Mechanical analysis of helmeted headforms under ballistic impact with implications in performance evaluation of ballistic helmets

open access: yesFrontiers in Mechanical Engineering, 2023
Behind helmet blunt trauma is a significant health concern in modern warfare. The ballistic response of the human head under ballistic impact is highly sought. Towards this end, we conducted ballistic experiments on three different headforms.

Numerical investigation on effect of different projectile nose shapes on ballistic impact of additively manufactured AlSi10Mg alloy

open access: yesFrontiers in Materials
In the last few years, due to the superior mechanical qualities of Additive Manufacturing (AM) AlSi10Mg alloy to those of traditional casting process AlSi10Mg alloys, the application of AM technology has significantly increased.

Dynamic mechanical response and failure behaviour of AlMgB14-based ceramic: experimental observation, constitutive modelling and ballistic performance evaluation

open access: yesJournal of Materials Research and Technology
AlMgB14-based ceramics have emerged as promising materials for ballistic protection due to their ultra-hardness and low density. However, their dynamic mechanical behaviour and ballistic performance remain underexplored.

Effect of Periphery Fixity on Ballistic Limit of Thin Aluminum Plate Subjected to Blunt and Ogival Projectile Impact

open access: yesInternational Journal of Applied Mechanics and Engineering, 2014
Three-dimensional numerical simulations were carried out with the ABAQUS/explicit finite element code to study the influence of target boundary conditions on its ballistic limit. 1mm thick 1100-H12 aluminum target of 255 mm span diameter was hit by 19 mm

Simplified simulation of impact bullet - stratified pack for restraining ballistic tests [PDF]

open access: yesMATEC Web of Conferences, 2017
This paper presents a macro FEM isothermal model for simulating the impact of a 9 mm FMJ bullet on a stratified packs in order to restrain the preliminary tests for actual stratified packs made of layers of Twaron LFT SB1plus (Teijin), taking into account the friction between layers and between bullet and layers, in order to obtain the number of layers

Ballistic Performance Evaluation of Aluminium Plate Impact by Fragment Simulating Projectile

open access: yesJournal of Physics: Conference Series, 2020
Abstract The ballistic performance has drawn attention to researchers from a military background. They intend to provide solutions to ensure the soldiers in the front line of war do not kill in action. A casualty in war can lead to depression among soldiers and not to mention to their family as well.

Evaluation of UHMWPE prepreg laminates under near simultaneous multiple projectile impacts: Effects of structural shapes and projectile dispersions

open access: yesDefence Technology
Multiple projectile impacts are significant threats in real-world military and anti-terrorism operations. Previous researches have mainly focused on the protection mechanism and structure design against a single projectile impact.
