METHOD OF DETERMINING TYPE AND BEHAVIOUR OF FAILURE OF CONSTRUCTION MATERIALS DURING IMPACT-WAVE LOADING Russian patent published in 2010 - IPC G01N3/30 G01N3/313 

FIELD: physics.

SUBSTANCE: method of determining type and behaviour of failure of materials of target barriers during impact-wave loading involves determination of specific mechanical momentum per unit area of the target barrier; determination of parametres of the target barrier: thickness, density of the material and speed of sound in the material; determination of type and behaviour of failure from the integrated factor of the loading condition, which is calculated using the formula: , where J_M is the specific mechanical momentum; ρ₀ and C₀ are density and sound speed, respectively, for the material of the target barrier in the initial state; H is thickness of the target barrier. If η<0.1, there is no failure, if 0.1<η<0.5 there is spallation destruction and if η>0.5 there is end-to-end penetration.

EFFECT: priori determination of type and behaviour of failure with given values of target barrier and loading parametres.
