Mechanical Behavior of Ductile Materials - Strain Hardening

Answer the following questions.

  1. What is the value of flow stress at strain = 1?
  2. Which material parameter, K or n, has a larger effect on material strength?
  3. If the value of K is doubled, by how much does the flow stress change?
  4. If the value of n is halved, by how much does the flow stress change?

Answers can be obtained by studying the stress strain behavior shown on the plot below.
