Abstract
A device that includes a piece of armor made from a material that has a domain of plastic deformation under bad before breaking and an elastic deformation domain. The plastic deformation domain represents less than 1% of the elastic deformation domain. The device includes a deformation sensor fixed to the piece of armor and configured to deform plastically under the effect of at least a stress applied to the piece of armor and leading to damage of the piece of armor.
Claims23
A device including:
- a piece of armor, and
- a deformation sensor fixed to the piece of armor and configured to deform under the effect of a stress Ca applied to the piece of armor,
- elastically when the applied stress Ca is less than or equal to a threshold stress Cs, and plastically when the applied stress Ca is greater than the threshold stress Cs,
- the threshold stress being such that Cs<Cemin,
- Cemin being a minimum damaging stress for the piece of armor.
