Response of profiled barriers subject to hydrocarbon explosions

摘要: This paper presents a numerical methodology to investigate the response of stainless steel profiled barriers when subjected blast loading generated from hydrocarbon explosion. Results three large-scale explosion tests are used validate Abaqus/Explicit finite-element code adopted in analyses. A simple failure algorithm based on equivalent plastic strain has been implemented model ductile weld tearing behaviour. The effects rates, sensitivity mesh densities and load idealisation will be discussed. brief review deep trough corrugated blastwalls that exhibit very different behaviour also presented. concludes with some parametric studies characteristics determine capacity blastwall.
