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

Inventor Stress Analysis performs linear static FEA, calculating stress distribution, displacement, and safety factors under applied loads and constraints.

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

Von Mises stress combines all stress components into a single equivalent value that can be compared to the material yield strength to predict yielding.

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

Mesh refinement increases element density in areas of interest, improving result accuracy particularly around stress concentrations, at the expense of longer solve times.

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

Boundary conditions include both constraints (how the part is held) and loads (forces, pressures, moments applied) that define the analysis scenario.

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

A safety factor below 1.0 means the predicted stress exceeds the material's yield strength in that region, indicating the design may fail under the applied loads.
