ACP Stress Analysis

Question 1

What type of analysis does Inventor Stress Analysis perform?

Accepted Answer

Linear static finite element analysis (FEA) to predict stress, displacement, and safety factor

Answer

Thermal cycling simulation

Answer

Fluid dynamics simulation

Answer

Electromagnetic field analysis

Question 2

What is the von Mises stress in Inventor Stress Analysis results?

Accepted Answer

A combined stress measure that predicts yielding under complex stress states

Answer

Maximum principal stress only

Answer

The average stress across the entire part

Answer

Stress at the center of gravity only

Question 3

Why is mesh refinement important in Inventor FEA?

Accepted Answer

Finer mesh in critical areas produces more accurate stress results at the cost of computation time

Answer

It makes the model look smoother

Answer

Mesh refinement is purely cosmetic

Answer

It reduces file size

Question 4

What are boundary conditions in Inventor Stress Analysis?

Accepted Answer

Constraints and loads applied to the model that define how it is supported and loaded

Answer

The physical dimensions of the part

Answer

Material property specifications

Answer

Display settings for results

Question 5

What does a safety factor below 1.0 indicate in Inventor Stress Analysis?

Accepted Answer

The stress exceeds the material yield strength, indicating likely failure

Answer

The design is adequate

Answer

The mesh needs refinement

Answer

The analysis has an error

Question 6

How does Inventor handle contact between parts in assembly stress analysis?

Accepted Answer

It detects contacting faces and applies bonded, sliding, or separation contact conditions

Answer

It ignores all contacts

Answer

Contacts are only simulated in motion studies

Answer

All parts are treated as a single body
