- In axial tension, the ratio of axial stress to strain is always constant( ).
- According to Maximum Principal Stress theory (also known as Rankine's theory of failure), elastic failure occurs ( ) A: when the minor principal stress is equal to the elastic limits value in a simple tension test B: when the greatest principal stress reaches the elastic limit value in simple tension test C: when the greatest principal stress is equal to the stress corresponding to the upper yield limit in a tension test D: none of the above
