Maximum stress at crack tip Solution

STEP 0: Pre-Calculation Summary
Formula Used
Maximum Stress at Crack Tip = Stress Concentration Factor*Applied stress
σmax = k*σ
This formula uses 3 Variables
Variables Used
Maximum Stress at Crack Tip - (Measured in Pascal) - Maximum Stress at Crack Tip is the maximum amount of stress at the tip of a crack.
Stress Concentration Factor - The Stress Concentration Factor is simply a measure of the degree to which external stress is amplified at the tip of a crack.
Applied stress - (Measured in Pascal) - Applied stress is denoted by the symbol σ.
STEP 1: Convert Input(s) to Base Unit
Stress Concentration Factor: 22 --> No Conversion Required
Applied stress: 93.3 Pascal --> 93.3 Pascal No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
σmax = k*σ --> 22*93.3
Evaluating ... ...
σmax = 2052.6
STEP 3: Convert Result to Output's Unit
2052.6 Pascal --> No Conversion Required

Failure Testing in Materials Calculators

Critical stress for crack propagation
​ Go Critical stress = sqrt(2*Young's Modulus*Specific surface energy/(pi*Crack Length))
Percent cold work
​ Go Percent cold work = 100*(Cross-sectional Area-Area after deformation)/Cross-sectional Area
Percent reduction in area
​ Go Percent reduction in area = (Cross-sectional Area-Fracture area)*100/Cross-sectional Area
Percent elongation
​ Go Percent elongation = (Fracture Length-Original Length)*100/Original Length

Maximum stress at crack tip Formula

Maximum Stress at Crack Tip = Stress Concentration Factor*Applied stress
σmax = k*σ

Effect of crack dimensions on the maximum stress

For a relatively long microcrack that has a small tip radius of curvature, the stress concentration can be very large. Thus, the maximum stress at the crack tip can be sufficient to cause fracture.
