“…For the ith ribbon layer, if s i is denoted as the stress in the length direction of this ribbon layer, the circumferential stress is s i cos 2 q [14], and thus, the equation of motion for the ith ribbon layer is Because the materials of the inner shell and outer ribbon layers are strain-rate sensitive, s and s i can be expressed by…”

Explosion containment vessels (ECVs) are used to fully contain the effects of explosion events. A discrete multi-layered cylindrical shell (DMC) consisting of a thin inner cylindrical shell and helically cross-winding flat steel ribbons has been proposed, which has obvious advantages of fabrication convenience and low costs. The applications of ECVs are closely associated with blast and thermal loads, and thus, it is important to understand the response of a DMC under transient thermal load in order to develop a design code and operation procedures for the use of DMC as ECV. In this paper, a mathematical model for the elastic response of a DMC subjected to thermal loading due to rapid heating is proposed. Based on the axisymmetric plane strain assumption, the displacement solution of the dynamic equilibrium equations of both inner shell and outer ribbon layer are decomposed into two parts, i.e. a thermo-elastic part satisfying inhomogeneous stress boundary conditions and a dynamic part for homogeneous stress boundary conditions. The thermo-elastic part is solved by a linear method and the dynamic part is determined by means of finite Hankel transform and Laplace transform. The thermo-elastic solution of a DMC is compared with the solution of a monobloc cylindrical shell, and numerical results are presented and discussed in terms of winding angle and material parameters.

Three discrete multilayered vessels with the same materials and dimensions except for steel ribbon winding angles were fabricated and tested to investigate their dynamic response and fracture characteristics subjected to internal blast loading induced by TNT set at the centers of their cavities. All the vessels were damaged at the cylindrical portion around the explosion center. The results indicate that the vessel with a smaller ribbon winding angle has a better ability to withstand internal explosion and that there are mainly tensile strains along the steel ribbons and compressive strains across the steel ribbons.
