A novel hybrid prediction approach for critical buckling strain of dented subsea pipelines coupling symbol regression and physics-informed neural networks

This study proposes a novel hybrid approach to predict the critical buckling strain (CBS) of dented subsea pipelines by coupling symbolic regression (SR) with physics-informed neural networks (PINNs). A 3D finite element model was developed to simulate pressurization, indentation...

Numerical Investigation of LPG Leakage Dispersion and Explosion Consequences in a Spherical Tank with Safety Walls

Abstract Liquefied petroleum gas (LPG) leakage from spherical tanks can generate near-ground flammable vapor clouds and subsequent fire and explosion hazards. A three-dimensional FLACS model of a 1000 m3 LPG spherical tank was established to investigate the effects of safety-wall...
