Low Velocity Impact Damage Prediction in Laminated Composite Plates
In this paper, a finite element model is presented for the transient analysis of low velocity impact, and the impact induced damage in the composite plate subjected to low velocity impact is studied. The failure criteria suggested by Choi and Chang and the Tsai-Hill failure criteria are used for the prediction of the damage in the composite plate; then the effect of various parameters on the im...
متن کاملDrilling Damage in Composite Material
The characteristics of carbon fibre reinforced laminates have widened their use from aerospace to domestic appliances, and new possibilities for their usage emerge almost daily. In many of the possible applications, the laminates need to be drilled for assembly purposes. It is known that a drilling process that reduces the drill thrust force can decrease the risk of delamination. In this work, ...
متن کاملModelling low velocity impact induced damage in composite laminates
The paper presents recent progress on modelling low velocity impact induced damage in fibre reinforced composite laminates. It is important to understand the mechanisms of barely visible impact damage (BVID) and how it affects structural performance. To reduce labour intensive testing, the development of finite element (FE) techniques for simulating impact damage becomes essential and recent ef...
متن کاملRemote inspection system for impact damage in large composite structure
A significant opportunity for reducing the weight of composite aircraft is through the development of an economically-efficient method to detect barely-visible or invisible impact damage sustained in service. In this paper, a structurally-integrated, inert, wireless system for rapid, large-area impact damage detection in composite is demonstrated. Large-area inspection from single sensors using...
متن کاملMaterial trades and structural analysis of a composite structure
In order to design a composite system specific for a particular mission, it is necessary to perform a materials trade study and structural analysis first. Through the use of software such as: Analam, 6strut, and Strut Design Tool the best material makeup can be identified. Then, by using Patran, MSC Nastran and Sigmax a finite element model based on a real structure can be set up and used to fi...
