2.074: Solid Mechanics: Elasticity

Fall | Graduate | 12 Units | Prereq: 2.002 and 18.03

Introduction to the theory and applications of nonlinear and linear elasticity. Strain, stress, and stress-strain relations. Several of the following topics: Spherically and cylindrically symmetric problems. Anisotropic material behavior. Piezoelectric materials. Effective properties of composites. Structural mechanics of beams and plates. Energy methods for structures. Two-dimensional problems. Stress concentration at cavities, concentrated loads, cracks, and dislocations. Variational methods and their applications; introduction to the finite element method. Introduction to wave propagation. 

Fall 2020 Update: Fully Remote Classes - 2.074 will be an online subject. Lectures, recitations and office hours will be synchronous (live). Recordings of either the lectures, or asynchronously pre-recorded videos covering the same material, as well as comprehensive lecture notes will be available. I will also have a few 1-on-1 meetings with each student over the semester. Assessment will be based primarily on weekly problem sets. The topics covered will be similar to those in past years with the first two thirds being on nonlinear elasticity of “soft materials” and the last one third on linear elasticity. Some topics will be covered based on student interest. Please email me at rohan@mit.edu if you have questions, suggestions or concerns.
