Mathematically, Flexural strength σ = F/A where, F = Axial force, and A = Cross-sectional area of the object. The flexural strength is expressed as Modulus of Rupture (MR) in psi (MPa) and is determined by standard test methods ASTM C 78 (thirdpoint loading). The International Standard unit of Flexural Modulus is the pascal (Pa or N/m 2 or m-1.kg.s-2). Table 4. 29000 ksi) Note: For standard doubly symmetric I-shapes: r ts , r y , J, S x , h O , I y , C w , and most of the other variables can all be found in Table 1 of the AISC 360 Steel Construction Manual [1] . The comparative chart showing flexural strength values of all groups was listed in .A P value less than 0.01 was considered as significant. It is equal or slightly larger than the failure stress in tension. I have been looking everywhere, but cannot find a single website with any relevant data. This web applet, based on various established correlation equations, allows you to quickly convert between compressive strength, flexural strength, split tensile strength, and modulus of elasticity of concrete. 0
