Tensile testing, also known as tension testing, [1] is a fundamental materials science and engineering test in which a sample is subjected to a controlled tension until failure. Properties that are directly measured via a tensile test are ultimate tensile strength , breaking strength , maximum elongation and reduction in area. [ 2 ]
The success of a biaxial tensile test is strictly related to the shape of the specimen. [17] The two most used geometries are the square and cruciform shapes. Dealing with fibrous materials or fibres reinforced composites , the fibres should be aligned to the load directions for both classes of specimens, in order to minimize the shear stresses ...
Tensile test. A standard specimen is subjected to a gradually increasing load (force) until failure occurs. The resultant load-displacement behaviour is used to determine a stress–strain curve, from which a number of mechanical properties can be measured.
This test is performed on a universal testing machine (tensile testing machine or tensile tester) with a three-point or four-point bend fixture. The main advantage of a three-point flexural test is the ease of the specimen preparation and testing.
A compact tension specimen (CT) is a type of standard notched specimen in accordance with ASTM [1] and ISO [2] standards. Compact tension specimens are used extensively in the area of fracture mechanics and corrosion testing, in order to establish fracture toughness and fatigue crack growth data for a material.
Typical lectromechanical Universal Testing Machine Test fixture for three point flex test. A universal testing machine (UTM), also known as a universal tester, [1] universal tensile machine, materials testing machine, materials test frame, is used to test the tensile strength (pulling) and compressive strength (pushing), flexural strength, bending, shear, hardness, and torsion testing ...
In the 4-point bending test, the specimen is placed on two supports and loaded in the middle by a test punch with two loading points. This results in a constant bending moment between the two supports. Consequently, a shear-free zone is created, where the specimen is subjected only to bending.
