How to Calculate and Solve for Radius of Curvature | Stress Concentration Factor | Polymer Deformation
Last Updated on December 11, 2021
The image above represents radius of curvature.
To compute for radius of curvature, two essential parameters are needed and these parameters are Half Minor Axis (b) and Half Major Axis (a).
The formula for calculating radius of curvature:
ρ = b² / a
Where:
ρ = Radius of Curvature | Stress Concentration Factor
b = Half Minor Axis
a = Half Major Axis
Let’s solve an example;
Find the radius of curvature when the half minor axis is 42 and half major axis is 6.
This implies that;
b = Half Minor Axis = 42
a = Half Major Axis = 6
ρ = b² / a
ρ = (42)² / 6
ρ = 1764 / 6
ρ = 294
Therefore, the radius of curvature is 294 m.
Calculating the Half Minor Axis when the Radius of Curvature and the Half Major Axis is Given.
b = √ρ x a
Where:
b = Half Minor Axis
ρ = Radius of Curvature | Stress Concentration Factor
a = Half Major Axis
Let’s solve an example;
Find the half minor axis when the radius of curvature is 20 and the half major axis is 4.
This implies that;
ρ = Radius of Curvature = 20
a = Half Major Axis = 4
b = √ρ x a
b = √20 x 4
b = √80
b = 8.94
Therefore, the half minor axis is 8.94.
Calculating the Half Major Axis when the Radius of Curvature and the Half Minor Axis is Given.
a = b2 / ρ
Where:
a = Half Major Axis
ρ = Radius of Curvature | Stress Concentration Factor
b = Half Minor Axis
Let’s solve an example;
Find the half major axis when the radius of curvature is 12 and the half minor axis is 2.
This implies that;
ρ = Radius of Curvature = 12
b = Half Minor Axis = 2
a = b2 / ρ
a = 22 / 12
a = 4 / 12
a = 0.33
Therefore, the half major axis is 0.33.
