Stiffness:
แปลว่า(english) This is a general term which may be applied to materials or structures. When a force is applied to a structure, there is a displacement in the direction of the force; stiffness is the ratio of the force divided by the displacement. High stiffness means that a large force produces a small displacement. When discussing the stiffness of a material, the concept is the same, except that stress substitutes for force, and strain substitutes for displacement; see modulus of elasticity.
Elastic:
แปลว่า(english) A material or structure is said to behave elastically if it returns to its original geometry upon unloading.
Brinell Hardness Testing
แปลว่า(english) Method of determining the hardness of materials; involves impressing a hardened ball of specified diameter into the material surface at a known pressure (10-mm ball, 500-kg load for aluminum alloys). The Brinell hardness number results from calculations involving the load and the spherical area of the ball impression. Direct-reading testing are generally used for routine inspection of forgings, and as a heat treat control function.
Busheling
แปลว่า(english) A widely traded form of steel scrap consisting of sheet clips and stampings from metal production. Bushel baskets were used to collect the material through World War II, giving rise to the term.
Butcher Saw Steel
แปลว่า(english) A hardened, tempered, and polished high carbon spring steel strip material (carbon content is generally higher than that of a material used for wood band saw applications) with a Rockwell value of roughly C47/49.
Vaporproof
แปลว่า(Concrete Engineering) A material that is totally immune to the passage of a gas under pressure. Any material that is truly vaporproof will inherently be waterproof.
Sacking
แปลว่า(Concrete Engineering) Removing or alleviating defects on a concrete surface by applying a mixture of sand and cement to the moistened surface and rubbing with a coarse material such as burlap.
Stucco
แปลว่า(Concrete Engineering) A portland cement mortar material that can be applied to the surface of any building or structure to form a hard and durable covering for the exterior wails or other exterior surfaces.
