WS8D-3 NAS120, Workshop 8D, May 2006 Copyright 2005 MSC.Software Corporation l Workshop Objectives: l Practice performing an analysis of composite materials. l Problem Description: l Create your own composite layup for the tension coupon. l The composite plies are graphite/epoxy tape with a thickness of in. l The elastic and strength properties are shown on the right. l The failure theorem to be used is Hill. l Use enough plies to build up a total thickness of l Define the 0 degree material direction in the basic coordinate system x-direction.
WS8D-4 NAS120, Workshop 8D, May 2006 Copyright 2005 MSC.Software Corporation l Suggested Exercise Steps 1. Open any of the previous tension coupon workshops. 2. Define the ply material properties 3. Define composite material properties 4. Create a new laminate shell property to replace the existing homogenous shell property. Define material orientation per problem description on the previous page. 5. Submit the model to MSC.Nastran for analysis. 6. Post Process ply results using MSC.Patran.
