The use of low frequency (less than 10 kHz) guided waves for structural health monitoring (SHM) against third party intrusion into long pipelines is investigated. A guided wave (GW) is sent along a...

Ship collision analysis outcomes are generally used in computational models to derive damage distributions. However, damage is usually assessed after the collision energy has been fully absorbed by structural members rather than at the onset of outer

This paper presents the probabilistic characterisation of basic variables of ship structures and their application in characterising ship hull response during collisions. 83 dog-bone samples from mild steel are tested until fracture by axial displace

Cellular materials have applications for impact and blast protection. Under impact/impulsive loading the response of the cellular solid can be controlled by compaction (or shock, see Tan et al. (2005) [3] , [4] ) waves. Different analytical and compu

Elementary one-dimensional wave theory is often used to describe the propagation of longitudinal stress waves in polymer rods. More accurate solutions are available, but they are mathematically difficult. A new wave equation is derived for long polym

The in-plane dynamic crushing of 2D hexagonal-cell honeycombs has been simulated using finite elements to explore the dynamic response of cellular materials and to investigate the features of the crushing front and to examine the assumptions employed

Orthopaedic rehabilitation of osteoporosis by muscle vibration exercise is investigated theoretically using Wolff's theory of strain-induced bone ‘remodelling’. The remodelling equation for finite amplitude vibration to be transmitted to the bone

One means of protecting structures involves the panelling of components with foam. Previous work has analysed the response of a low-density aluminium foam to quasi-static, and low velocity impact. In the present work, plate impact experiments are con

The development of an analytical model based on a ‘bar–hinge’ idealisation is described. It is used to investigate the structural response of a one-dimensional chain of components each constructed from a pair of slightly bent elastic–plastic

One-dimensional ‘steady-shock’ models based on a rate-independent, rigid, perfectly-plastic, locking (r-p-p-l) idealisation of the quasi-static stress–strain curves for aluminium foams are proposed for two different impact scenarios to provide
