tensile testing machine procedure

It is used to test the tensile strength of materials. During the test we record the pulling force and associated extension of the sample and analyze the data to determine the materials strength and elongation.

Introduction of Tensile Tester 1 What is a tensile tester.

. This test will be conducted on the universal testing machine. Multiplying the width and thickness within the gauge length determines the initial cross-sectional area before testing. Tensile Testing will expose the sample to a controlled amount of tension until failure occurs.

These standardized tests are often performed on electromechanical tensile tester machines. A tensile test applies tensile pulling force to a material and measures the specimens response to the stress. Figure 61 shows a tensile testing machine which looks similar to the one used in this lab.

The tensile testing machine is also called the electronic tensile testing machine. Grip the test specimen in the jaw of the Tensile Testing Device in the. Tensile testing is a destructive test process that provides information about the tensile strength yield strength and ductility of the metallic material.

Testing Machines Tensile Specimens. Debugging by the manufacturer you can also master some maintenance methods to debug it yourself. Tensile testing is used to find the behavior of the material when it is subjected to a slowly applied tensile load up to when the material gets a fracture.

Precision measurement advanced technology sophisticated software capabilities. Adjust the active pointer to the zero point move the pointer and the active pointer closer and adjust the automatic drawing device. Universal Testing Machine Fig.

The test is made by gripping the ends of a suitably prepared standardised test piece in a tensile test machine and then applying a continually increasing uni-axial load until such time as failure occurs. Standard shape tensile specimens. A dogbone sample showing dimensions consistent with ASTM A370.

Mainly used for a variety of materials for static load tensile compression bending shear tear peel and other mechanical properties of the test machine suitable for plastic plates tubes profiles plastic film rubber steel fabric and other. The data is manipulated so that it is not specific to the geometry of the test sample. It is an important type of test for determining a materials tensile strength yield strength and ductility.

The upper clamp of the device is kept fixed whereas the lower clamp is moved with a constant speed. Also known as UTM. A universal testing machine UTM also known as a universal tester materials testing machine or materials test frame is used to test the tensile strength.

Consider the typical ten- sile specimen shown in Fig. Tensile test samples are generally formed so that they have an enlarged upper and lower part called shoulders which are gripped by the tensile testing machine. The important part of the specimen is the gage section.

This test procedure creates tension on the sample which leads to sample failure or fracture. The applied strain rate must be low so that the result is not distorted. The straining or pulling device and an arrangement to measure and register the load on a dial.

Tensile Test Procedure A tensile specimen of standard dimensions machined from the metal is inserted in a tensile testing machine shown in the below figure. It measures the force required to break a composite or plastic specimen and the extent to which the specimen stretches or elongates to that breaking point. It has enlarged ends or shoulders for gripping.

During this test other material properties can also be determined to guide design or production teams in making product or component improvements. In the most basic description a tensile test involves gripping a sample at each end and pulling it apart. Tensile Test Procedure The gauge length is the reference length used in the elongation calculations.

The topic of this lab is confined to the tensile property of polymers. Tensile tests are typically conducted on electromechanical or universal testing machines are simple to perform and are fully standardized. Tensile tester machine is also called universal material testing machine.

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 -. First clamp the test piece in the upper clamp then move the lower clamp to the proper clamping position and finally clamp the lower end of the test piece. These samples are known as tensile bars.

The test process involves placing the test specimen in the testing machine and slowly extending it until it fractures. Ad Specialists in the manufacture of rheometers for rubber polymer and elastomer testing. By doing this tensile tests determine how strong a material is and how much it can elongate.

In the tensile test a material specimen is strained until it breaks. First of all we need to know why the data of the tensile testing machine is inaccurate. Set up the specimen.

This test is a destructive method in which a specimen of a standard shape and dimensions prepared according to ASTM D 638tandard test method for tensile properties of. The cross-sectional area of the gage section is re- duced relative to that of the remainder of the specimen so that deformation and failure will be. Depending on the test standard the gauge length is either 2 inches 80 mm or 50 mm.

Test pieces are standardised in order that results are reproducible and comparable as shown in Fig 2. During the tensile test the force and extension of the specimen are measured. Tensile testing device of the constant rate of elongation type capable of determining the applied load to 5 accuracy at a rate of traverse 50 5mmminuteJaw width 50mm Gauge length Variable to suit test specimens being evaluated.

Ad Materials Testing Machines from 1000 to 100000 pounds force. Now clamp the specimen onto the machine by fixing the two ends of the sample on the upper jaw and lower jaw. Next to hardness measurement tensile tests are one of the most frequently performed tests in mechanical materials testing.

This Universal Testing Machine is designed for conduct tensile compression bending shearing bonding strength peeling tearing and other tests for rubber plastic leather metal nylon line. The middle known as the gage section is more narrow and this is where deformation and failure occur during the test. Everyone knows this well.

A tensile test is a scientific test process involving the application of tension to a specimen until it fractures. The machine consists essentially of two parts. Universal Testing Machine The main parts of the Universal testing machine are.

During this process the elongation of the gauge section is recorded against the applied force. Check and test run.
