Applications

Protecting human life comes in many shapes and sizes. Take a peek inside some of the industries we serve and learn about how the GHBMC family of models can protect life and help prevent injuries through virtual simulation.

Automotive

The GHBMC models were originally designed with funding from the automotive industry, so they are a perfect fit for evaluating automotive passive safety systems for occupants and active safety systems for pedestrians.

Sports

The GHBMC models can be integrated with protective sports gear like helmets and shin guards to simulate real world injuries and help improve upon current protection measures for players.

Play Smart. Play Safe.

The NFL and Wake Forest University develop open-source finite element (FE) models of four football helmets.

Case study

The team at Wake Forest University and Elemance developed a finite element model of one population football helmet, the Schutt Air XP Pro model.

As part of the NFL’s Play Smart. Play Safe. initiative, the NFL pledged $60 million toward the understanding of the biomechanics of head injuries in professional football and to create incentives for helmet manufacturers, small businesses, entrepreneurs, universities and others to develop and commercialize new and improved protective equipment, including helmets.

The work was done through a process of “reverse engineering” the helmet; from image-based geometry development, to extensive material characterization, and finally model validation to ensure the simulated impacts match real-world experiments. The helmet model was fit onto various head forms and simulated through a series of nearly 70 matched simulation-to-experimental tests, which included impacts of similar severity as those that occur on the field. These virtual helmet models give researchers an additional tool to study the relationship between various in-game modes of impact and the associated risk of head injury.

Aerospace

A study was performed to understand the extent to which 50th percentile male anthropomorphic test devices (ATDs) predict injury risks in spaceflight-like loading conditions.

Case study

Between 1976 and 2013, a combination of Hybrid III, THOR, and human volunteer tests were conducted using both the Horizontal Impulse Accelerator (HIA) and Vertical Deceleration Tower (VDT) at Wright-Patterson Air Force Base and USAF Armstrong.

These tests formed a matrix for finite element (FE) validation.  Simulations were performed using the Global Human Body Models Consortium (GHBMC) 50th male simplified occupant (M50-OS), Humanetics 50th percentile male Hybrid III, and NHTSA THOR 50th male FE models in LS-DYNA.

Disc replacement integrity

Elemance evaluates the performance of a C5-6 disc replacement during an aircraft impact.

Case study

A computational finite element analysis was performed to evaluate the effects of C5-6 cervical total disc replacement (CTDR) on cross-sectional neck loading and cervical spine kinematics during a simulated rotary-wing aircraft ground impact.

The neck of a human body finite element model was modified to include a C5-6 interbody arthroplasty with either a Prestige ST or ProDisc-C CTDR. The adjacent-level, cross-sectional loading for the C5-6 segment was not greatly altered by the CTDRs, as indicated by CORrelation and Analysis (CORA) ratings of 0.988 for the Prestige ST and 0.909 for the ProDisc-C. The CTDRs increased the interbody range of motion, altering both the interbody and cervical facet loading. While the facet capsules experienced increased tension in both CTDR simulations, established injury threshold levels were not reached. Overall, cervical arthroplasty at the C5-6 level did not appear to have a deleterious effect on the dynamic neck response during a simulated rotary-wing aircraft impact.

Military

Under body Blast (UBB) events are the cause of many serious injuries sustained by soldiers in combat zones to the pelvis, spine, and lower extremities.

Case study

Military operations in Iraq and Afghanistan over the past several years have resulted in the increased exposure of military personnel to improvised explosive devices (IEDs) and road side bombs.

Injuries caused by under body blasts are often debilitating, resulting in increased healthcare expenses and a reduced quality of life. Injury prediction for UBB events continues to be a challenge due to the limited availability of UBB‐specific test studies and injury criteria. This study focused on the pelvic injury response of the 50th percentile male (M50-O) Global Human Body Models Consortium (GHBMC) Finite Element model.
