Tensile strength (Rm) means the maximum stress a material subjected to before the pull-off. When the steel yield to a certain extent, due to the rearrangement grain interior, its ability to resist deformation increase again, this time the deformation has developed rapidly, but only as to improve the stress is increased until the stress reaches a maximum value. Thereafter, the ability of steel to resist deformation significantly reduced, and large plastic deformation occurs at the weakest point, where the specimen quickly narrow section necking phenomenon, until fracture failure. Steel before being drawn by the maximum stress value is called the breaking strength or ultimate tensile strength.
1. Noun tensile strength
Tensile strength (Rm) means the maximum stress a material subjected to before the pull-off. When the steel yield to a certain extent, due to the rearrangement grain interior, its ability to resist deformation increase again, this time the deformation has developed rapidly, but only as to improve the stress is increased until the stress reaches a maximum value. Thereafter, the ability of steel to resist deformation significantly reduced, and large plastic deformation occurs at the weakest point, where the specimen quickly narrow section necking phenomenon, until fracture failure. The maximum stress value by the steel before tensile breaking strength or ultimate tensile strength referred todegree. After
2. Definition of symbolic representations of tensile strength
during the tensile specimens, after the material into the reinforcing phase with the yield phase significantly reduced transverse cross-sectional dimension of the pull-off the maximum force (Fb), divided by the specimen original cross-sectional area (So) of the resulting stress (σ), called the tensile strength or ultimate strength (σb), units of N / mm2 (MPa). It represents the maximum capacity of the metal material to resist damage under tension. The formula is:
σ = Fb / So
where: the pull-off specimen Fb– when the maximum force, N (Newton); So – the original specimen cross- cross-sectional area, mm2.
The tensile strength was measured currently more common method is to use universal testing machine to be measured tensile / compressive strength of the material.
3. Tensioned membrane tensile strength substantially description
membrane under the effect of a pure tensile force, without break can withstand the maximum load and the stretching ratio by the width of the membrane, usually expressed as N / 5cm. It is divided into the warp and weft tensile strength.
4. The tensile strength was a basic introduction to the
Tensile strength when stretched membrane in the warp direction.
5. The weft tensile strength substantially description
Tensile strength when stretched in the weft direction membrane
