“…160 HUByx was then used to recreate field cases involving less-lethal and lethal projectiles over an armour vest. 161 A methodology was proposed to predict rib fractures during kinetic energy projectiles impact, 162,163 and bone material properties were modified to predict fracture, with good agreement found with PMHS tests. 164 HUByx was also used to study blast loading 165 and penetrating ballistics.…”

“…However, since the HTFEM was not bio-fidelic, it cannot serve as a reliable reference for assessing the bio-fidelity of the HTM and Kang models. 154 , Awoukeng Goumtcha 157 , Goumtcha et al 158 , Bodo et al 159 , Bracq 160 , Bracq et al 161 , Bracq et al 163 , Chaufer et al 164 , Bodo and Roth 165 , Chaufer et al 166 Jaycor, 114 SSFEM, [135][136][137] and ATBM 34,[138][139][140] models were developed using an animal FE models to better understand injury mechanisms before building an accurate human FE model.

Human surrogates have long been employed to simulate human behaviour, beginning in the automotive industry and now widely used throughout the safety framework to estimate human injury during and after accidents and impacts. In the specific context of blunt ballistics, various methods have been developed to investigate wound injuries, including tissue simulants such as clays or gelatine ballistic, physical dummies and numerical models. However, all of these surrogate entities must be biofidelic, meaning they must accurately represent the biological properties of the human body. This paper provides an overview of physical and numerical surrogates developed specifically for blunt ballistic impacts, including their properties, use and applications. The focus is on their ability to accurately represent the human body in the context of blunt ballistic impact.

“…Once created, surrogates (either numerical or physical ones) were compared with experimental data to ensure their biofidelity. Some numerical models such as HUByx ( Roth et al, 2013 ; Bracq et al, 2019a ), SHTIM ( Nsiampa, 2011 ), or WALT ( Cronin et al, 2021 ) are consistent with biomechanical corridors and/or different field impact cases. To the authors’ knowledge, only a few physical surrogates in the open literature were consistent with ballistic biomechanical corridors, such as BTTR ( Bolduc and Anctil, 2010 ).…”

In the field of biomechanics, numerical procedures can be used to understand complex phenomena that cannot be analyzed with experimental setups. The use of experimental data from human cadavers can present ethical issues that can be avoided by utilizing biofidelic models. Biofidelic models have been shown to have far-reaching benefits, particularly in evaluating the effectiveness of protective devices such as body armors. For instance, numerical twins coupled with a biomechanical model can be used to assess the efficacy of protective devices against intense external forces. Similarly, the use of human body surrogates in experimental studies has allowed for biomechanical studies, as demonstrated by the development of crash test dummies that are commonly used in automotive testing. This study proposes using numerical procedures and simplifying the structure of an existing biofidelic FE model of the human thorax as a preliminary step in building a physical surrogate. A reverse engineering method was used to ensure the use of manufacturable materials, which resulted in a FE model called SurHUByx FEM (Surrogate HUByx Finite Element Model, with HUByx being the original thorax FE model developed previously). This new simplified model was validated against existing experimental data on cadavers in the context of ballistic impact. SurHUByx FEM, with its new material properties of manufacturable materials, demonstrated consistent behavior with the corresponding biomechanical corridors derived from these experiments. The validation process of this new simplified FE model yielded satisfactory results and is the first step towards the development of its physical twin using manufacturable materials.
