This excellent text is the result of over 30 years of teaching university courses on continuum mechanics. The author's lecture notes have been adopted by professors at other universities and now these notes have been refined and converted into a book. It serves as a learning tool for all levels of engineers and advanced engineering students. It features heavily solved examples and exercises that benefit the reader by clearly demonstrating the ideas discussed; these will form about 60% of each chapter. This book provides an up to date, practical explanation of continuum mechanics that will appeal to students and practising engineers alike. It features many solved examples and exercises that demonstrate the ideas presented. It correlates ideas with concepts learned in lower level undergraduate classes, in order to make the material more accessible and comprehensible to a wider range of students. It is written in a clear and easy-to-read style and provides a thorough overview of non-linear continuum mechanics. It features applications using numerical calculation tools (for example in electronics, materials science and surgery), with mathematical coverage geared towards engineering students. This publication is ideal for third year undergraduates/graduates, researchers in civil and mechanical engineering, manufacturing engineering, aerospace and geological engineering and also applied maths advanced undergrad and graduate students, and practising engineers.
