Experiment tensile test essay

The process started and the elongation was measure. Then set the X and Y vector of machine to the zero and operate the machine. This was used in order to identify the elastic limit, upper yield point and lower yield point. In addition, the nuts were tightened with hands to ensure that they were firm on the specimen.

After that, the load vs. The threads were tightened on the chucks to ensure that the specimen was tightly helped to ensure that the process was accurate.

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.

This means that the loading has to be done until the fracture level of the material is reached. Make sure the connection between copper and the force measurement Experiment tensile test essay fixed and tight before operate it.

The parameters were also key in the determination of the yield strength and the percentage elongation. True stress and strain are calculated based on the actual dimensions of the material. The diameter was key in the determination of the area of the specimen.

First, the diameter of the rod, which is the specimen, was taken out by the use of the Vernier caliper. 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.

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

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. There are two value displaced on the displayer, one is the current force load and one is the maximum load.

And because of the cross-section area is rectangle, we need to measure depth and width instead of the diameter. Another thing is we need to measure is the elongation at fracture and the reduction in area at fracture.

In addition, the loading on the rod was carried and this led to the elongation of the material. 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.

On each occasion a load was increased, the elongation achieved was noted down. If smooth, is fast fracture. The machine was then connected to a switch on the interface.

The specimen used had an original diameter of 6 millimeter and original length of Method Install the given copper cylinder into the Hounsfield H20K-W testing machines after measured the length and the diameter of it by using a Vernier caliper and a ruler.

This process was carried out with the determination of the increasing elongation length due to the increased loading. Background Stress-strain curves show the response of material to an applied stress.

During the experiment, different parameters, which include the diameters and length of the materials, were noted down.

The loading was slowly applied, the load applied, and elongations achieved were noted out respectively. From the breaking surface of the sample we can define the type of fracture by ease.

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

The key parameters include the elongation length and the loading, which was applied. The computer will record the data for every elongation and force load. It should take a while for the elongation until it broke.

And define the type of facture of them, which are two metallic, copper and low carbon steel and two polymeric, acrylic and acetone. Result Discussion and conclusions Popular Essays.

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.

For metal is plastic.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.

Lab report about tensile testing

Aims & Objective The objective of this experiment is to investigate the behaviour of different material specimens under tensile test. The materials to be investigated are brass, % carbon steel, %carbon steel and aluminium.

Tensile test is a standard engineering procedure to characterize properties related to mechanical behavior of materials.

The properties describe the response of the material during the actual loading conditions. Introduction This mechanical testing is demonstrated the relationship between stain and stress for a certain material while it undergoes a tension force.

And define the type of facture of them, which are two metallic, copper and low carbon steel and two polymeric, acrylic and acetone. 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. The objective of conducting tensile stress experiment is to establish the modulus of elasticity, tensile strength or ultimate strength of a material.

Tensile test also helps to ascertain the nature of a material (ductile or brittle) .
