With Biomechanics: Motion, Flow, Stress, and Growth, the premier bioengineering scientist Y.C. Fung concludes a discussion first introduced in his seminal work, Biomechanics: Mechanical Properties of Living Tissues, and further articulated in Biomechanics: Circulation. This third volume not only stands alone as a comprehensive survey of the broad field of biomechanics, but also complements the explorations of the first two volumes, maintaining its emphasis on methods of classical engineering as applied to biological and physiological phenomena. While consistently recognizing the importance of historical precedence and perspective, Fung presents the most contemporary literature and the latest thinking in biomechanics in thei increasingly complex interdisciplinary subject. Considered here are 1.) the mechanics of body movement; 2.) the flow external to an animal in motion, and the internal flow of blood, gas, water, and other body fluids; 3.) the stress and strain, and the strength, trauma, and tolerance limits of tissues and organs; and 4.) the growth and change in living organisms in response to biomechanical principles. A generous number of problems to be solved and a carefully selected list of references are especially useful and should help to stimulate thought and discussion among advanced undergraduates, graduate students, and others with an interest in bioengineering and medicine.
