Per ASTM C78, the flexural strength of concrete (or the Modulus of Rupture) can be derived from the following equation:
fc' = R2 / 100
where:
fc' = compressive strength (psi)
R= Modulus of Rupture (psi)
Modulus of rupture refers to a brittle material's flexibility under pressure. It is a mechanical measure for how much a material can take pressure without deformation.
the ability of beam or slab to resist failure in bending is called Flexural Strength of concrete.IIt is measured as modulus of rupture
section modulus is a measure of the strength of a beam. The more the section modulus the more is the strength.
how does the fineness modulus of aggregate affect the strength of concrete
The tangent modulus of steel varies depending on if the steel has yielded.If the steel has not yielded, and is still elastic (stresses less than approx. 275 MPa (39885 Psi) the tangent modulus will be equal to the Young's Modulus, 205 GPa (39885367)If the steel has yielded, the tangent modulus will be related by the Ramsberg-Osgood Equation, but a reasonable value to use would be approx. 1.5 GPa (2175565 Psi)
section modulus of any section is the ratio of the moment of inertia to the distance of extreem fibre from the neutral axis. plastic section modulus is the section modulus when the cross section is subjected to loading such that the whole section is under yield load. numerically it is equal to the pdoduct of the half the cross section area and the distance of center of gravity of tension and compression area from neutral axis
Modulus of rupture > Splitting strength > Direct tensile strength
Yes, indeed. Sometimes tensile modulus is different from flexural modulus, especially for composites. But tensile modulus and elastic modulus and Young's modulus are equivalent terms.
[Young's Modulus] = M1L-1T-2 __> this is the dimensional formula
Yes.Modulus of RuptureUltimate strength determined in a flexure or torsion test. In a flexure test, modulus of rupture in bending is the maximum fiber stress at failure. In a torsion test, modulus of rupture in torsion is the maximum shear stress in the extreme fiber of a circular member at failure. Alternate terms are flexural strength and torsional strength.
Modulus of rupture is the ability of a material to resist deformation when load is applied. It is used as a mechanical parameter to test the brittleness of a material. It is also known as bend strength, fracture strength, or flexural strength.
[Young's Modulus] = M1L-1T-2 __> this is the dimensional formula
The modulus of rupture is the same as the breaking strength. It is a term used for ceramics where strength is dependent upon statistical distribution of flaw size, flaw shape, and moisture.
No. The modulus of rupture is the strength of brittle material, measured in units of force per area (psi or MPa). The CTE is a measure of how much a material expands under temperature,in parts per degree (C or F).

what we now call just the "slope" was once called the "modulus of slope", the word "modulus" being used in its sense of "number used to measure" (as in "Young's modulus").
