摘要: Publisher Summary The chapter presents a comprehensive comparison of laminate failure models, which is established to assess the state of-the-art in modeling technologies on an international level (known as Worldwide Failure Olympics Exercise). It represents one contribution (called Part A Exercise) exercise, where predictions for response and behavior various laminates, such specific carbon- glass-fiber-reinforced epoxy laminates under broad range loading conditions are made. The describes method predicting nonlinear stress/strain composite laminates. Predictions based incremental formulation well three-dimensional laminated media analysis coupled with progressive-ply methodology. Nonlinear lamina constitutive relations composites represented using Ramberg–Osgood equation. Piece-wise linear increments stress strain calculated superimposed formulate overall effective response. Individual ply stresses strains monitored calculate instantaneous stiffnesses solution establish levels. approach allows unloading discrimination potential modes failure. 14 different cases. cases include prediction vs. responses initial final envelope multiaxial loading.
