SHORT COURSES AT COLLEGE OF AERONAUTICAL ENGINEERING 1. MATERIAL FAILURE ANALYSIS COURSE Purpose and Background PEC sponsored short course on Material Failure Analysis is being arranged to create an understanding on how and why materials fail and factors that contribute to such failures. It bridges a gap between theoretical concepts and their application in field. Material Failure Analysis is an important engineering function that can occur due to a variety of reasons Design errors Improper material Improper manufacturing process Unforeseen operating conditions Improper maintenance A thorough understanding of Material failures can enable engineers to improve on their design, manufacturing and maintenance practices. Purpose of this course is to equip engineers with adequate understanding of this subject so that they can efficiently apply their engineering knowledge on practical cases they encounter in field / industry. With the understanding of this subject, engineers can improve their design / manufacturing and maintenance procedures to provide a better and safer product to their clients. Learning Objectives & Benefits This course has been designed to familiarize engineers with modern trends and techniques available for material failure analysis. In this course, in addition to metals such as Aluminum and Ferrous alloys, a substantial part has been dedicated for other advance materials such as polymers and polymer based composites. Advance concepts such as low and high cycle fatigue, thermal and residual stresses are also introduced. The last part of the course covers modern material analysis and forensic techniques 1 such as metallography and fractography, using modern scientific tools like Scanning Electron Microscope (SEM).

FATIGUE AND FRACTURE COURSE Purpose and Background PEC sponsored short course on Fatigue and Fracture is being arranged to understand why materials fail without any prior warning. Fatigue in engineering components and materials refer to the initiation and development of cracks in the component, as a result of cyclic loads. There are numerous cases where a component that has been operating perfectly satisfactorily, suddenly fails catastrophically due to development and propagation of fatigue cracks. In engineering, we come across components / structures in which flaws are inevitably present and which are subject to operational stresses. Fracture mechanics analysis, coupled with appropriate inspection procedures, provides a rational and quantitative method for enabling a component to be kept in service safely, at least until a scheduled inspection or maintenance outage, when repair can be affected, with minimal loss of production. Fracture mechanics is not only a powerful tool for rational evaluation of NDT flaw indications, but is also invaluable in design, materials selection and failure analysis. Purpose of this course is to build an understanding of this subject among engineers so that they can develop a systems and checks whereby the structural integrity of engineering systems can be assessed for their fitness. Learning Objectives & Benefits This course has been designed to familiarize engineering with fracture of engineering materials with special focus on fracture under fatigue loading. Theory of fracture mechanics covering stress concentration, modes of fracture, basic stress analysis, low cycle/high cycle fatigue and creep have been covered.

A significant portion of this course also involved experimental work involving UTM, bending fatigue testing and metallography. 3 Course Breakdown Module Topics 1 (Materials and Heat Treatment) Micro Structure Phase Diagrams Heat Treatment 2 (Fracture Mechanics) Fatigue and Creep Failure / Yield Criterions Aero Elasticity Fracture Mechanics 3 (Failure Prevention Techniques) Prediction and Basic Stress Analysis Stress-Strain Curves Elements of Machine Design Philosophy of A/C Design NDI Techniques 5 (Fractography / Metallography) Specimen preparation / etching Optical microscopy Introduction to SEM 5 (Case Studies) Case Study I Case Study II Lab visits and demonstration 4 3. STRUCTURAL HEALTH MONITORING (SHM) Purpose and Background PEC sponsored short course on Structural Health Monitoring (SHM) is being conducted to familiarize engineers with latest trends in Non Destructive Evaluation (NDE) methods for monitoring and ensuring structural integrity. It has extensive application in aerospace, mechanical and civil engineering. SHM is a system with the ability to detect and interpret adverse “changes” in a structure in order to improve reliability and reduce life cycle costs. In SHM, structures are continuously monitored during their use by embedded or attached Non Destructive Evaluation sensors. SHM is being used extensively in structural integrity and structural life enhancement programs in aviation industry. For aircraft applications, the use of SHM technologies for future aircraft will not only enable new possibilities for maintenance concepts but will have a significant influence on design concepts and assembling technologies. SHM is expected to be one of the key technologies for controlling the structural integrity of future aircraft, providing both maintenance and weight saving benefits. Some of the advantages over conventional NDE inspection include reduced inspection down time, elimination of component tear down, and potential prevention of failure during operation. SHM is likely to be used in identifying failures in aircraft, which would also be a boon to the commercial aircraft industry. Learning Objectives & Benefits This course has been designed to familiarize engineering officers with modern trends and techniques available for structural health monitoring of aerospace structures.

Project Management Workshop Purpose and Background PEC sponsored 01 week workshop on Project Management at CAE is being organized to address the basic concepts of project management with practical hands on training on Microsoft Project Management Software. Project is (usually) a one off set of interrelated activities or tasks which ends with a specific goal or target being reached. Common characteristics of a project include: • A set of non routine tasks to be performed in a certain sequence. • It is goal orientated with measurable achievements in mind. • There will be various constraints to work within. These may be financial, resource, legal, ethical, environmental, quality and/or time based. For example, there will be a limited set of resources with which to perform the tasks. Some of these resources may be shared with other concurrent projects. • It will involve people: their management, motivation, knowledge and expertise. This workshop familiarizes the managers, consultants, and academia in defining, planning, scheduling and controlling of the tasks which must be completed to achieve their goal(s). Defining and planning help you work out what has to be done and by whom. Scheduling means you know when you have to do it and controlling is necessary because some things will not turn out as planned!
