• Editorial: 'FABIG is planning a 2-day Technical Meeting in March 2022'
  G. Vannier - FABIG Project Manager
• Fire risk of transporting and storing massive Li-ion batteries
  Y. Liu and X. Huang - The Hong Kong Polytechnic University
  This paper investigates the self-heating ignition characteristics of cylindrical battery piles and determines the thermal-runaway criteria. The thermal runaway phenomena, effective kinetic parameters of self-heating reactions and thermal properties are discussed and analysed. The self-ignition limit of larger-scale battery piles in storage and transport is predicted via extrapolation of results of hot-oven experiments.
• Automated design for corrugated blast wall projects - On weight savings and a partitioning method for larger numbers of design cases
  N. Riemens and R. Dedden - InterDam
  This paper presents a comprehensive strategy for the design of corrugated blast walls for large projects where the number of distinct design cases makes it challenging to achieve economic design via manual methods. An automated partitioning method is used to partition design cases into a small number of groups, each having a distinct blast wall design. This allows the right balance to be struck between material cost savings and project complexity, and leads to a significant reduction in total project cost.
• Optical diagnostics in near field blast measurements

  This article demonstrates the usefulness of improved diagnostics and techniques in blast experiments and shows the efficacy and versatility of high-speed imaging and digital image correlation for determining impulse profiles and transient structural behaviour. Ultra-high speed imaging is also shown to be a useful tool for visualising detonation fronts in explosive charges and the expanding fireball.
