FATIGUE OF COMPOSITE MATERIALS

November 11 - November 15

Overview of the Program:

There has been an upsurge in the interest in composite materials in the last few decades, primarily due to high demand on material performance placed by advanced technologies. Conventional materials are unable to meet these demands. Improvements in mechanical properties, e.g. stiffness, strength and fracture toughness, are being increasingly made feasible by advancements in composite manufacturing technologies. Numerous applications of these materials can be found in the aerospace sector—significant parts of commercial and fighter airplanes are made of advanced composite materials; the automotive industry—racing car chassis, ceramic brakes, etc; the wind industry, where wind turbine rotors with diameters of more than 100 meters are now constructed using fibre-reinforced composite materials. The use of concrete composites in different civil engineering infrastructures such as bridge decks, harbours, docks, pre-stressed concrete pavements, dams, etc. has increased in the past few decades. Indeed, the applications for which composite materials are being found to be most advantageous are precisely those situations in which the degradation of strength and life by fatigue process is most likely. Fatigue damage in composite materials is a process of stochastic nature. Consequently, statistical and probabilistic concepts and methods are needed for an assessment of the safety and reliability of the composite structures under fatigue loading. This program is intended for university students, faculty and researchers having interest in the fatigue of composite materials. It will provide information regarding the fatigue behaviour of the composite materials and lead them step by step through the available methods for the modelling of the fatigue life of these materials and the prediction of their lifetime.

Program Objectives

At the end of the program, students/researchers shall be able to:
1. Understand the basic mechanisms involved in the fatigue behaviour of composite materials.
2. Understand various methodologies for fatigue life modelling and fatigue life prediction of
composite materials.
3. Use various statistical/probabilistic concepts for analysis of fatigue life data for composite
materials.
4. Use various soft computing techniques for fatigue life modelling of composite materials.
