Theoretical Stress Concentration Factor Solution

STEP 0: Pre-Calculation Summary
Formula Used
Theoretical Stress Concentration Factor = Highest Value of Actual Stress near Discontinuity/Nominal Stress
kt = σamax/σo
This formula uses 3 Variables
Variables Used
Theoretical Stress Concentration Factor - Theoretical Stress Concentration Factor is defined as the ratio of the highest value of actual stress near discontinuity to nominal stress obtained by elementary equations for minimum cross-section.
Highest Value of Actual Stress near Discontinuity - (Measured in Pascal) - The Highest Value of Actual Stress near Discontinuity is the maximum value of stress in the specimen and is near discontinuity.
Nominal Stress - (Measured in Pascal) - Nominal Stress is the value of the stress at the minimum cross-section.
STEP 1: Convert Input(s) to Base Unit
Highest Value of Actual Stress near Discontinuity: 62 Newton per Square Millimeter --> 62000000 Pascal (Check conversion here)
Nominal Stress: 25 Newton per Square Millimeter --> 25000000 Pascal (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
kt = σamaxo --> 62000000/25000000
Evaluating ... ...
kt = 2.48
STEP 3: Convert Result to Output's Unit
2.48 --> No Conversion Required
FINAL ANSWER
2.48 <-- Theoretical Stress Concentration Factor
(Calculation completed in 00.004 seconds)
