Tensile test is the drawing of materials until they break under constant temperature in order to determine the strength properties under static (non-impact) load and to obtain the Stress-Strain diagram during this process. Tensile testing of all metal and composite materials, bolts and welded joints in our laboratory is carried out under the expert’s supervision with INSTRON 5989 SERIES PREMIUM GRADE 600 KN EM Universal test equipment. As a result of the tensile test, the following mechanical properties of the material represented by the sample can be found.
