Show hintHide hint
Think about the body's original shape.
Question 2.
What is the displacement vector?
Show hintHide hint
Consider how points shift due to deformation.
3Question 3.
What represents the state of a body before deformation?
- Reference Configuration
- Deformed Configuration
- Displacement Vector
Show hintHide hint
Remember this is the starting point before forces are applied.
4Question 4.

- True
- False

Question 5.
Consider a cube of material undergoing uniform deformation. If the original position vector is X and the deformed position is x, derive the relation between the deformation gradient tensor F and the strain at each point.
Show hintHide hint
Apply chain rule and consider how coordinates depend on displacements.
Question 6.
Design a 3D simulation of a cantilever beam subjected to loading. Discuss how you would represent the reference and deformed configurations in the simulation.
Show hintHide hint
Think about computational models and how they represent physical changes.
