Another presentation that was held by @SM from the Politecnico di Milano  you during the EuroMed SIMULIA Conference 2024, on June 11-12, 2024, in Milan, Italy, and we are proud to share with you, is titled "Hybrid Anthropomorphic Test Device Model for Efficient Simulation of Crash Scenarios."

Abstract:

The work describes a numerical technique to represent aeronautical and pedestrian crash scenarios, aiming at investigating impact conditions that are then used to design efficient energy-absorbing structures and devices, thus enhancing the crashworthiness of vehicles.
Reconstruction of crash scenarios is based on mathematical modelling techniques, which can both provide quantitative results and cover multiple scenarios cost-effectively. A hybrid approach, i.e. the combination of Finite Element (FE) and Multibody (MB) techniques, has been adopted. A FE approach has been used to model those parts of the structure that need relevant details, addressing with an MB approach the remaining parts, typically the Anthropomorphic Test Device (ATD). Hybrid models have been developed using SIMULIA Abaqus/Explicit.
The aeronautical ATD is described and presented. It has been developed to model human injury during helicopter vertical impacts and used to design energy-absorbing structures, such as helicopter seats and subfloors. The ATD has been validated through three different experimental tests. Optimization of the model has been performed using SIMULIA Isight, allowing a better calibration of the contract laws. The same modelling technique has been adopted to develop the pedestrian ATD. It is used to model impacts between vehicle and Vulnerable Road User (VRU), and then to design the vehicle front-end, and its influence on the behaviour and damage occurring in the human body.
These two ATDs can be used to efficiently perform parametric studies of crash scenarios, and thus, this approach can usefully drive the design process.
