MODIFIED PENETRATION PIN AND METHOD FOR THE FINDING OF PROPRTIES OF ANIMAL AND HUMAN TISSUES, THROUGH PENETRATION EXPERIMENTS.

摘要

Special container of local cooling (8) of the edge of the penetrator, at a predetermined temperature, lower than the temperature of the material under examination. The container has a tank (9) where liquid or solid cooling material is stored at a lower temperature than the material under examination and a metallic membrane on the surface (10) that intercedes between the pin of the penetrator (11) and the cooling material. Modified pin of the penetrator (11) that consists of a cone that bears radial indentations (12) that override in sectors, symmetrically positioned, so as to increase the friction on the interface of pin-material. Modified pin (11), that bears radial protrusions (13), so as to reduce the friction on the interface of pin-material. Method of interpretation of the response of experiments of penetration on tissues, so as to generate their mechanical properties and therefore their physiological properties.
