Foundations of Solid Mechanics: Strain Analysis and Mohr's Circle

Understanding how materials deform under load is a cornerstone of structural, civil, and mechanical engineering. This text-based course guides you through the foundational principles of solid mechanics, focusing on the physical nature of strain and how to analyze it mathematically. You will transition from basic physical definitions to solving complex engineering deformation problems with confidence. By completing this course, you will be able to analyze material deformation under various loading conditions, perform coordinate transformations, and utilize graphic methods to evaluate strain states. What you'll learn: - Understand the fundamental concepts of strain, deformation, and normal versus shear components - Analyze the mathematical formulations of 2D and 3D strain states - Apply coordinate transformation equations to resolve strain components along different axes - Construct and interpret Mohr's circle for strain to find principal strains and maximum shear strain - Practice solving structural engineering problems using modern analytical workflows This course begins with essential terminology, establishing a clear understanding of displacement fields and strain-displacement relationships. You will then progress through transformation equations, graphical analysis techniques, and practical engineering problem-solving scenarios. This course is designed for beginners in engineering mechanics, physics students, and civil or mechanical engineering undergraduates seeking a clear, structured guide to strain analysis. No advanced background in solid mechanics is required, though a basic understanding of calculus and introductory physics is helpful.
