ตัวกรองผลการค้นหา
Yield strain:
แปลว่า(english) A material deformed beyond its yield strain, no longer exhibits linear elastic behavior. See yield stress.
Linear Elastic:
แปลว่า(english) A force-displacement relationship which is both linear and elastic. For a structure, this means the deformation is proportional to the loading, and deformations disappear on unloading. For a material, the concept is the same except strain substitutes for deformation, and stress substitutes for load.
Force:
แปลว่า(english) A directed interaction between two objects that tends to change the momentum of both.Since a force has both direction and magnitude, it can be expressed as a vector
Burnt Rubber
แปลว่า(english) Small or large black spots that generally show up on surface and are generally caused by pickling steel too hot.
Bench-Blower
แปลว่า(english) A small core-blowing machine, utilizing a removable sand magazine and blow heat.
Blowhole
แปลว่า(english) A defect in a casting caused by trapped steam or gas.
Bending moment:
แปลว่า(english) A system of internal forces whose resultant is a moment. This term is most commonly used to refer to internal forces in beams.
Bell Mouth
แปลว่า(english) The flaring or tapering of a machined hole, usually made at the entrance end because of misalignment or spring of the cutting tool.
Break Test (for tempered steel)
แปลว่า(english) A method of testing hardened and tempered high carbon spring steel strip wherein the specimen is held and bent across the grain in a vice-like calibrated testing machine. Pressure is applied until the metal fractures at which point a reading is taken and compared with a standard chart of brake limitations for various thickness ranges.
Boil
แปลว่า(english) Agitation of a bath of metal caused by the liberation of a gas beneath its surface. May be deliberately induced by the addition of oxidizing material to a bath containing excess carbon. In the later case it is called a carbon boil and CO or CO2 are liberated.
Ac3
แปลว่า(english) In hypoeutectoid steel, the temperature at which transformation of ferrite into austenite is completed upon heating.
Aecm, Ae1, and Ae3
แปลว่า(english) Equilibrium transformation temperatures in steel.
