    THE DEFORMATION MODULUS OF ROCK MASSES - .

    2. ON DEFORMATION AND ELASTIC MODULI 2.1 Definitions Deformability is characterized by a modulus describing the relationship between the applied load and the resulting strain. The fact that jointed rock masses do not behave elastically has prompted the usage of the term modulus of deformation rather than modulus of elasticity or Young's modulus.

    Modulus of Subgrade Reaction - Which One Should be Used? By Wayne W. Walker, P.E., F.ACI and Jerry A. Holland, P.E., F.ACI The modulus of subgrade reaction is an often misunderstood and misused concept for the thickness design of slabs-on-ground.

    Flexural modulus - Wikipedia

    In mechanics, the flexural modulus or bending modulus is an intensive property that is computed as the ratio of stress to strain in flexural deformation, or the tendency for a material to resist bending.It is determined from the slope of a stress-strain curve produced by a flexural test (such as the ASTM D790), and uses units of force per area.
