Jacking Equipment

แปลว่า(Concrete Engineering) In prestress concrete, the device used to stress the tendons.

Jacking Force

แปลว่า(Concrete Engineering) The temporary force exerted by the jacking device which introduces tension into the tendons. Jacking Stress In prestress concrete, the maximum stress occurring in a tendon during stressing.

Strain:

แปลว่า(english) The intensity of deformation at a point in an object. See normal strain and shear strain.

ความเค้น

หมายถึง(ฟิสิกส์) น. แรงที่กระทำต่อ ๑ หน่วยพื้นที่ของเทหวัตถุ เมื่อเทหวัตถุใดถูกความเค้นมากระทำจะเกิดความเครียดขึ้นแก่เทหวัตถุนั้น. (อ. stress).

Bending Strength

แปลว่า(english) Upper limit of normal stress of a beam at which fracture or excessive plastic deformation occurs.

Yield strain:

แปลว่า(english) A material deformed beyond its yield strain, no longer exhibits linear elastic behavior. See yield stress.

Pressure:

แปลว่า(english) Pressure is a similar idea to stress, the force intensity at a point, except that pressure means something acting on the surface of an object rather than within the material of the object. When discussing the pressure within a fluid, the meaning is equivalent to stress.

Modulus of elasticity:

แปลว่า(english) The proportional constant between stress and strain for material with linear elastic behavior: calculated as stress divided by strain. Modulus of elasticity can be interpreted as the slope of the stress-strain graph. It is usually denoted as E, sometimes known as Young's Modulus Y, or E-Modulus.

Baked Strength

แปลว่า(english) Compressive, shear, tensile or transverse strength of a mold sand mixture when baked at a temperature above 231 B0F (111 B0C) and then cooled to room temperature.

Plane of Weakness

แปลว่า(Concrete Engineering) The plane along which a structure under stress will tend to fracture; may exist because of the nature of the structure and its loading, by accident, or by design.

Linear:

แปลว่า(english) A structure is said to behave linearly when its the deformation response is directly proportional to the loading (i.e. doubling the load doubles the displacement response). For a material, linear means that the stress is directly proportional to the strain.

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.
