An analytical model to predict impact behaviour of soft armours

This paper presents a newly developed analytical model for predicting the impact behaviour of soft armours. It can be used to calculate the armour ballistic curve as well as the impact force, the tension in each layer, the displacement and velocity of the layers and projectile, the yarn stresses and strains and the damaged area. Fibres are assumed to be linear elastic up to fracture and the projectile perfectly rigid.
