“…On the component level of validation, a.k.a. sub-model validation [77], responses of individual body segments are studied under static, quasi-static and dynamic loads. Reference data is mostly obtained from PMHS tests using impactors of different sizes (rectangular, cylindrical, spherical), masses (e.g.…”

“…For optimisation, many safety analysis or forensic software packages are equipped with their own optimisation modules [22,33,168]. External commercial packages are also used for optimisation in pedestrian simulations [62,143,200], with MATLAB being a notable example [76,77,142,211].…”

The review paper discusses numerical human body models of pedestrians. The background of current trends in physical and mathematical pedestrian research is presented. Development, validation and areas of application of pedestrian body models are described. The differences between multibody models and finite element models are presented. Accident-based and experimental approaches to validation of the models are discussed. As a novelty, this paper presents an overview of multibody models used in forensic investigations, discusses their usefulness, and differences between their design and the design of more advanced multibody and finite element models. Finally, the most recent trends in human body modelling are discussed, including open-source approaches to model distribution and replacement of physical tests by digital simulations.

The finite element method is the most common method used to solve engineering and mathematical model problems. Related solution areas include structural analysis, heat transfer, mass transport and electromagnetic potential. FEM is a specific numerical method used to solve partial differential equations in two or three space variables. To solve a problem, FEM breaks up a large system into smaller, simpler parts called finite elements. First, a three-dimensional model of the system to be analyzed is produced. While defining the model, the materials and connection types found in the model are also deter-mined. Afterwards, the model is divided into small parts and analyzed under specified conditions. A crash test will be conducted in this study. For this, the conditions of the vehicle parts will be examined by hitting a wall under the conditions of which the model design of the vehicle is determined. Crash tests were carried out for two different bumper thicknesses on the same vehicle and the test results were examined. The vehicle speed is modeled as 20 m/s in the simulation carried out from the moment of impact until 0.14 seconds later. The effect of buffer thickness on axial displacements at impact and energy changes are presented.
