Abstract
Method for measuring the resistance of a body, for example a wooden body, characterized in that a penetrating body is inserted dynamically inside the material, equipped with an appropriate level of energy and instantly released, after which the penetration of the penetration body into the interior of the material can be measured, which penetration provides a direct indication of the strength of the material.
