“…The latest trend is to draw risk curves where a distribution is used to describe injury tolerance limit. [39][40][41][42] These curves express conditional probability, since they show that how large the injury probability is if the characteristics of the effect (which can be either an input or an output variable) has a specific intensity.…”

Traumatic brain injuries (TBIs) contribute to a high degree of mortality and morbidity in society. From engineering point of view, the human brain can be considered as a mechanical system which is subjected to extreme effects, since every type of TBIs are derived from the large magnitude of mechanical loads. Impact biomechanics deals with the prevention of injuries via the suitable design of safety systems. It requires the quantification of limit values of the mechanical effects that humans can tolerate. The goal of this paper is twofold. Firstly, it contains a brief literature review where some of the most important milestones and major conclusions of previous researches are mentioned. Secondly, it presents a proposal about the applicability of reliability analysis to assess the vulnerability of the human brain.

“…However, the human body's ability to withstand such acceleration is limited, and exceeding these limits can result in severe injury or even death. Therefore, understanding the extent to which humans can tolerate such acceleration is essential in determining the necessary safety features and structural elements required to protect occupants in foreseeable crashes [35][36][37][38][39]. By knowing the crash environment and the limits of human tolerance to acceleration, designers can set crashworthiness design requirements that will effectively safeguard passengers in a variety of collision scenarios.…”

The bumper beam is a crucial component of the automobile bumper system, responsible for absorbing impact energy and enhancing the safety of passengers during collisions. This paper presents the design and experimental analysis of a 3D-printed composite–plastic hybrid light structure, designed as a collapsible energy absorber. Exploratory testing was conducted using low-impact tests to investigate the failure mechanism and energy absorption capacity of a spiral structure. The design process involved optimizing the spiral diameter by testing specimens with varying diameters between 0.5 cm and 2.5 cm, while keeping other geometric parameters constant. The study employed three types of 3D composite structures, including printed thermoplastic, printed thermoplastic reinforced with Kevlar fiber composite, and printed thermoplastic filled with foam. The thermoplastic–foam composite with nine spirals (diameter = 0.97 cm) yielded the best results. The new design demonstrated high energy absorption capacity and a controlled and progressive failure mechanism, making it a suitable candidate for energy absorption applications.
