Shear modulus:
แปลว่า(english) The ratio of shear stress divided by the corresponding shear strain in a linear elastic material.
Babbitt
แปลว่า(english) An antifriction metal alloy used for bearing inserts;made of tin,antimony,lead and copper.
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.
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.
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.
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.
