Experiment¶

Information on the subjects/specimens¶

3 female specimen (average age: 56 yrs, average mass: 57.8 kg, average height: 161.8 kg)
11 male specimen (average age: 53.2 yrs, average mass: 70.25 kg, average height: 173.4 cm)

Loading and Boundary Conditions¶

Low-Speed (LS), Medium-Speed (MS) and High-Speed (HS) Impacts at the area of the hip, upper abdomen and thorax.

Impact¶

Impact Location	Midpoint of Impactor aligned with	Impact angle	LS	MS	HS
Thoracic Impact	Xiphoid process (XP)	330°	4.4	6.5	-
Abdmoninal Impact	7.5 cm below XP	330°	5.8	6.8	-
Hip Impact	Greater trochanter	270°	5.2	-	9.8

Positioning¶

The VIVA+ model is used in the default standing position. No contact is modelled between arms and impactors.

Responses recorded¶

The reference values from the paper were digitalised and are incuded in the package. The data corresponds to the unnormalised corridors.
