Stress Amplitude Solution

STEP 0: Pre-Calculation Summary

Formula Used

Stress Amplitude = (Maximum Stress at Crack Tip-Minimum Stress)/2
σ_a = (σ_max-σ_min)/2
This formula uses 3 Variables

Variables Used

Stress Amplitude - (Measured in Pascal) - Stress amplitude is one half of the range of stress of a stress cycle in fatigue.
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.
Minimum Stress - (Measured in Pascal) - Minimum Stress is defined as the minimum stress that is induced or applied to the object.

STEP 1: Convert Input(s) to Base Unit

Maximum Stress at Crack Tip: 62.43 Newton per Square Meter --> 62.43 Pascal (Check conversion here)
Minimum Stress: 106.3 Newton per Square Meter --> 106.3 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

σ_a = (σ_max-σ_min)/2 --> (62.43-106.3)/2

Evaluating ... ...

σ_a = -21.935

STEP 3: Convert Result to Output's Unit

-21.935 Pascal -->-21.935 Newton per Square Meter (Check conversion here)

FINAL ANSWER

-21.935 Newton per Square Meter <-- Stress Amplitude

< Normal Stress Calculators

Normal Stress for Principal Planes at Angle of 0 Degrees given Major and Minor Tensile Stress

Go Normal Stress = (Major Tensile Stress+Minor Tensile Stress)/2+(Major Tensile Stress-Minor Tensile Stress)/2

Normal Stress for Principal Planes when Planes are at Angle of 0 Degree

Go Normal Stress = (Major Tensile Stress+Minor Tensile Stress)/2+(Major Tensile Stress-Minor Tensile Stress)/2

Normal Stress for Principal Planes at Angle of 90 degrees

Go Normal Stress = (Major Tensile Stress+Minor Tensile Stress)/2-(Major Tensile Stress-Minor Tensile Stress)/2

Normal Stress across Oblique Section

Go Normal Stress = Stress in Bar*(cos(Angle Made By Oblique Section With Normal))^2

Stress Amplitude Formula

Stress Amplitude = (Maximum Stress at Crack Tip-Minimum Stress)/2
σ_a = (σ_max-σ_min)/2

Define stress amplitude?.

One-half of the range of fluctuating stress developed in a specimen in a fatigue test. Stress amplitude often is used to construct an S-N diagram. The Alternating Stress is the measure of the forces a component is subjected to over a time limit. These would vary from low (zero) to high positive or in some cases negative - imagine a door being opened & closed multiple times.

How to Calculate Stress Amplitude?

Stress Amplitude calculator uses Stress Amplitude = (Maximum Stress at Crack Tip-Minimum Stress)/2 to calculate the Stress Amplitude, Stress Amplitude formula is defined as a measure of the variation in stress from the average stress, providing a way to quantify the fluctuating stress in a material or structure, which is critical in understanding its fatigue behavior and potential for failure. Stress Amplitude is denoted by σ_a symbol.

How to calculate Stress Amplitude using this online calculator? To use this online calculator for Stress Amplitude, enter Maximum Stress at Crack Tip (σ_max) & Minimum Stress (σ_min) and hit the calculate button. Here is how the Stress Amplitude calculation can be explained with given input values -> -21.935 = (62.43-106.3)/2.
