# Analysis Lesson 3: SOLIDWORKS and 3DEXPERIENCE Simulation Linear Structural Validation Part 2

After teaching 1000’s of students and writing about SOLIDWORKS and SOLIDWORKS Simulation for over 25 years, David Planchard, emeritus WPI, is exploring 3DEXPERIENCE Simulation and the Abaqus solver.  Through the SOLIDWORKS and 3DEXPERIENCE Simulation Lesson series, David helps educators understand 3DEXPERIENCE Simulation fundamentals through simple examples and industry practices.

I ask my students, what is the objective of Structural Design? I tell them that Structural Design simply ensures that a component will not fail when it is subjected to the loads it was designed to withstand. An understanding of Stress limits is required. Strain limits are important, but will not be addressed in this lesson.

In the previous, Analysis Lesson 2 SolidWorks and 3DEXPERIENCE Simulation Linear Structural Validation Part 1, we learned the proper workflow to upload a SOLIDWORKS part to the 3DEXPERIENCE platform and perform a Linear Structural Simulation study using the Abaqus solver. The Linear Structural Validation App was launched from the SOLIDWORKS Task Pane.

Simulation study solver preferences were addressed. Study conditions were applied: (Mesh type, Material, Fixed Displacement Restraint and Load using the Action bar and the Assistant dialog box. Three contour plots were created: Von Mises Stress, Displacement, and Factor of Safety (FOS). The Simulation Study results were analyzed and saved to a Collaborative space in a Bookmark.

In this lesson, locate the Linear Structural Simulation study in your Collaborative space with the 3DSpace widget. Launch the Linear Structural Validation App.

Modify the results storage from the server on the platform to your computer. Discover the default storage folder location on a local Window’s machine.

Modify the original load from 13300N to 23300N. Create new Simulation study contour plots. Review the plots to interpret the results.

Modify the original material from Alloy Steel to 6061 Alloy. Create new Simulation study contour plots. Review the plots to interpret the results.

Play and save a Simulation contour plot animation. Save the animation. Compare results of four Simulation study contour plots (Von Mises Stress, Factor of Safety, Reaction Force and Displacement).

Create a Simulation report. Save the report. View various Simulation help options.

Before we start, there are a few items that you need to know.

In this lesson, use your default Collaborative space. An internet connection is required. A 3DEXPERIENCE ID is required.

The Simulation lesson provides a foundation to users who are new to using simulation to solve real-word engineering and design problems. A Solid body is used. You should have a basic understanding of Stress and Finite Element Method (FEM).

## Factory of Safety Plot

Review the Factor of Safety (FOS) contour plot to identify the critical regions of the model. The FOS plot displays how close a material is to yielding. The Factor of Safety is calculated by dividing the material’s Proof (Yield) Strength by the Allowable stress.

The FOS plot has a maximum limit of 2 by default. Regions of the model with a FOS larger   than 2 are shown in gray.

The old Factor of Safety (FOS) range: Min: .562 – Max: 829.

The new Factor of Safety (FOS) range: Min: .321 – Max 473.

## Von Mises Stress Plot

Display the Von Mises Stress contour plot with the new load (23300N).

Verify that the Von Mises stresses do not exceed the material’s yield strength. For most metals, the yield strength is defined as the stress point at 0.2% strain offset. For Alloy Steel this is (6.204 × 108N/m2).The maximum Von Mises stress (1.93 × 109N/m2) is above the material’s yield strength of (6.204 × 108N/m2).

Below is the Von Mises Stress contour plot with the original load (13300N).

Finite Element Analysis (FEA) has been used for decades to help designers and engineers understand how parts and the materials they are made from behave in real life. In most cases, the analyst is looking for stresses that exceed yield or strain higher than the failure rating of the material.

Most parts are incorporated into subassemblies. Other important factors for designs are cost and overall weight of the final assembly.

In the next section, modify (lower) the overall mass of the material and rerun the Simulations study to evaluate Structural integrity.

## Review Results

Display the Von Mises Stress contour plot with the new material (6061 Alloy).

Verify that the Von Mises stresses do not exceed the material’s yield strength. For most metals, the yield strength is defined as the stress point at 0.2% strain offset. For 6061 Alloy this is (5.157 × 107N/m2).The maximum Von Mises stress (1.92 × 109N/m2) is above the material’s yield strength of (5.157 × 107N/m2).

The mass of the part is 849.65 grams.

Below is the Von Mises Stress contour plot with the old material (Alloy Steel).

Verify that the Von Mises stresses do not exceed the material’s yield strength. For most metals, the yield strength is defined as the stress point at 0.2% strain offset. For Alloy Steel this is (6.204 × 108N/m2).The maximum Von Mises stress (1.93 × 109N/m2) is above the material’s yield strength of (6.204 × 108N/m2).

The mass of the part is 2423.08 grams.

Display the Factor of Safety (FOS) contour plot.

Regions of the model with a FOS less than 1 develop stresses above the material’s yield strength under the current loading conditions.

The smallest factors of safety occur in the localized regions where the highest Von Mises stresses occur.

The range is between 0.0287 and 62.9. This plot is concerning due to the amount of area with a FOS below 1.

Further investigation of material and or the design would be highly recommended.
