Rodda's

Rodda’s law describes how the strength of certain materials, like brittle solids, decreases as their size increases. Essentially, smaller samples tend to be stronger and more resistant to breaking, while larger ones are more likely to fail under the same conditions. This is because flaws or weaknesses are less likely to be present in tiny samples, but become more common as the material’s size grows. The law helps engineers predict how materials will perform at different scales, ensuring safety and reliability in design, especially for applications involving ceramics, glass, and other brittle substances.
