Application of a Global/Local Finite Element Model to Composite Laminates

A global/local finite element model is used to analyze composite laminates with local effects such as a hole and a free edge.In this simultaneous model, the domain of the structure to be analyzed is divided into three areas: local region, global region, and transition region.A degenerated plate/shell element with assumed partial stress field is used to model the overall response of the laminated composite in the global region, a 3-D solid element is used to predict detail stress distribution in the local region, and a transition element is used to connect two different elements smoothly.In the global/local model, all of the elements are derived from the combined energy variational principle.So it is a self-consistent finite element model.In addition, the global/local finite element model satisfies the continuity of interlaminar stresses at the interlayer surface and traction condition on the top and bottom surface of laminated composites.In order to show the efficiency and accuracy of the global/local model for stress analysis of laminated composites, a laminated strip with free edge and a square laminate with a hole are investigated.Vol. 5, Nos.3-4, 1996 Application of a Global/Local Finite Element Model to Composite Laminates
