Modeling compression failure of laminated composites containing multiple through-the-width delaminations

摘要: An analytical and experimental investigation was performed to study the compression response of laminated composites containing multiple delaminations. It particular interest determine effects delaminations on residual stiffness strength delaminated composite structures ability sustain compression. model developed for simulating re sponse, from initial loading final collapse, through-the-width The is comprised three parts: a stress analysis, failure contact analysis. analysis buckling post-buckling structures, pro posed predicting delamination growth fiber-matrix failure, analyzing interface condition during loading. A nonlinear finite element code based updated Lagran...
