(english) The ratio of shear stress divided by the corresponding shear strain in a linear elastic material.
(english) A hardened, tempered, and polished high carbon spring steel strip material (carbon content is generally higher than that of a material used for wood band saw applications) with a Rockwell value of roughly C47/49.
(Concrete Engineering) Having cement-like, cementing, or bonding type properties. Material or substance producing bonding properties or cement-like materials.
(Environmental Engineering) A surface phenomena in which a solute (soluble material) concentrates or collects at a surface (the adsorbent).
(english) A material or structure is said to behave elastically if it returns to its original geometry upon unloading.
(english) A brittle structure or material exhibits low ductility, meaning that it exhibits very little inelastic deformation before complete failure.
(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.
(Environmental Engineering) The controlled aerobic degradation of organic wastes into a material which can be used for landscaping, landfill cover, or soil conditioning.
(english) Natural – sandstone,emery,corundum,diamonds, or Artificial – silicon carbide,aluminum oxide – material used for making grinding wheels,andpaper,abrasive and lapping compunds.
(english) A hardened steel bar or plate that is shaped accordidng to the operation to be performed and the material to be machined.
(Concrete Engineering) The colloidal gel (glue like) material that makes up the major portion of the porous mass of which hydrated cement paste is composed.
(english) Stability is best defined as the opposite of instability, which is the occurrence of large structural deformations which are not the result of material failure.
