Stress Intensity factor for cracked plate Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

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.
Half Crack Length - (Measured in Meter) - Half Crack Length represents half of the length of a surface crack.

STEP 1: Convert Input(s) to Base Unit

Tensile Stress at Crack Edge: 50 Newton per Square Millimeter --> 50000000 Pascal (Check conversion here)
Half Crack Length: 3 Millimeter --> 0.003 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

K_o = σ*(sqrt(pi*a)) --> 50000000*(sqrt(pi*0.003))

Evaluating ... ...

K_o = 4854064.78138925

STEP 3: Convert Result to Output's Unit

4854064.78138925 Pascal sqrt(meter) -->4.85406478138925 Megapascal sqrt(meter) (Check conversion here)

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
