Shear modulus:

แปลว่า(english) The ratio of shear stress divided by the corresponding shear strain in a linear elastic material.

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.

Brasses

แปลว่า(english) Copper base alloys in which zinc is the principal alloying element. Brass is harder and mechanically stronger than either of its alloying elements copper or zinc. It is formable and ductile; develops high tensile strength with cold-working and is not heat treatable.

Aging 1

แปลว่า(english) A change in the properties of certain metal and alloys (such as steel) that occurs at ambient or moderately elevated temperatures after a hot working heat treatment or cold working operation. Typical properties impacted are hardness, yield strength, tensile strength, ductility, impact value, formability, magnetic properties, etc. See also Non-aging.

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.
