Claim:
1. A method for determining elastic properties of a spherical part, comprising; positioning an emitting transducer in a first position, the emitting transducer operating also as a receiver in said first position; emitting beams of ultrasound waves towards a point of impact on a surface of the spherical part so as to generate waves within the spherical part, the beams of ultrasound waves being emitted through a coupling fluid; determining a diameter d providing a measurement of the transmission time t providing a first measurement t displacing the emitting transducer to a second position with a second point of impact, in such a way to bring the beam to a top of the spherical part and to maintain the angle of incidence θ with the first direction D providing a second measurement t determining a Young's modulus and/or a Poisson's ratio of a material of the part based on a longitudinal velocity V
