Abstract
A device for assessing the solidity of a material comprising an ancillary tool () having an end (B) in the form of a point or blade, an impactor () for striking the ancillary tool (), a sensor () and a processing unit (). The ancillary tool () is placed between a material () and the impactor () and transmits the impact force generated by the impactor () to the material (). The sensor () is capable of measuring a quantity from among the impact force and the deformation of the impactor, and of supplying a measurement signal. The processing unit () is suitable for calculating, from the measurement signal, an indicator representative of the solidity of the material (). The indicator corresponds to the duration of a time window between the first peak (P) of maximum amplitude of the measurement signal and the second peak of maximum amplitude (P).
