Impact strength is a material property that describes its ability to withstand a sudden applied force or shock without fracturing or breaking. It measures how much energy a material can absorb during a high-speed impact before it fails. This property is used in engineering and material science, especially for applications where materials face dynamic loads, such as in automotive parts, protective gear, or construction components.

\( IS \;=\; \dfrac{ E_a }{ A_c }\) (Impact Strength) \( E_a \;=\; IS \cdot A_c \) \( A_c \;=\; \dfrac{ E_a }{ IS }\) |

| Symbol | English | Metric |
| \( IS \) = Impact Strength | \(ft-lbf\;/\;in^2\) | \(J\;/\;mm^2\) |
| \( E_a \) = Energy Absorbed | \(ft-lbf\) | \(J\) |
| \( A_c \) = Area Cross-section | \(in^2\) | \(mm^2\) |
