With the development of various machines, the structures of most of them being far from simple, the necessity for testing of materials has arisen. As a result, Testing of Metallic Materials has become a common engineering subject. This book deals with the testing techniques and calculations of different strengths, values etc. of various metallic materials. Examination of the test specimens and interpretation of test data will provide a deep insight into the metallurgical aspects of the materials. The essence of the Second Edition is to provide an insight into the methods of testing. The chapter dealing with Fracture Mechanism is elaborated to give a better perspective of failure from a physical metallurgical concept. Elementary ideas regarding grain structure and criticals resolved shear stress of single crystals under load, are provided.
