FE dummy models are virtual representations of their respective physical crash test dummy. The FE dummy models are created to simulate the behavior of a crash dummy in motor-vehicle and pedestrian collisions, as well as for aircraft, railcoach and military applications. The goal is to record as much data as possible for the dummy responses such as accelerations, forces, and displacements during an impact collision to determine the injury risks. The predictive capabilities of finite element analysis (FEA) allow engineers to fully analyse a crash event in a virtual environment. This potentially saves significant costs by better understanding vehicle and restraint performance upfront, thereby reducing the number of physical tests to be executed.
Humanetics is the world's leading supplier in the design and manufacture of sophisticated crash test dummies, associated test equipment and laboratory services, development of Finite Element (FE) software dummy models for virtual crash test simulations, and specializes in development, manufacture, and integration of a comprehensive array of sensors and Data Acquisition Systems (DAS). Humanetics has been dedicated to continuous growth in occupant safety testing and measurement for the advancement of safer vehicles for over 65 years and will continue to do so through outstanding customer focus and innovative designs to ultimately make the world safer by saving lives.
“Humanetics FE dummy models have become the global standard. Our accuracy, robustness and user-friendly experience is key to the development process. We are excited to extend our relationship with Altair by offering FE Dummy Models by Humanetics to its wide range of industrial customers currently using Altair Radioss.”
President and CEO of Humanetics.
Key Features & Benefits
- FE dummy models are virtual representations of physical dummies.
- Allows for a crash event to be simulated on a computer instead of doing physical dummy testing
- Enables virtual design iterations saving development and certification costs

FE Dummy Models are primarily used in Aerospace, Automotive, Consumer Goods, Pedestrian and Defense. Some industrial examples include:
Aerospace and Military dummies cover a range of applications: civilian aircraft testing, fixed wing and rotary; military parachutes; aircraft with crew ejection seat systems; and ballistic impact counter-measures. They are tools for the equipment developer to use to ensure the safe, effective use of their applicable products.
Automotive dummies include: front-impact, side-impact, rear impact and children dummy models. Testing with these dummies expanded the capabilities of the test engineer to help design vehicles to protect the occupants.
Pedestrian dummies have been crucially important in the development of today’s modern motor vehicle. Tests with these dummies have helped to dictate the frontal shape of the vehicle so that the effects of car-pedestrian impacts are mitigated to prevent injury and death.
FE Dummy Models integrate with Altair RADIOSS.
Leading structural analysis solver for highly non-linear problems under dynamic loadings like Crash, Impact, Blast and Stamping simulation.
