the salient phenomenon of fatigue. With rapid strides in the development and emergence of spectrum of advance material s and concurrent advancement in fracture machine methodologies, the concept of the sustained performance of the fatigue and ensuing fracture behaviour or failure response has grown to emerge as a major area of the scientific and applied research cross-pollinating a spectrum of the disciplines to include materials science and engineering ,the aerospace engineering ,engineering machines, biomechanics and applied physics. With the increasing demands imposed on high performance materials the need for fatigue research has progressively gained increased importance. This course structured with the purpose of presenting the principles and applications of the fatigue and fracture to materials and structures.

Objectives

The design of structures, spanning arrange of size and to include both performance-critical and non-performance critical, must be both safe and sound to ensure the desired longevity or service life intended for the structure. Structures must be made from the material that can safely resist aging, withstand load spanning both static and dynamic (fatigue), environment-included degradation to include both oxidation and corrosion and even wear. Attendees will learn how to specify, select and economically affordable, mechanical property conductive materials that will ensure long life for the intended structures while concurrently assuring a failsafe criterion. This course would provide the option of the selecting alternative materials to the traditionally used choice for structures of need and interest and having far reaching practical application.
