## 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:

- First, determine the minimum stress (GPa).
- The minimum stress (GPa) is given as: 400.

- Next, determine the maximum stress (GPa).
- The maximum stress (GPa) is provided as: 850.

- 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
