Variables Used
Bending moment in curved beam - (Measured in Newton Meter) - Bending moment in curved beam is the reaction induced in a structural element when an external force or moment is applied to the element, causing the element to bend.
Bending Stress - (Measured in Pascal) - Bending stress or allowable bending stress is the amount of bending stress that can be generated in a material before its failure or fracture.
Cross Sectional Area - (Measured in Square Meter) - Cross sectional area is the area of a two-dimensional shape that is obtained when a three-dimensional shape is sliced perpendicular to some specified axis at a point.
Radius of Centroidal Axis - (Measured in Meter) - Radius of Centroidal Axis is the radius of the axis of the curved beam passing through the centroid point.
Radius of Neutral Axis - (Measured in Meter) - Radius of Neutral Axis is the radius of the axis of the curved beam passing through the points which have zero stress on them.
Eccentricity Between Centroidal and Neutral Axis - (Measured in Meter) - Eccentricity Between Centroidal and Neutral Axis is the distance between the centroidal and the neutral axis of a curved structural element.
Distance from Neutral Axis - (Measured in Meter) - The Distance from Neutral Axis is defined as the distance from an axis in the cross section of a beam or shaft along which there are no longitudinal stresses or strains.
STEP 1: Convert Input(s) to Base Unit
Bending Stress: 55 Newton per Square Millimeter --> 55000000 Pascal (Check conversion here)
Cross Sectional Area: 240 Square Millimeter --> 0.00024 Square Meter (Check conversion here)
Radius of Centroidal Axis: 80 Millimeter --> 0.08 Meter (Check conversion here)
Radius of Neutral Axis: 78 Millimeter --> 0.078 Meter (Check conversion here)
Eccentricity Between Centroidal and Neutral Axis: 6.5 Millimeter --> 0.0065 Meter (Check conversion here)
Distance from Neutral Axis: 4 Millimeter --> 0.004 Meter (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Mb = (σb*(A*(R-RN)*(e)))/y --> (55000000*(0.00024*(0.08-0.078)*(0.0065)))/0.004
Evaluating ... ...
Mb = 42.9
STEP 3: Convert Result to Output's Unit
42.9 Newton Meter -->42900 Newton Millimeter (Check conversion here)
42900 Newton Millimeter <-- Bending moment in curved beam

## What Does Fracture Toughness Mean?

In metallurgy, fracture toughness refers to a property that describes the ability of a material containing a crack to resist further fracture. Fracture toughness is a quantitative way of expressing a material's resistance to brittle fracture when a crack is present. If the material has high fracture toughness, it is more prone to ductile fracture. Brittle fracture is characteristic of materials with less fracture toughness.
Fracture toughness values may serve as a basis for:
Material comparison
Selection
Structural flaw tolerance assessment
Quality assurance
