Fusion 360 Simulation and Analysis 1 — Questions and Answers
Question 1: What type of analysis does Fusion 360's Simulation workspace primarily perform?
- Finite Element Analysis (FEA) for structural stress and deformation (Correct answer)
- Computational Fluid Dynamics (CFD)
- Kinematic motion analysis
- Thermal radiation modeling
Correct answer: Finite Element Analysis (FEA) for structural stress and deformation
Fusion 360's built-in Simulation workspace uses FEA to calculate how parts deform, stress, and strain under applied loads.
Question 2: In Fusion 360 Simulation, what is a 'Constraint' used for?
- Defines how the model is supported or fixed in space during analysis (Correct answer)
- Applies loads to the model
- Assigns material properties
- Defines mesh density
Correct answer: Defines how the model is supported or fixed in space during analysis
Constraints (boundary conditions) restrict movement at specific surfaces or points, simulating how the part is held in real-world use.
Question 3: What does 'Von Mises Stress' show in a Fusion 360 FEA result?
- The equivalent stress at each point for comparing against material yield strength (Correct answer)
- The maximum principal stress only
- The temperature distribution
- The displacement magnitude
Correct answer: The equivalent stress at each point for comparing against material yield strength
Von Mises stress combines all stress components into a single equivalent value for easy comparison to a material's yield strength to determine if it will fail.
Question 4: What is a 'Safety Factor' in Fusion 360 Simulation results?
- The ratio of material yield strength to the computed stress, indicating how close a part is to failure (Correct answer)
- The percentage of material used relative to stock
- The number of FEA mesh elements
- The simulation convergence tolerance
Correct answer: The ratio of material yield strength to the computed stress, indicating how close a part is to failure
Safety factor equals the material yield strength divided by the local Von Mises stress, showing how much extra strength margin exists before failure.
Question 5: What does 'Mesh' refer to in Fusion 360 Simulation?
- The network of small geometric elements used to divide the model for FEA calculations (Correct answer)
- The surface finish appearance of the part
- The assembly connection pattern
- The G-code toolpath grid
Correct answer: The network of small geometric elements used to divide the model for FEA calculations
The mesh is the discretized representation of the model divided into tetrahedral or hexahedral elements where stress calculations are performed.
Question 6: In Fusion 360 Simulation, what is a 'Structural Load'?
- A force, pressure, or moment applied to the model to simulate real-world forces (Correct answer)
- A material density property
- A boundary condition restraining movement
- A thermal input to the model
Correct answer: A force, pressure, or moment applied to the model to simulate real-world forces
Structural loads (forces, pressures, moments) are applied to model surfaces or edges to replicate real-world forces the part experiences.
