METHOD FOR MEASURING TENSION STATE OF A MATERIAL AND USES THEREOF

摘要

The invention concerns a method for determining the state of tension of a material at a given time, comprising a step which consists in calculating the value of at least one parameter extracted from the ultrasonic signal received after propagation, of an ultrasonic wave emitted in said material between an ultrasound source and at least an ultrasound emitter located at a fixed distance from said source, the value of the parameter(s) varying with the state of tension of the material, said variation of the parameter(s) being proportional or inversely proportional to the variation of the state of tension of said material.
