StressCheck Tutorial: Linear vs Nonlinear Results for a Single Lap Joint
Abstract: Comparison between linear, material nonlinear (plasticity effects) and general nonlinear (plasticity + geometric nonlinear effects) for a single lap joint under uniaxial load. Large deformations result for the linear analysis, including unrealistically large rotations at the adhesive, indicating geometric nonlinear analysis is required to represent the solution.
