Based on the typical structure of solid mechanics curricula, "Part II" usually transitions from the mechanics of simple structural elements (bars, beams, and shafts covered in Part I) to 3D Stress, Strain, and Constitutive Laws. While there are several textbooks by authors named Kelly (most notably Michael W.D. Kelly, Introduction to Solid Mechanics), the "Part II" designation almost universally covers the following core topics.
Solids can exhibit two types of behavior: elasticity and plasticity. Elasticity refers to the ability of a solid to return to its original shape after the removal of external loads. Plasticity, on the other hand, refers to the permanent deformation of a solid under external loads. solid mechanics part ii kelly pdf
To understand the value of the PDF, one must understand the syllabus it encapsulates. Based on the standard course outline for Engineering Science 220 (or similar), Part II breaks away from simple statics and moves into core mechanical behavior. Based on the typical structure of solid mechanics
