FUNDAMENTALS OF GEOTECHNICAL ENGINEERING, 5E presents the essential components of two market-leading engineering texts in one powerful combined course. The text offers a concise blend of critical information from Braja Das' leading PRINCIPLES OF GEOTECHNICAL ENGINEERING and PRINCIPLES OF FOUNDATION ENGINEERING. This valuable, cohesive book focuses on the fundamental concepts of both soil mechanics and foundation engineering without the distraction of excessive details or cumbersome alternatives. A wealth of worked-out examples and useful supporting figures help your students master key concepts and gain essential problem-solving skills. Prestigious authors Das and Sivakugan carefully balance today's most current research with practical field applications in a proven approach that has made Das' books undisputed leaders in the field. A wealth of accompanying resources, including MindTap, help reinforce the geotechnical engineering skills your students need.

"The presentation is quite good. Looking at other textbooks on the same topic I find that this book reads very well. Maybe too well, many students read ahead of the lecture and they like the style and the clarification of concepts. The examples in the book are solved in a detailed, step-by-step and logical manner. It reads very well and presents topics in a clear manner supported by quality diagrams."
"The book is very thorough and we use it for more than one course. It is very easy to follow and to understand. The book has enough examples to cover almost all the concepts. It is well organized and a student can move from one chapter to another without any confusion. The theoretical concepts are well explained. Student prefer this book over other text book because its simplicity to follow the logic of each concept. In general the illustrations in this book are easier to follow."
"The topics covered are complete. I like the additional resource materials for students and instructors. The example problems are good. … The textbook is well organized and complete. It is comprehensive, it includes new information."
