Brittle Fracture 2

แปลว่า(english) Fracture preceded by little or negligible plastic deformation.

Brittleness

แปลว่า(english) The tendency of a metal or material to fracture without undergoing appreciable plastic deformation.

Trickling filter

แปลว่า(Environmental Engineering) An attached growth biological process in which the microbial film is attached to non-moving rock or plastic media.

Chemical fixation (or stabilization/solidification)

แปลว่า(Environmental Engineering) A term for several different methods of chemically immobilizing hazardous materials into a cement, plastic, or other matrix.

BACK-UP RING

แปลว่า(english) A fabric or plastic device that is used with an o-ring or other gasket to prevent extrusion of the o-ring or gasket into an adjacent space or crevice

พลาสติก

หมายถึงน. สารประกอบอินทรีย์ที่สังเคราะห์ขึ้นใช้แทนวัสดุธรรมชาติ บางชนิดเมื่อเย็นก็แข็งตัว เมื่อถูกความร้อนก็อ่อนตัว บางชนิดแข็งตัวถาวร มีหลายชนิด เช่น ไนลอน ยางเทียม ใช้ทำสิ่งต่าง ๆ เช่น เสื้อผ้า ฟิล์ม ภาชนะ ส่วนประกอบเรือหรือรถยนต์. (อ. plastic).

Inelastic:

แปลว่า(english) Not surprisingly, the opposite of elastic. A deformation of a structure or material under load is described as inelastic when the deformation remains after the load is removed. The term plastic is often used with the same meaning.

Chlorofluorocarbons

แปลว่า(Environmental Engineering) Synthetic organic compounds used for refrigerants, aerosol propellants (prohibited in the U.S.), and blowing agents in plastic foams. CFCs migrate to the upper atmosphere destroying ozone and increasing global warming. Typical atmospheric residence times are 50 to 200 years.

Revibration

แปลว่า(Concrete Engineering) Delayed vibration of concrete that has already been placed and consolidated. Most effective when done at the latest time a running vibrator will sink of its own weight into the concrete and make it plastic and workable again.

Ductility:

แปลว่า(english) Ductility generally refers to the amount of inelastic deformation which a material or structure experiences before complete failure. Quantitatively, ductility can be defined as the ratio of the total displacement or strain at failure, divided by the displacement or strain at the elastic limit.

Age Hardening

แปลว่า(english) Hardening by aging, usually after rapid cooling or cold working. The term as applied to soft, or low carbon steels, relates to a wide variety of commercially important, slow, gradual changes that take place in properties of steels after the final treatment. These changes, which bring about a condition of increased hardness, elastic limit, and tensile strength with a consequent loss in ductility, occur during the period in which the steel is at normal temperatures.
