Interactions
Human -> Object
e.g. Human inside a car against wall
Object -> Human
e.g. Hockey Ball against hockey player
Human <-> Object
e.g. frontal shock between car and truck
Physical
mechanism
When an impact occurs the kinetic energy
of the moving mass is entirely transferred
to the human (conservative model)
Device's
Characteristics
High energy
dissipation
Without permanent deformation
(keeping the shape)
Repetitive usage
e.g. sports
With permanent
deformation
Unique usage
e.g. accidents,
e.g. shootings
