Crash
test dummies, knows as Anthropomorphic test Devices (ATD) are life size
models measuring injuries a human would experience in an impact or
injury situation.
Four years ago LSTC decided to begin developing finite element models of dummies and barriers. As part of this development, LSTC employed state-of-the-art capabilities, which are unique to LS-DYNA, including meshless solid and shell elements to improve robustness, smooth contact to model joints, and advanced constitutive models to model the complex behavior of hyperelastic materials including aging.
This work is now well underway, and its current success can be attributed not only to the work of the National Crash Analysis Center (NCAC), DYNAmore GmbH, and the dedicated LSTC engineers, but to several automotive suppliers and OEMs who have been critical in supplying surface data, test and validation data and feedback related to the performance of their models.
LSTC is still in the early stages of their dummy developments, and much effort is required before their ultimate goals are achieved.
They have committed to funding NCAC to accelerate these developments. DYNAmore GmbH in Germany joined LSTC and committed their efforts to the development and validation of the EuroSID dummies.
