Lecture
Nonlinear Analysis of Structures: Geometric Nonlinearity
Description
This lecture covers the analysis of structures with large deformations, focusing on the effects of geometric nonlinearity. Topics include large rotations in finite element analysis, examples of beam and dome structures, stress stiffening in thin membranes, and practical considerations for modeling structures undergoing large displacements. The lecture also introduces uni-axial constitutive relationships, backbone curves, hysteresis laws, and the use of OpenSees for structural simulations.
