Strain:

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

Yield strain:

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

plastic strain

แปลว่าความเครียดพลาสติก

strain gauge

แปลว่ามาตรวัดความเครียด

initial strain

แปลว่าคววามเครียดเริ่มแรก

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.

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.

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.

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.
