Abstract [English] A tensile test machine for performing mechanical test on a reinforcing material comprises a first crosshead (104), a second crosshead (106) and a hollow hydraulic jack (102) that the hollow hydraulic jack (102) is configured to encompass the reinforcing material. Also, four grippers (122,124,126,128) is mounted within the first crosshead (104) and the second crosshead (106), respectively to fix the ends of the reinforcing material. Using such a mechanism cause devolving a cost-effective, light-weight, and portable tensile test machine that can be easily used in any place that needed. [French] L'invention concerne une machine d'essai de traction permettant d'effectuer un essai mécanique sur un matériau de renforcement, comprenant une première traverse (104), une seconde traverse (106) et un cric hydraulique creux (102), le cric hydraulique creux (102) étant configuré de manière à englober le matériau de renforcement. En outre, quatre pinces (122, 124, 126, 128) sont montées dans la première traverse (104) et la seconde traverse (106), respectivement, pour fixer les extrémités du matériau de renforcement. L'utilisation d'un tel mécanisme a permis de concevoir une machine d'essai de traction rentable, légère et portative qui peut être facilement utilisée partout où cela est nécessaire.
