Understanding Material Failure

The video tutorial discusses two types of material failure: brittle failure and plastic deformation. Brittle failure occurs suddenly without warning, like when glass shatters. In contrast, plastic deformation involves gradual stretching until the material breaks, similar to overloading a shopping bag. The tutorial highlights the differences between these failure types and encourages further exploration of fracture mechanics.

What type of failure occurs when a material breaks suddenly without warning?

• Ductile failure

• Elastic deformation

• Plastic deformation

• Brittle failure

What is an example of plastic deformation?

• A glass shattering

• A metal rod bending

• A balloon popping

• A ceramic plate cracking

What happens to a material undergoing plastic deformation?

• It breaks instantly

• It stretches and then breaks

• It melts

• It evaporates

Which type of failure involves no prior warning before breaking?

• Plastic deformation

• Brittle failure

• Elastic deformation

• Ductile failure

What is a key difference between brittle failure and plastic deformation?

• Plastic deformation happens instantly

• Brittle failure occurs without warning

• Brittle failure involves stretching

• Plastic deformation does not involve any stretching
