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.

Device for checking armor

A screening element in the form of a sintered monolithic body has an outer face and an opposing inner face with an area of the faces greater than 100 cmand the mean thickness Ebetween the faces greater than 4 mm. At least a portion of the outer face is textured such that Ai decreases from the inner face from a value of i greater than at least 50, A≥0.2×Aand A<0.9×A, 0.03×A<A<0.5×Aand A<0.1×A. Ai being the area occupied by the material alone along a plane i of internal section at the intermediate thickness Eand i corresponding in percentage to the fraction of the mean thickness Eat plane i.
