Half crack length given stress intensity factor Solution

STEP 0: Pre-Calculation Summary

Formula Used

Half Crack Length = ((Stress Intensity Factor/Tensile Stress at Crack Edge)^2)/pi
a = ((K_o/σ)^2)/pi
This formula uses 1 Constants, 3 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Variables Used

Half Crack Length - (Measured in Meter) - Half Crack Length represents half of the length of a surface crack.
Stress Intensity Factor - (Measured in Pascal sqrt(meter)) - Stress Intensity Factor specifies the stress intensity at the tip of the crack.
Tensile Stress at Crack Edge - (Measured in Pascal) - Tensile Stress at Crack Edge is the amount of tensile stress at the edge of the crack of a structural member.

STEP 1: Convert Input(s) to Base Unit

Stress Intensity Factor: 4.854065 Megapascal sqrt(meter) --> 4854065 Pascal sqrt(meter) (Check conversion here)
Tensile Stress at Crack Edge: 50 Newton per Square Millimeter --> 50000000 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

a = ((K_o/σ)^2)/pi --> ((4854065/50000000)^2)/pi

Evaluating ... ...

a = 0.00300000027021983

STEP 3: Convert Result to Output's Unit

0.00300000027021983 Meter -->3.00000027021983 Millimeter (Check conversion here)

FINAL ANSWER

3.00000027021983 ≈ 3 Millimeter <-- Half Crack Length

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
