Lecture
This lecture covers the analysis of deformations in solid mechanics, focusing on small strain theory and kinematics. The instructor explains the decomposition of deformations, the total deformation gradient, and the concept of compatibility conditions. The lecture also delves into the interpretation of geometric changes, volume changes, and the strain tensor. Emphasis is placed on understanding the relationship between displacement components and strain components, as well as the importance of maintaining compatibility between neighboring regions in a body.
