Unformatted text preview: TENSION TEST Introduction : Tensile Test is the most common type test used to measure the mechanical properties of a material. The tension test is widely used to provide a basic design information on the strength of materials and is an acceptance test for the specification of materials. The major parameters that describe the stress-strain curve obtained during the tension test are the tensile strength (UTS), yield strength ( y ), elastic modulus (E), percent elongation (L%) and the reduction in area (RA%). Toughness, Resilience, Poissons ratio ( ) can also be found by the use of this testing technique. Objective : The aim of this experiment is to obtain the stress-strain diagram, to determine the tensile properties and hence to get valuable information about the mechanical behaviour and the engineering performance of the material. Specimen :- Specimen Type : S 235 JR G2 (According to EN norms ) ST 37 (According to DN norms)- Specimen has rectangular cross sectional area which is suitable for gripping into the jaws of the testing machine. Gage area of the specimen is smaller to ensure that failure will occur at a section where stresses are not affected by the gripping device....
