MECHANISM FOR PRESTRESSING AND METHOD FOR DETERMINING THE MECHANICAL PROPERTIES OF ELASTOMERIC METERIALS, ANIMAL AND HUMAN TISSUES, BY PENETRATION EXPERIMENTS.

摘要

Prestressing mechanism (1) achieving a predefined elongation on a strip of elastomer (or a strip of animal or human tissue) (2), is configured by a stationary arm (3) and a mobile arm (4), which by suitable pins (5) cause an elastic elongation on the elastomer (or strip of animal/human tissue), when the arms secure in alignment by a key (6) and with lubricant in the interface (7). The strip of elastomer or human/animal tissue (2) is configured with holes at each side stressed, so that it is used by the prestressing mechanism. The strip comprises suitable incisions (22), respective to the number of holes. The invention also proposes a method for analyzing the results of the penetration experiments on an elastomeric material (or tissue) under a predefined prestressing, so that the mechanical properties of the material are obtained.
