The purpose of this paper is to investigate the applicability of the LS-DYNA software using a Lagrangian formulation in the jet formation, flight and penetration of improvised explosively formed projectiles (EFPs). Numerical results dealing with different properties of the EFPs have been validated with a significant number of field tests.

2D and 3D Lagrangian models, using different material definition, are developed to reproduce the field-measured characteristics of copper- and steel-made EFPs: projectile size and velocity. After validation, the model has been extended to analyse the penetration features. Two different plasticity models have been used to describe the steel target, Plastic-Kinematic and Johnson–Cook.

Despite the difficulty in characterizing a non-industrial artefact, the results show that both Lagrangian models (2D and 3D) are able to simulate the projectile size, velocity and penetration capability with errors less than 10 per cent when using the Johnson–Cook material model for both liner and target.

These data can be used to test the penetration ability of improvised EFP’s against different targets, i.e. light armoured vehicles.

There are no references that address the application of the Lagrangian simulation of non-industrial EFPs and its validation with field tests, including penetration assessment.

This paper traces the evolution of (Catholic) church‐state relations from Nicaraguan independence through to 1998, showing how a symbiotic relationship has emerged whereby one makes recourse to the other in order to justify its existence and provide it with moral authority. This relationship, however, has been threatened on a number of occasions. First, by the advent of liberation theology during the Somoza period, second by the increasing secularisation of the FSLN regime during the 1980s. Recent years have seen the Catholic Church recapture its previous authoritative position in the national political arena, although increasing voter apathy and the growth of the Protestant Church movement could again threaten its position.

Examines the tenth published year of the ITCRR. Runs the whole gamut of textile innovation, research and testing, some of which investigates hitherto untouched aspects. Subjects discussed include cotton fabric processing, asbestos substitutes, textile adjuncts to cardiovascular surgery, wet textile processes, hand evaluation, nanotechnology, thermoplastic composites, robotic ironing, protective clothing (agricultural and industrial), ecological aspects of fibre properties – to name but a few! There would appear to be no limit to the future potential for textile applications.
