Experiment tensile test essay

There are two value displaced on the displayer, one is the current force load and one is the maximum load. The threads were tightened on the chucks to ensure that the specimen was tightly helped to ensure that the process was accurate.

The machine was then connected to a switch on the interface. Make sure the Experiment tensile test essay between copper and the force measurement is fixed and tight before operate it. This process was carried out with the determination of the increasing elongation length due to the increased loading.

After that, the load vs. For metal is plastic. If smooth, is fast fracture. Lab report about tensile testing Lab report about tensile testing 8 August Technology Introduction This mechanical testing is demonstrated the relationship between stain and stress for a certain material while it undergoes a tension force.

In addition, the loading on the rod was carried and this led to the elongation of the material. The diameter was key in the determination of the area of the specimen. Another thing is we need to measure is the elongation at fracture and the reduction in area at fracture. First, the diameter of the rod, which is the specimen, was taken out by the use of the Vernier caliper.

The specimen was then placed on the machine for the test to be carried out. And elongation of amorphous tie chains so the stress-strain behavior is brittle.

The computer will record the data for every elongation and force load. Then set the X and Y vector of machine to the zero and operate the machine. This means that the loading has to be done until the fracture level of the material is reached.

And define the type of facture of them, which are two metallic, copper and low carbon steel and two polymeric, acrylic and acetone. In addition, the nuts were tightened with hands to ensure that they were firm on the specimen. This was used in order to identify the elastic limit, upper yield point and lower yield point.

Result Discussion and conclusions Popular Essays. During the experiment, different parameters, which include the diameters and length of the materials, were noted down. The process started and the elongation was measure. And because of the cross-section area is rectangle, we need to measure depth and width instead of the diameter.

It should take a while for the elongation until it broke. The loading was slowly applied, the load applied, and elongations achieved were noted out respectively. The parameters were also key in the determination of the yield strength and the percentage elongation.

The jack handle was used to apply the required load and ensure that the loading was increased accordingly each moment and the respective elongation was noted out. The specimen used had an original diameter of 6 millimeter and original length of From the breaking surface of the sample we can define the type of fracture by ease.

Background Stress-strain curves show the response of material to an applied stress. But for the polymeric, since they have different shape to metallic, they are clamped by a big metal clamp not just install it into the machine which mean install the metal clamp to two end of the connector and clamp the sample up.

The key parameters include the elongation length and the loading, which was applied. True stress and strain are calculated based on the actual dimensions of the material. Engineering stress and strain also sometimes called nominal stress and strain are calculated based on the original dimensions of the material in question.

Tensile Testing

It has to be noted that the tensile strength of the material is the final strength on which the material is able to withstand a certain load. After the experiment, several parameters were noted down in order to help in the analysis, which would lead to the determination of the tensile strength.Tensile Test Abstract The objective of this experiment is to test three specimens of different materials in a Tensile test machine and to calculate basic material characteristics such as tensile stress and Young’s Modulus.

The objective of this CDIO experiment was to determine the mechanical property of polymeric materials which was the tensile billsimas.com testing standard to adopt for the tensile testing was ASTM D Four different types of polymers were placed into the tensile testing machine.

The different. In tensile test experiment, after knowing the measurement (thickness and width) of 4 different specimens, place one of the specimens to the grips. Start the test program, when the specimen breaks, test results and Load against Extension graph.

Essay on Tensile Test Lab Report; Essay on Tensile Test Lab Report. Words Mar 21st, 9 Pages. Kimmi Dodia- Biomedical Science- Lab partner- Kim Harcourt Lab report- Experiment 1: Microbial Genetics Abstract The objective of this experiment was to introduce the study of bacterial genetics in order to identify the.

The objective of conducting tensile stress experiment is to establish the modulus of elasticity, tensile strength or ultimate strength of a material.

Lab report about tensile testing

Tensile test also helps to ascertain the nature of a material (ductile or brittle). The purpose of this test is to determine the tensile properties of a certain type of brass with different initial sizes (length, width and thickness).

Four different size combinations were tested. An Instron testing device was used to test each piece until fracture; an example of this machine can be seen in fig.
