Ductility: Ability of a material to deform under tensile load (% elongation). It is the property of a material by which it can be drawn into wires under the action of tensile force. A ductile material must have a high degree of plasticity and strength so that large deformations can take place without failure or rupture of the material.
The ultimate tensile strength of a material is an intensive property; therefore its value does not depend on the size of the test specimen.However, depending on the material, it may be dependent on other factors, such as the preparation of the specimen, the presence or otherwise of surface defects, and the temperature of the test environment and material.
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 strength of materials is determined using various methods of calculating the stresses and strains in structural members, such as beams, columns, and shafts. The methods employed to predict the response of a structure under loading and its susceptibility to various failure modes takes into account the properties of the materials such as its yield strength, ultimate strength, Young's modulus ...
This region starts as the stress goes beyond the yielding point, reaching a maximum at the ultimate strength point, which is the maximal stress that can be sustained and is called the ultimate tensile strength (UTS). In this region, the stress mainly increases as the material elongates, except that for some materials such as steel, there is a ...
Magnesium casting proof stress is typically 75–200 MPa, tensile strength 135–285 MPa and elongation 2–10%. Typical density is 1.8 g/cm 3 and Young's modulus is 42 GPa. [5]
For iron, aluminium, and copper alloys, is typically 0.4 times the ultimate tensile strength. Maximum typical values for irons are 170 MPa (24 ksi), aluminums 130 MPa (19 ksi), and coppers 97 MPa (14 ksi). [2] Note that these values are for smooth "un-notched" test specimens.
The tensile yield strength of A514 alloys is specified as at least 100 ksi (689 MPa) for thicknesses up to 2.5 inches (63.5 mm) thick plate, and at least 110 ksi (758 MPa) ultimate tensile strength, with a specified ultimate range of 110–130 ksi (758–896 MPa). Plates from 2.5 to 6.0 inches (63.5 to 152.4 mm) thick have specified strength of ...
