Distance from Neutral Axis of a curved beam is defined as the distance from an axis in the cross-section of a curved beam along which there are no longitudinal stresses or strains. This parameter is crucial in analyzing stress distribution in curved structural elements.
The calculator uses the formula:
Where:
Explanation: The formula calculates the distance from the neutral axis based on the difference between the centroidal axis radius and the inner fiber radius, multiplied by 2.
Details: Accurate calculation of the distance from the neutral axis is essential for determining stress distribution, bending moments, and structural integrity in curved beam designs. It helps engineers ensure proper load-bearing capacity and prevent structural failures.
Tips: Enter the radius of centroidal axis and radius of inner fibre in meters. Both values must be positive, and the centroidal radius must be greater than the inner fiber radius for valid results.
Q1: What is the neutral axis in a curved beam?
A: The neutral axis is the line in the cross-section of a beam where there is no longitudinal stress or strain when the beam is subjected to bending.
Q2: Why is the distance from neutral axis important?
A: This distance helps determine the bending stress distribution across the beam's cross-section, which is crucial for structural analysis and design.
Q3: Can this formula be used for all curved beam shapes?
A: This specific formula is designed for rectangular curved beams. Different cross-sectional shapes may require different formulas.
Q4: What units should be used for input values?
A: Both radius values should be entered in meters (m) for consistent results.
Q5: What if the centroidal radius is smaller than the inner fiber radius?
A: This would indicate invalid geometry as the centroidal axis should always be located further from the center of curvature than the inner fiber.
