Ultimate strength is used for materials that yield before breaking, like metals; rupture strength is for materials that break suddenly, like glass. Ultimate rupture strength would imply some yield strength before finally breaking and is not a preferred term for brittle materials like glass.
Modulus of rupture > Splitting strength > Direct tensile strength
Brittle materials such as ceramics do not have a yield point. For these materials the rupture strength and the ultimate strength are the same, therefore the stress-strain curve would consist of only the elastic region, followed by a failure of the material.
trs=1.5fl/bt2
402 kN at rupture
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.
Modulus of rupture > Splitting strength > Direct tensile strength

Breaking strength is force per unit area (pounds per square inch (psi) or Megapascals (MN/sq meter) and is the value at which a material will fail, or break. It is also known as ultimate strength for ductile materials or modulus of rupture for brittle materials

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.

Ultimate Tensile Strength is the (BHN*500)
The ultimate strength of annealed SS304 is 80,000 psi (550 MPa). Its yield strength is 30,000 psi, and its shears strength is 80000/(SQRT(3)) = 46000 psi. If it is cold worked, as for bolts, its yield and ultimate and shear strength will increase.
Per ASTM C78, the flexural strength of concrete (or the Modulus of Rupture) can be derived from the following equation:fc' = R2 / 100where:fc' = compressive strength (psi)R= Modulus of Rupture (psi)
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.
