Engineering Fracture Mechanics

In this e-Book, a novel attempt is made to smoothly integrate experimental results in real-time to have laboratory experience in a lecture class.

The e-book covers exhaustively the famous techniques like Photoelasticity and Strain gauges and provides a decent exposure to Moiré, Brittle coatings, Holography, Speckle Methods, Thermoelastic Stress Analysis, Digital Image Correlation, Caustics and Coherent Gradient Sensor. In addition, the book has the most recent and state of the art and exhaustive treatment of Digital Photoelasticity.

It has come about from teaching the course to graduate and undergraduate students for the last 20 years at IIT Kanpur and IIT Madras. The student response , with critical inputs has greatly influenced the development of the course in many ways.

Wholesome engineering education is possible only if students are exposed to various experimental techniques. It is seen in many Institutions, that when a faculty with experimental background retires, the courses also vanish from the curriculum! This is because teaching experimental methods needed special expertise.

The book is interactive and even faculty/engineers with analytical or numerical background, with little practice can comfortably handle the basic experimental course and with time there is a chance that they too get interested in experimental work and become asset to their organizations!

The e-Book not only provides basic concepts on understanding and appreciating the data interpretation from various techniques but also provides detailed practical information such as casting of photoelastic sheets and pasting of strain gauges to implement the techniques in the laboratory.

Usage of this e-book for various courses

Apart from a three credit (42 lectures) first level course on Experimental Stress Analysis, with judicious planning, one can use the material in the book in a variety of ways to suit different audiences like a

• one day course to senior executives on Experimental Methods (Chapter 2),
• one day course on Experimental Evaluation of Fracture Parameters (Selected portions of Chapter 2, Chapter 12),
• one day course on Strain Gauge Based Transducers (Chapter 8, Selected portions of Chapters 6 and 7)
• three day workshop on Strain Gauge Technology (Selected portions of Chapters 6,7 and 8),
• 2 credit course (28 lectures) on Advanced Experimental Methods (Chapters 2, 10 and 11),
• 2 credit course on Digital Photoelasticity (Chapter 5 and Selected portions from Chapters 1, 2 and 3),
• 2 credit course on Strain Gauges (Chapters 1, Selected portions from Chapter 2, Chapters 6, 7, 8 and 9),
• 3 credit course on Photoelasticity (Chapters 1, 2, 3, 4 and 5) and so on.
