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 to use

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. Terzaghi in 1955 (Ref. 1, P. 300) attributed this confusion to the initial work by Hayashi in

- 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.

Young's modulus E = initial slope of σt −εt curve = initial slope of σn −εn curve. Yield stress σ y is the nominal stress at the limit of elasticity in a tensile test. Tensile strength σ ts is the nominal stress at maximum load in a tensile test.

[PDF]- Flexural strength - Wikipedia

Flexural strength, also known as modulus of rupture, or bend strength, or transverse rupture strength is a material property, defined as the stress in a material just before it yields in a flexure test. The transverse bending test is most frequently employed, in which a specimen having either a circular or rectangular cross-section is bent until fracture or yielding using a three point ...

Pavement thickness design prior to the 1986 AASHTO Design Guide was based on experience, soil classification, and the plastic response of pavement materials to static load, e.g., Marshall stability for asphalt concrete and CBR for unbound materials.

- Natural Stone Institute - ASTM International Standards

Materials standards help to prevent the use of stone products for unsuitable applications. For instance, without the minimum standards for Abrasion Resistance of Stone Subjected to Foot Traffic (ASTM C241-90(1997)), it would be more likely that very soft, easily damaged materials would be installed in commercial applications.
