method of detecting experimental module elastic objects, specimens, or semi-finished supplies

摘要

Experimental method to detect the elastic modulus (E) of objects, samples, or semi-worked products, comprising the step of imparting a mechanical stress to the sample object (100) by means of an impact generated by a beating element (2) with respect to an inertial body (3); introducing an exciting body (5) of predetermined mass (m) between the beating element (2) and the sample object (100) so that the exciting body (5) is disposed in contact with the sample object (100) in correspondence with a contact surface (5a) having a predetermined extension value (S); imparting the mechanical stress on the sample object (100) by impacting the beating element (2) on the exciting body (5); acquiring a response signal corresponding to an elongation variation (”X) of the sample object (100); processing a value of the elastic modulus (E) of the sample object (100) as a function at least of the extension value (S) of the contact surface (5a) and the value of an elongation variation (”X) of the sample object (100).
