Strength:

แปลว่า(english) A very general term that may be applied to a material or a structure. In a material, strength refers to a level of stress at which there is a significant change in the state of the material, e.g., yielding or rupture. In a structure, strength refers to a level of level of loading which produces a significant change in the state of the structure, e.g., inelastic deformations, buckling, or collapse.

fatigue of material

แปลว่าความล้าในวัตถุ, คือความทนทานในวัตถุเ เช่น โลหะที่ใช้งานหนักมาเป็นเวลานาน ย่อมจะเกิดความล้าข้นและจะเกิดผลเสียหายในที่สุด

Centroid:

แปลว่า(english) Similar to the concept of center of gravity, except that it applies to a two dimensional shape rather than an object. For a given shape, the centroid location corresponds to the center of gravity for a thin flat plate of that shape, made from a homogeneous material.

Bonding Clay (Bonderise)

แปลว่า(english) Any clay suitable for use as a bonding material.

Free-Issue Material

แปลว่าวัสดุจัดให้เปล่า

Elastic energy:

แปลว่า(english) The energy stored in deformed elastic material (e.g., a watch spring). Elastic energy equals where k is the stiffness, and is the associated deflection. Elastic energy is sometimes called elastic potential energy because it can be recovered when the object returns to its original shape; see potential energy.

Brittle:

แปลว่า(english) A brittle structure or material exhibits low ductility, meaning that it exhibits very little inelastic deformation before complete failure.

Burnishing 2

แปลว่า(english) Smoothing surfaces through friction between the material and material such as hardened metal media.

Adsorption Water

แปลว่า(Concrete Engineering) Water held on surfaces in a material by either physical and/or chemical forces.

Burn-Out

แปลว่า(english) Firing a mold at a high temperature to remove pattern material residue.

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.

AAC - Autoclaved Aerated Concrete

แปลว่า(Concrete Engineering) Exceptionally lightweight precast concrete with high thermal qualities and fire resistence. Suitable for cutting with ordinary hand tools. Mix design is composed of portland cement, sand or siliceous material, lime, gypsum, finely powdered aluminum, and water. Initial mix is a combination of portland cement, sand, lime and gypsum to produce a slurry. Finely powdered aluminum mixed into a paste is added prior to placement into large, rail-like forms. The finely powdered aluminum reacts with the alkaline components of the cement and lime to produce hydrogen gas, which increases the volume approximately five times producing a uniformly, dispersed cellular structure. Units are cut to required shape. Units are placed in an autoclave, an enclosed pressurized chamber, and steam cured at 3500 F. Approximately 80% of the ultimate volume consists of air voids.
