Define longitudinal strain.
Think about how length changes when pressure is applied.
What does local strain refer to?
Consider different areas of a bar under a load.
What is the formula for longitudinal strain?
Remember the basic definition of strain.
True or False: Local strain and global strain refer to the same measurement of deformation.
Consider the definitions of both terms.
A bar of length 5 m undergoes a longitudinal strain of 0.01. What is the change in length?
Use the definition of strain to solve.
Given a complex structure subject to varying loads, describe how you would evaluate strains using the deformation gradient tensor.
