Ductile, Brittle materials? Methods to identify them.

Question

Accepted Answer

Ductile materials can be stretched without breaking, while brittle materials break easily. Various tests can identify them.

Ductile materials include copper, aluminum, and steel. Brittle materials include glass and ceramics.
A tensile test can determine if a material is ductile or brittle. A ductile material will stretch before breaking, while a brittle material will break without stretching.
A Charpy impact test can also identify brittle materials. This test measures the amount of energy required to break a material.
Other tests include the Rockwell hardness test and the Brinell hardness test.
It's important to know the properties of materials to ensure they are used appropriately in various applications.
