摘要: A novel ply drop-off element has been developed for the analysis of tapered laminated composites. The capability to accommodate within element. Therefore, need not lie along nodal lines. As a result, location is independent mesh division. This facilitates use coarse at drop even when stagger distance very small. can be used in global model without increasing size structural matrices. stiffness matrix by superimposing matrices all layers. Since dropped layer different from special integration technique adopted developing In addition, degenerated 1D discussed. lateral dimension plate high comparison longitudinal dimension. validation proposed carried out with help numerical examples.
