Question 1.
What is verification in the context of FEA?
Show hintHide hint
Think about what it means for a model to work properly.
Question 2.
Define validation as it pertains to engineering models.
Show hintHide hint
Consider how models relate to actual physical systems.
3Question 3.
What is the primary goal of verification in finite element analysis?
- To ensure results match experimental data
- To confirm models solve equations correctly
- To establish project milestones
Show hintHide hint
Think about what it means for a model to be accurate.
4Question 4.
True or False: Validation ensures a model produces results that are not influenced by the mesh size used in the simulation.
- True
- False
Show hintHide hint
Consider the differences between validation and verification.
Question 5.
A mechanical engineer is tasked with designing a new bridge. They have run simulations using FEA but have not performed a mesh independence study. What risks might this pose to the bridge's safety?
Show hintHide hint
Consider how mesh size can influence the accuracy of model predictions.
Question 6.
After testing a bridge design with FEA, an engineer finds their model's predictions differ significantly from measurements taken from a physical prototype. What steps should the engineer take next?
Show hintHide hint
Think about what factors could differ between simulation and reality.
