Encyclopedia > Tensile test

Tensile stress (or tension) is the stress state leading to expansion (volume and/or length of a material tends to increase). In the uniaxial manner of tension, tensile stress is induced by pulling forces across a bar, specimen etc. Tensile stress is the opposite of compressive stress. In physics, tension is a force on a body directed to produce strain (extension); it can be considered to be negative compression. ... Stress tensor In physics, stress is the internal distribution of forces within a body that balance and react to the loads applied to it. ... In physics, tension is a force on a body directed to produce strain (extension); it can be considered to be negative compression. ... This article is about &c. ... Compressive stress is the stress applied to materials resulting in their compaction (decrease of volume). ...


Structural members in direct tension are ropes, soil anchors and nails, bolts, etc. Beams subjected to bending moments may include tensile stress as well as compressive stress and/or shear stress. Rope is also the title of a movie by Alfred Hitchcock Coils of rope used for long-line fishing A rope is a length of fibers, twisted or braided together to improve strength, for pulling and connecting. ... For the heavy metal band see Soil (band) Soil is the layer of minerals and organic matter, in thickness from centimetres to a metre or more, on the land surface. ... The purpose of a ships or boats anchor is to attach the vessel to the ground at a specific point. ... A pile of nails This article is about nails as used in engineering. ... This article refers to the threaded fastener. ... A beam is a structural element that carries load primarily in bending (flexure). ... See also moment (mathematics) for a more abstract concept of moments that evolved from this concept of physics. ... Shear stress is a stress state where the shape of a material tends to change (usually by sliding forces - torque by transversely-acting forces) without particular volume change. ...


Tensile stress may be increased until the reach of tensile strength, namely the limit state of stress. The tensile strength of a material is the maximum amount of tensile stress that it can be subjected to before it breaks. ...


See also: tension, shear stress, physics, tensile strength, strength of materials, Hooke's law. In physics, tension is a force on a body directed to produce strain (extension); it can be considered to be negative compression. ... Shear stress is a stress state where the shape of a material tends to change (usually by sliding forces - torque by transversely-acting forces) without particular volume change. ... The willingness to question previously held truths and search for new answers resulted in a period of major scientific advancements, now known as the Scientific Revolution. ... The tensile strength of a material is the maximum amount of tensile stress that it can be subjected to before it breaks. ... Strength of materials is the scientific area of applied mechanics for the study of the strength of engineering materials and their mechanical behaviour in general (such as stress, deformation, strain and stress-strain relations). ... In physics, Hookes law of elasticity states that if a force (F) is applied to an elastic spring or prismatic rod (with length L and cross section A), its extension is linearly proportional to its tensile stress σ and modulus of elasticity (E): ΔL = 1/E × F × L/A...

Tensile Properties (1988 words)
A tensile test is a fundamental mechanical test where a carefully prepared specimen is loaded in a very controlled manner while measuring the applied load and the elongation of the specimen over some distance.
Tensile tests are used to determine the modulus of elasticity, elastic limit, elongation, proportional limit, reduction in area, tensile strength, yield point, yield strength and other tensile properties.
From this point on in the tensile test, some permanent deformation occurs in the specimen and the material is said to react plastically to any further increase in load or stress.
The Ductile Iron News - New Developments in Sand Testing (3520 words)
Tensile strength has been the conventional test used to control the strength characteristics of the sand, but the tensile strength test is quite variable as far as repeatability, and is not sensitive enough to humidity which can cause deterioration of cores.
In this test, two standard test specimens are rotated in a screen for one minute, and the weight percent of sand that abrades from the surface is measured.
This test is very similar to the old mold permeability test, except that the readings are the reverse (dense molds have lower permeabilities), and the MQI package is more portable and uses more modern technology including a digital readout.
