Specialty Virtual Human Models
Expand virtual testing beyond conventional models with greater flexibility across diverse populations, anatomies, postures, and applications.
GHBMC specialty models broaden the scope of virtual human body modeling to address simulation requirements not covered by standard occupant and pedestrian representations. The available models include Aged, Regional, ATD-Analogous, and Chinese GHBMC, each supporting better-informed design decisions through tailored models that reflect specific human characteristics and evaluation objectives.
Aged Models
The Aged models include three derivative models based on the Detailed 50th percentile male occupant model (M50-O) and the Detailed 50th percentile female occupant model F05-O. The models represent target ages of 24, 42, and 70 years and are designed to complement the baseline models. For more details, see publications.
Model Development
Model morphing
M50 and F05 models were morphed to match anatomical characteristics corresponding to the target ages
Geometry adjustments
Model geometry was adjusted through element reassignment
Material modification
Material properties were modified to reflect physiological changes associated with aging
ATD-Analogous Models
ATD-Analogous models are designed for use in crash simulations, including frontal impact tests and regulatory crashworthiness assessments. These models correspond to physical anthropomorphic test devices (ATDs), enabling virtual evaluations that complement established crash-testing methods. For more details, see the referenced publication.
Key Capabilities
Direct comparison
Enable direct comparisons between human body models and ATDs
Expanded test scenarios
Support evaluation of conditions that physical test devices cannot easily replicate, including low-speed maneuvers and oblique impacts
Matched simulations
Provide an analogous human response when paired with ATD counterparts in matched simulations
Regional Models
Regional models provide focused representations of specific anatomical areas for targeted simulation and analysis. Custom regions are also available for additional modeling needs and can be requested through Elemance Support.
Regions Available
Head
The isolated head model (M50-H) is available in two versions:
(1) Fully Deformable Skull – Supports evaluation of skull and facial fractures and their associated effects on brain tissue
(2) Rigidized Skull – Supports simulations in which skull deformation is not expected, including helmeted impact scenarios
Brain
The M50-Brain model enables detailed analysis of brain deformation during real-world impacts without compromising skull integrity. Ideal for helmeted sports and similar scenarios, it provides researchers and product developers with precise insight into brain response.
Thorax
The Isolated Thorax model enables simulation of chest impacts and assessment of resulting injuries, including rib fractures, to support the development of safer products and protective systems.
Head and Neck
The Head and Neck model preserves the kinetic chain between the head and torso to capture force and energy transfer during movement and impact. It also supports direct comparison with head/neck dummy rigs, including the Hybrid III Head + Neck, to evaluate neck motion and loading.
Chinese GHBMC
The M50-O Chinese Human Body Model was built to represent a variant of the Chinese population. Using the Chinese national standard for population anthropometry, this model reflects the 50th percentile male of Chinese populations.
Key Characteristics
Flexible model fidelity
Available as both Simplified and Detailed occupant models to accommodate different simulation requirements and levels of anatomical detail
Anthropometric accuracy
Both models are morphed to Chinese anthropometry based on the national standard (GB/T 10000-2023, Human Dimensions of Chinese Adults), with measurements maintained within ±5% of Chinese 50th percentile male targets and flesh-part densities scaled within physiological ranges to match target mass
Simulation robustness
Tested in highly automated vehicle (HAV) robustness cases and Human Body Models for Virtual Testing (HBM4VT) boundary conditions to assess performance across established simulation conditions
Reclined Models
As vehicle designs evolve to incorporate a wider range of occupant postures, reclined-position modeling is becoming increasingly important for realistic safety simulation. Request model information.
Key Characteristics
Multiple recline angles
Available at 45-degree and 60-degree seat back angles to represent a range of reclined occupant positions
Detailed and simplified models
Available as both M50-O (detailed 50th percentile male occupant) and M50-OS (simplified 50th percentile male occupant) to support different simulation requirements and levels of anatomical detail
Validated positioning
Reclined postures were developed using joint-angle targets from the posture prediction equations in Reed et al (2019), with both models matching target angles within one (1) degree.
