Textbook of Biomechanics

0.0

This textbook is meant for students of multiple disciplines like biomedical engineering, physical education and rehabilitation engineering. It encapsulates the author’s 13 years of experience in teaching the subject to students of interdisciplinary studies of biomedical engineering. The book includes the basic mechanics of statics and dynamics to help students of other disciplines who join biomedical engineering at the postgraduate level. What makes the book truly interdisciplinary is the substantial information related to biology, for example, hard and soft tissue characteristics and their replacement materials. Basics of fluid mechanics and their application in cardiovascular and respiratory systems are explained without using medical jargon to make them comprehensible to engineering students. A glossary of biomechanics is also included at the end of the book for easy referenceof key terms. This book is written to make the subject interesting and therefore avoids excessive use of high-level mathematics. The varied and extensive examples and exercises illustrate the principles clearly. Textbook of Biomechanics will be suitable for first-time learners both at the undergraduate and postgraduate level.
