We are pleased to inform you that the 86^th edition of the FABIG Newsletter is now available on the FABIG website.

FABIG Members are able to download Issue 086 from the Technical Newsletters section of the website (once logged-in) whilst non-Members of FABIG are able to purchase it.

This issue comprises the following:

• Editorial
  G. Vannier - The Steel Construction Institute (SCI)
• Modelling blast wave clearing using Load_Blast_Clearing: Part 2 - Oblique clearing and TNT equivalence
  L. Schwer¹, S. Rigby² and T. Slavik³ - ¹Schwer Engineering & Consulting Services, ²University of Sheffield, ³Ansys, Inc.
  This paper follows the verification and validation study of the new LS-DYNA keyword Load_Blast_Clearing (LBC) published in Newsletter Issue 85. This new keyword modifies the “standard” Load_Blast_Enhanced (LBE) predictions to account for pressure reduction due to blast wave clearing. The objective of this paper is to validate the new keyword Load_Blast_Clearing against experimental results involving oblique Mach Stem reflections. A method for estimating the TNT equivalence for Mach Stem reflections is presented for this purpose.
• The challenges of transitioning to Fluorine Free Foam in a major energy company
  E. Paillier and P. Hoorelbeke - TotalEnergies
  This paper discusses the challenges posed by the transition from Aqueous Film Forming Foams (AFFF) to Fluorine Free Foams (FFF) for fire-fighting as legislation to protect the environment and people’s health via a ban of the PFAS family of chemicals is evolving fast in Europe and other countries worldwide.
• Simulation of a premixed explosion of gas vented during Li-ion battery failure
  M. Henriksen¹, K. Vaagsaether¹, J. Lundberg¹, S. Forseth² and D. Bjerketvedt¹ - ¹University of South-Eastern Norway, ²Norwegian Defence Research Establishment (FFI)
  This paper presents a Computational Fluid Dynamics (CFD) method for simulating explosions of gases vented from failing LIBs using open-source software. The code mech2Foam was used to generate the required CFD input parameters for Li-ion battery vent gas composition, which was then used in several CFD simulations of explosions in a 1-meter rectangular channel. The simulation results were compared with experimental results for validation of the method and the CFD model.

Take care and stay safe,
