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)

What is flexural strength of concrete?
the ability of beam or slab to resist failure in bending is called Flexural Strength of concrete.IIt is measured as modulus of rupture
What is the main physical meaning of section modulus?
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 aggregates affect the strength of concrete?
how does the fineness modulus of aggregate affect the strength of concrete
What is the tangent modulus of mild steel?
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)
What is the plastic section modulus of steel section?
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
What is the relation between modulus of rupture and split tensile strength?
Modulus of rupture > Splitting strength > Direct tensile strength
Is tensile modulus the same as young's modulus?
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.
What is the formula of young's modulus?
[Young's Modulus] = M1L-1T-2 __> this is the dimensional formula
Is Modulus of rupture the same as Maximum stress?
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.
What is the rupture modulus of steel?
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.
What is the dimensional formula of young's modulus?
[Young's Modulus] = M1L-1T-2 __> this is the dimensional formula
What is the difference between Breaking Strength and Modulus of Rupture (ceramic tile)?
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.
Is modulus of rupture same as coefficient of thermal expansion?
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).
Modulus of Elasticity formula?
the world
What is the formula of modulus of elasticity?
e=stress/strain
Formula for bulk modulus of volume of elasticity?
K(bulk modulus of elasticity)=-{[Pressure x volume]/change in volume}
Why is m used in the slope formula?
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").
