Delamination threshold load for dynamic impact on plates
A criterion is derived for delamination onset in transversely isotropic laminated plates under small mass, high velocity impact. The resulting delamination threshold load is about 21% higher than theExpand

Predicting low velocity impact damage and Compression-After-Impact (CAI) behaviour of composite laminates
Low-velocity impact damage can drastically reduce the residual strength of a composite structure even when the damage is barely visible. The ability to computationally predict the extent of damageExpand

Structural testing and numerical simulation of a 34 m composite wind turbine blade
A full-scale 34 m composite wind turbine blade was tested to failure under flap-wise loading. Local displacement measurement equipment was developed and displacements were recorded throughout theExpand

A progressive failure model for composite laminates subjected to low velocity impact damage
This paper presents a 3-D failure model for predicting the dynamic material response of composite laminates under impact loading. The formulation is based on the Continuum Damage Mechanics (CDM)Expand

An investigation of Mode I and Mode II fracture toughness enhancement using aligned carbon nanotubes forests at the crack interface
Abstract A novel approach for introducing aligned multi-walled carbon nanotubes (MWCNTs) in a carbon–fibre composite pre-impregnated (prepreg) laminate, to improve the through-thickness fractureExpand

Postbuckling behaviour of a blade-stiffened composite panel loaded in uniaxial compression
Abstract The postbuckling behaviour of a panel with blade-stiffeners incorporating tapered flanges was experimentally investigated. A new failure mechanism was identified for this particular type ofExpand

A 3-D micromechanical model for predicting the elastic behaviour of woven laminates
Abstract This paper presents an analytical model for the prediction of the elastic behaviour of plain-weave fabric composites. The fabric is a hybrid plain-weave with different materials andExpand
