Plasticity Methods in Protection and Safety of Industrial Plant and Structural Systems Against Extreme Dynamic Loading

Abstract

This paper provides an overview of the contributions that plastic methods of analysis can make to the protection of the public and the security of industrial plant against extreme dynamic loading events which involve explosive blast pressures or impact loadings from various projectiles. It is possible, by careful design, to absorb the external dynamic energies through large inelastic deformations of the structural members and specially designed energy-absorbing systems. Both the protection methods are examined briefly, together with some discussion on the dynamic properties of materials, including inelastic failure, and the impact perforation of ductile metal structures. Some phenomena are emphasised that are important for numerical finite-element schemes as well as theoretical methods of analysis.

Probabilistic performance analysis of structural elements subjected to blast load using equivalent static force model

“…Pressure impulse curves (or iso-damage curves) were also proposed using a single degree of freedom approximation to aid the design of structural elements subjected to blast (Fallah and Louca, 2007;El-Dakhakhni et al, 2009;Dragos and Wu, 2014;Xu et al, 2014). Detailed finite element analysis using various FEM software such as Abaqus, Ansys, and LS-DYNA were used to simulate blast load and observe the corresponding dynamic response of structure (Jones, 2008;Jayasooriya, 2010;Biju and Ramesh, 2017).…”
