Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

Define plastic behavior.

💡 Hint: Think about what happens when materials are over-stressed.

Question 2

Easy

What is the yield point in materials?

💡 Hint: It's the transition from elastic to plastic behavior.

Question 1

What happens to a material after it surpasses its yield point?

  • It returns to its original shape
  • It deforms permanently
  • It crumbles

💡 Hint: Think about the distinction between elastic and plastic behavior.

Question 2

Elastic materials can revert to their original shape after stress is removed.

  • True
  • False

💡 Hint: Recall what happens when you stretch a rubber band.

Challenge Problems

Push your limits with challenges.

Question 1

A structural beam made of a ductile material is subjected to increasing loads. Analyze at which load condition it transitions from elastic to plastic behavior and what consequences that may have in design.

💡 Hint: Focus on how yield point values are used in engineering safety factors.

Question 2

During a test, a glass panel is subjected to a static load beyond its elastic limit. What can be expected in terms of stress distribution and failure? Discuss the implications.

💡 Hint: Remember the stress-strain behavior of brittle materials during excessive loading.
