Abstract
Brain injury resulting from improved explosives devices (IEDs) is identified as a challenge for force securities to improve protection equipment. This paper focuses on the mechanical response of explosive ordnance disposal (EOD) helmet under different blast loadings. Limited published studies on this type of helmet are available in the scientific literature. The results obtained show the blast performance of the EOD helmet because a decrease in the maximum values in the measured damage parameters is found. Therefore, an EOD helmet minimizes the risks of the severity of injuries on the user showing a low probability of injury.
Highlights
Nowadays, due to armed conflicts and terrorist threats, people injured and killed by explosive devices as weapons represent a significant percentage worldwide
First personal protection equipment appeared in the First World War and has evolved to the modern suits worn by the explosive deactivation technicians or explosive ordnance disposal (EOD) suits
They concluded that the presence of additional protective equipment reduces maximum pressures in the brain (ICP) by up to 5 times, and this guarantees that no skull fracture occurs
Summary
Due to armed conflicts and terrorist threats, people injured and killed by explosive devices as weapons represent a significant percentage worldwide. Rodriguez Millan et al [10] used a Finite Element Method (FEM) model in the ABAQUS software to analyze the effect of a fully covered ACH helmet, that is, a visor and a jaw guard have been added as complements to improve its effectiveness They concluded that the presence of additional protective equipment reduces maximum pressures in the brain (ICP) by up to 5 times, and this guarantees that no skull fracture occurs. Tan et al [15] have developed a virtual model of finite elements of a human head and a helmet in order to help in the design of the generations of helmets for ballistic and explosion protection. Li et al (2020) carried out an experimental and numerical study to obtain the overpressure on the head in different blast wave directions They used an ACH helmet without complements to protect the face. (iv) A limit for the use of the helmet has been defined based on the widely accepted criterion of HIC and has been directly related to the severity of injuries produced
