What is anelasticity? (Select all that apply)
Select 2 correct answer(s) Question 25 options:
Time-dependent elastic behavior
Continuous deformation after loading and upon load release
Instantaneous elastic behavior
Purely elastic response without time dependence
Solution
To answer the question about anelasticity, let's break down the options provided:
-
Time-dependent elastic behavior: Anelasticity involves time-dependent behavior, meaning the material's response to stress or strain changes over time. This is a characteristic of anelastic materials.
-
Continuous deformation after loading and upon load release: Anelastic materials exhibit continuous deformation not only when a load is applied but also after the load is removed. This is another key feature of anelasticity.
-
Instantaneous elastic behavior: This describes a material that responds immediately to applied stress without any time-dependent effects. This is not characteristic of anelasticity.
-
Purely elastic response without time dependence: Purely elastic materials respond to stress without any time-dependent effects, which is contrary to the definition of anelasticity.
Based on the definitions and characteristics of anelasticity, the correct answers are:
- Time-dependent elastic behavior
- Continuous deformation after loading and upon load release
