Material Properties 2022

What is a plastic material?

• Change their shape when under a load, but return to their original shape when the load is removed.

• Change their shape when under a load, but they remain permanently deformed when the load is removed.

• Break or crumble rather than deform under a load.

• Can easily be shaped by hammering or rolling, and they keep their new shape. Some materials can be made more malleable by heating.

What is an elastic material?

• Change their shape when under a load, but return to their original shape when the load is removed.

• Change their shape when under a load, but they remain permanently deformed when the load is removed.

• Break or crumble rather than deform under a load.

• Can easily be shaped by hammering or rolling, and they keep their new shape. Some materials can be made more malleable by heating.

What is a brittle material?

• Change their shape when under a load, but return to their original shape when the load is removed.

• Change their shape when under a load, but they remain permanently deformed when the load is removed.

Failure Mode is:

• Where in the object failure occurred

• What physically happened in the failure

• The aspect of design, defect, or load that lead to the failure

• The way the object failed—for example, suddenly or gradually
