HUByx is a finite element model of the human body simulating all the bones and organs as well as the internal fluid in between them, enabling the propagation of pressure wave inside the body.
HUByx is a first step in measuring the propagation of potentially lethal pressure waves inside the human body.
Validation of HUByx under an impact of 23.4 kg projectile at 6.5m/s as defined in Viano experiments.

CEDREM is a product performance enhancing company, working hand in hand with its customers. This ground breaking company is a team of multidisciplinary engineers and researchers specialized in complex systems analysis under dynamic loadings such as shocks, impacts, ballistics or explosions... Its dynamism and creativity in developing new numerical tools and new composite materials lead to a service at the cutting edge of innovation and new technologies to drive the shaping of new protection products.
Key Features & Benefits
The HUByx model is based on gathering CT scan slices of a 50th percentile man where all the visible organs have been outlined on the slices. Stacking these outlines created a volume for every organ and then organs volumes have been meshed within HyperMesh.
Several dynamic impacts have been simulated and the material laws of the body parts have been calibrated to reproduce the experimental results. Dynamic impacts vary in speed and projectile mass and geometries. For each case, a numerical curve has been compared to a validation corridor.
Another validation phase of the model has dealt with explosion tests. Merkle et al. has measured the pressure inside some organs of a torso surrogate under a specific experimental setting. This trial has been reproduced and the pressure curves have been measured inside the HUByx's organs. The numerical model has been considered validated for such loadings.

Ballistics: Instead of testing bullet-proof products on plastiline or rubber blocks, it is possible to simulate their behavior directly on the human body, see how pressure propagates after the impacts and study the difference of behavior depending on the location of the impact.
Explosion Protection: It is also possible to optimize blast protective equipment by simulating the effect of protections on pressure propagation inside the body.
Sports Industry: With HUByx, you can study the behavior of the human body under different kinds of sport impacts. For example, it is possible to simulate the protection of a football helmet, a biker’s back protection, a fencing face plate or a running shoe sole. Other examples include tennis racket optimization to reduce the force transmitted to the forearm bones and tendons.
Medical Industry: With HUByx, impact of medical activities on the human body behavior can be simulated.
