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.

Unlike Part I, which focuses on elastic (reversible) behavior, Part II introduces Plasticity Theory to explain permanent deformation. Academia.edu Yield Stress
The "Solid Mechanics Part II Kelly PDF" is not available from a single official source but is widely shared on academic platforms, making it accessible to students.
Dr. P.A. Kelly (or the academic team behind the "Kelly" notes) from the University of Auckland produced a legendary series of lecture notes. While "Part I" typically covers statics, basic beam theory, and torsion, is where the real depth begins. The document is mathematically rigorous, built on the
Websites dedicated to OER like OpenStax, MIT OpenCourseWare, or similar initiatives might offer similar materials for free. However, finding an exact match might be challenging.
What specific or chapter from Part II are you currently focusing on?
The Kelly PDF is not for beginners. It is for students who have already passed the introductory course and are frustrated by textbooks that skip derivations. Kelly shows you the mathematical scaffolding. Plasticity, on the other hand, refers to the
Occasionally, the notation differs from standard textbooks (e.g., tensor vs. engineering shear strain), but once you acclimate, it is arguably clearer than most commercial texts.
Its value is greatly enhanced when used as part of the complete series, creating a powerful and structured learning pathway. For any student of engineering or applied mechanics, tracking down this PDF is a highly worthwhile endeavor.
