Hybrid Damage Prediction Procedure for Composite Laminates Submitted to Spectra Loading

Damage Assessment of Drilled Hybrid Composite Laminates

Hole drilling operations are common in fibre reinforced plastics FRP’s to facilitate fastener assembly to other parts in more complex structures. As these materials are non-homogeneous, drilling causes some damages, like delamination, for example. Delamination can be reduced by a careful selection of drilling parameters, drill material and drill bit geometry. In this work two types of laminates...

Inverse first-order reliability method for probabilistic fatigue life prediction of composite laminates under multiaxial loading Yibing Xiang and Yongming Liu* Department of Civil and Environmental Engineering Clarkson University Potsdam NY.13699, USA Abstract: Multiaxial fatigue reliability is a challenging problem despite extensive progress made during the past few decades. Anisotropic materi...

Peridynamic modeling of composite laminates under explosive loading

High velocity impact and shock or blast responses are a critical design characteristic determining sizing of composite parts and, ultimately, weight savings. This study demonstrates the applicability of peridynamics to accurately predict nonlinear transient deformation and damage behavior of composites under shock or blast types of loadings due to explosions. The peridynamic predictions correla...

Modelling 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...
