Abstract
This paper deals with a problem of validation of parameters of the most popular equation of state describing the function of pressure during explosion - JWL (Jones – Wilkins – Lee). For this purpose, the cylindrical test was conducted experimentally and was modelled using three different methods: arbitrary Lagrangian -Eulerian (ALE), smoothed particle hydrodynamics (SPH) and pure Eulerian approach. The cylindrical test was simulated using three methods mentioned above with 2D axisymmetric model and quarter of 3D model. Finally, different types of elements for the discrete models of copper pipe were investigated. The comparison of the outcomes from experiment and numerical simulations showed acceptable similarity.
