Abstract

The invention relates to a machine (1) for determining the fatigue life of the elastic materials (EM), comprising - an upper shaft (1.1) applying a stress (or a pressure) by being bent at the predetermined values of an angle to an elastic material (EM), a lower shaft (1.2) on which said elastic material (EM) is positioned and which rotates the elastic material (EM) around its own axis (a symmetry axis), a drive shaft (1.3) mounted to said lower shaft (1.2), a drive member (1.4) which rotates the drive shaft (1.3) at a predetermined rotation speed, a bending member (1.5) which enables the upper shaft (1.1) to apply a stress to the elastic material (EM) by bending the upper shaft (1.1) by a predetermined angle, a pushing member (1.6) which enables said bending member (1.5) to angle the upper shaft (1.1), and a detector (1.7) for measuring a force value formed by the elastic material (EM) in the opposite direction to the force applied thereto.
