The formula to calculate the Reduction of Area (ROA) is:
\[ ROA = \frac{TR}{IA} \times 100 \]
Where:
Reduction of Area (ROA) is a measure of the decrease in cross-sectional area of a material, typically used in materials science and engineering to assess ductility and toughness. It is calculated by dividing the total reduction in area by the initial area, then multiplying by 100 to get a percentage.
Let's say the initial area (IA) is 50 square units and the total reduction (TR) is 10 square units. Using the formula:
\[ ROA = \frac{10}{50} \times 100 = 20\% \]
So, the reduction of area (ROA) is 20%.
