Experiment 4 - testing of materials in tension object: the object of this experiment is to measure the tensile properties of two polymeric materials, steel and aluminum at a constant strain rate on the tension testing machine. Tensile test report user description: the purpose of this experiment is to extract data on the material properties of two specimens (aluminium and steel rod), using a tensile testing machine. Applied technical services has an extensive tensile testing lab with a wide range of capabilities our services can measure your materials force limitations giving you better understanding of its quality and strength. The tensile testing laboratory was conducted using an instron load frame and the bluehill used for this lab report was not gathered from the student run experiments, but rather during a tensile test, and to compare both to the engineering stress and the engineering. In a tensile test of mild steel specimen, usually a round or flat bar is gradually pulled in a testing machine until it breaks two points, called gauge points, are marked on the central portion.
2 / tensile testing, second edition fig 2 systems for gripping tensile specimens for round specimens, these include threaded grips (a), serrated wedges (b), and, for butt end specimens, split collars constrained by a solid collar (c. The dynamic tensile test rich st coeur, manager of new technology platform development, the results of shear tests are easy to record and report these benefits and subsequent of a tensile test as an indirect measure of creep resistance was considered this idea entailed a test. Element specializes in providing industry leading tensile testing services for a wide range of metallic and polymer materials our state-of-the-art tensile testing laboratories provide conditions for exposing the resistance of materials to a static or slowly applied force.
Precaution to be taken while performing tensile strength test tensile testing is one of the most commonly used testing procedures in a wide range of industries it is meant to determine the tensile strength of the materials which are used in the industries for manufacturing of distinct products. The phenomenology of the tensile test is re-examined with special attention to the influence of strain rate sensitivity of the flow stress explicit formulae are deduced for the measured variables. 14 testing of steel 141 marking of steel 143 tensile test tensile test is one of the most common tests for steel the test is described by standard en 10 002 note: integral part of the laboratory report is stress-strain diagram, obtained from testing machine, completed by axes, description and scale. Tension test 1 object the purpose of this experiment is to understand the uniaxial tensile testing and provide knowledge report in your laboratory reports must have the followings a) cover b) a short introduction c) all the necessary calculations using measured data. 11 this test method covers the determination of the tensile properties of unreinforced and reinforced plastics in the form of standard dumbbell-shaped test specimens when tested under defined conditions of pretreatment, temperature, humidity, and testing machine speed.
Dogbone specimen geometry used for tensile test the test specimen is held fixed while the other end is pulled in uniaxial tension collinear with the long axis of the sample the forces throughout the sample and test machine are constant, but the stress varies with cross sectional area. Practical 7 : universal tensile test on mild steel and brass specimens introduction: the universal tensile test is to determine the strength of materials during the test, the specimen elongation, reduction and applied load are measured. Figure 1 shows a tensile testing machine similar to the one used in this lab this test is a destructive method, in which a specimen of a standard shape and dimensions (prepared according to astm d 638: standard test method for tensile properties of plastics) is subjected to an axial load.
Tensile testing lab report machined used for the tensile testing were non-metallic instron tensile test machine, and metallic horizontal tensile test machine. Nippon steel technical report no 95 january 2007 - 30 - 3 mechanical model of stresses in laser welded lap joints under tensile shear test although it is possible to experimentally determine the strength. Mch t 214 tensile test report: the tensile test report is to be about 350 words long, and should describe the testing performed, the results obtained, and some discussion of the results and the errors possible in the data. Basic principle and practical procedure of the tensile test on ductile metallic materials - testing machine (inspekt 200 kn, hegewald & peschke meß- und prüftechnik gmbh), specimen, extensometer.
The objective of this cdio experiment was to determine the mechanical property of polymeric materials which was the tensile properties the testing standard to adopt for the tensile testing was astm d638 four different types of polymers were placed into the tensile testing machine the different. Testing may be used to determine basic properties, such as yield or proof stress and ultimate tensile strength plus elongation alternatively it may be used to confirm proof load and ultimate load capacity of a component such as a bolt weld. In the material testing laboratory, tensile test was done on a mild steel specimen as figure 4 to identify the young’s modulus, ultimate tensile strength, yield strength and percentage elongation. Tensile testing of steel see web for typical report format including: title page, abstract, table of contents, list of table, list of figures 10 - introduction see general lab report format in appendix a 20 - data analysis microsoft word - steel_tensile_labdoc.
Uniaxial tension and compression testing of materials nikita khlystov jennie zheng 3032 lab report september 25, 2013 i introduction understanding material mechanics is critical for engineering the uniaxial tension and tensile testing. Pdf laboratory 3 tensile testing - suranaree university of. Tensile testing of metals is a destructive test process that provides information about the tensile strength, yield strength and ductility of the material laboratory testing inc, near philadelphia, pa in the united states, performs the tensile test in accordance with industry standards and specifications, including astm tensile test methods.
