Solid Mechanics Principles: Greens Functions

This lecture covers the concept of Greens functions in solid mechanics, focusing on the solution of a point force and the displacement field caused by it. The instructor explains how to compute strains and stresses from the displacement field, emphasizing the importance of understanding the fundamental equation for Greens functions. The lecture concludes with the final result for isotropic elastic material and the significance of equilibrium problems in determining the total effect of forces. Various examples and applications are discussed throughout the lecture.
