Enter the minimum stress (GPa) and the maximum stress (GPa) into the Stress Ratio Calculator. The calculator will evaluate and display the Stress Ratio.

## Stress Ratio Formula

The following formula is used to calculate the Stress Ratio.

STR = MINS / MAXS * 100

• Where STR is the Stress Ratio (%)
• MINS is the minimum stress (GPa)
• MAXS is the maximum stress (GPa)

## How to Calculate Stress Ratio?

The following example problems outline how to calculate Stress Ratio.

Example Problem #1:

1. First, determine the minimum stress (GPa).
• The minimum stress (GPa) is given as: 400.
2. Next, determine the maximum stress (GPa).
• The maximum stress (GPa) is provided as: 850.
3. Finally, calculate the Stress Ratio using the equation above:

STR = MINS / MAXS * 100

The values given above are inserted into the equation below and the solution is calculated:

STR = 400 / 850 * 100 = 47.058 (%)

Example Problem #2:

For this problem, the variables required are provided below:

minimum stress (GPa) = 600

maximum stress (GPa) = 1500
