METHOD OF RESILIENT PROPERTIES ULTRASONIC MEASUREMENT Russian patent published in 2016 - IPC G01N29/07 

FIELD: machine building.

SUBSTANCE: invention can be used for determining elastic properties of part with curved surface. Summary consists in that is radiation of ultrasonic waves beams is performed in direction of part surface incidence point so, that to generate waves in said part; wherein knowing part thickness d₁ in said incidence point in first direction D₁, perpendicular to tangent plane in this point, and thickness d₂ in second direction D₂, which forms certain angle α relative to first direction, performing first measurement of time t₁, required to transmitted longitudinal waves for passage of distance d₁ from said incidence point, second measurement of time t₂, required to transmitted transverse waves for passage of distance d₂ from said incidence point, determining Young's modulus and/or Poisson coefficient of material based on longitudinal V_L= d₁/t₁ and transverse V_T= d₂/t₂ speeds.

EFFECT: technical result is possibility of curved shape parts nondestructive inspection.
