The image above represents flexural strength for circular cross-section in defects.
To compute for flexural strength for circular cross-section in defects, three essential parameters are needed and these parameters are Load at fracture (Ff), Specimen radius (R) and Distance between support Points (L).
The Formula for Calculating Flexural Strength for Circular Cross-section in Defects
σfs = FfL / πR³
Where:
σfs = Flexural Strength
L = Distance between Support Points
Ff = Load at Fracture
R = Specimen Radius
Lets’s solve an example;
Find the flexural strength when the distance between support points is 30, load at fracture is 21 and the specimen radius is 11.
This implies that;
L = Distance between Support Points = 30
Ff = Load at Fracture = 21
R = Specimen Radius = 11
σfs = FfL / πR³
σfs = (21)(30) / π(11)³
Then, σfs = (630) / π(1331)
σfs = (630) / (4181.4)
σfs = 0.150
Therefore, the flexural strength for circular cross-section is 0.150 Pa.

Let’s solve an example;
Find the distance between support points when the flexural strength is 44, load at fracture is 3 and specimen radius is 20.
This implies that;
σfs = Flexural Strength = 44
Ff = Load at Fracture = 3
R = Specimen Radius = 20
L = σfs x πR³ / Ff
L = 44 x π x 3³ / 20
So, L = 44 x π x 27 / 20
L = 3732.2 / 20
L = 186.61
Therefore, the distance between support point is 186.61.

Calculating the Load at Fracture when the Flexural Strength, the Specimen Radius and the Distance Between Support Point are Given
Ff = σfs x πR³ / L
Where;
Ff = Load at Fracture
σfs = Flexural Strength
L = Distance between Support Points
R = Specimen Radius
Let’s solve an example;
Find the load at fracture when the distance between support points is 14, the flexural strength is 7 and the specimen radius is 4.
This implies that;
σfs = Flexural Strength = 7
L = Distance between Support Points = 14
R = Specimen Radius = 4
Ff = σfs x πR³ / L
Ff = 7 x π x 4³ / 14
That is, Ff = 7 x π x 64 / 14
Ff = 1407.4 / 14
Ff = 100.5
Therefore, the load at fracture is 100.5.

Calculating the Specimen Radius when the Flexural Strength, the Distance Between Support Points and the Load at fracture are Given
R = 3√(FfL / σfs x 1 / π)
Where;
R = Specimen Radius
σfs = Flexural Strength
L = Distance between Support Points
Ff = Load at Fracture
Let’s solve an example;
Find the specimen radius when the flexural strength is 18, the distance between support points is 11 and the load at fracture is 7.
This implies that;
σfs = Flexural Strength = 18
L = Distance between Support Points = 11
Ff = Load at Fracture = 7
R = 3√(FfL / σfs x 1 / π)
That is, R = 3√(7 x 11 / 18 x 1 / π)
R = 3√(77 / 18 x 0.318)
R = 3√(4.27 x 0.318)
So, R = 3√1.35786
R = 1.107
Therefore, the specimen radius is 1.107.
