How To Change Material On Solidworks

Changing the material of a part in SolidWorks is a fundamental skill, essential for accurate simulation, analysis, and documentation. The material properties directly influence factors such as weight, strength, thermal behavior, and cost. Whether you are a seasoned engineer or a student exploring CAD, mastering this process will significantly enhance your design capabilities.

Understanding Material Properties in SolidWorks

SolidWorks leverages material properties to perform simulations and calculations, providing insights into the structural integrity and performance of your designs. These properties include:

• Density: Mass per unit volume, affecting the overall weight.
• Elastic Modulus (Young's Modulus): A measure of stiffness, indicating how much a material will deform under stress.
• Poisson's Ratio: The ratio of transverse strain to axial strain, describing how a material deforms in directions perpendicular to the applied force.
• Shear Modulus: A measure of a material's resistance to shear stress.
• Thermal Expansion Coefficient: The extent to which a material expands or contracts with changes in temperature.
• Tensile Strength: The maximum stress a material can withstand before breaking under tension.
• Yield Strength: The stress at which a material begins to deform permanently.

By assigning the correct material, you ensure that SolidWorks uses realistic data for calculations, resulting in more accurate simulations and reliable design decisions.

Step-by-Step Guide to Changing Material in SolidWorks

• Evaluate Properties: Use the "Evaluate" tab in the CommandManager to check material properties such as density and mass. Go to Evaluate > Mass Properties. This will confirm that the correct material properties are being used for calculations.

7. Changing Material Appearance (Optional):

Applying a material changes its physical properties, but you can also customize its visual appearance.

• Right-click on the part in the graphics area or Feature Tree and select "Appearance."
• Choose a color, texture, or surface finish. SolidWorks offers a wide range of appearances to choose from.
• You can also apply appearances at the feature level. This allows you to have different parts of the same body appear differently.

Applying Materials to Multiple Parts in an Assembly

When working with assemblies, you may need to apply materials to multiple parts. Here are a few methods to do this efficiently:

1. Applying Material to Individual Components:

• Follow the steps outlined above for each individual component in the assembly.
• This is the most straightforward method, but it can be time-consuming for large assemblies.

2. Applying Material to Multiple Selected Components:

• Select multiple components in the Feature Tree by holding down the "Ctrl" key and clicking on each part.
• Right-click on any of the selected parts and select "Material" > "Edit Material."
• Choose the desired material and click "Apply" and "Close." The material will be applied to all selected components.

3. Using Configurations:

Configurations allow you to create different versions of a part or assembly, each with different properties, including material.

• Create a New Configuration: In the ConfigurationManager tab (next to the Feature Tree), right-click on the part name and select "Add Configuration." Give the configuration a descriptive name (e.g., "Aluminum," "Steel").
• Assign Material to the Configuration: Activate the new configuration by double-clicking on it. Then, follow the steps to apply the desired material.
• Repeat for Other Configurations: Create additional configurations as needed, each with a different material assigned.
• Switch Between Configurations: You can easily switch between configurations to explore different material options.

4. Using Design Tables:

Design tables are Excel spreadsheets embedded in SolidWorks that allow you to control various parameters of a part or assembly, including material.

• Insert a Design Table: Go to Insert > Tables > Design Table.
• Select the "Material" parameter to control. SolidWorks will automatically create a column for the material property in the Excel spreadsheet.
• Enter the different material options in the spreadsheet. Each row represents a different configuration.
• SolidWorks will automatically create configurations based on the data in the design table.
• When you modify the values in the Design Table, the assembly will be updated automatically.

Creating and Editing Custom Materials

SolidWorks' default material library is extensive, but you may need to create custom materials with specific properties for your application. Here's how:

1. Open the Material Dialog Box:

• Use any of the methods described earlier to open the material dialog box (e.g., right-click on a part in the Feature Tree and select "Material" > "Edit Material").

2. Create a New Material:

• In the material dialog box, right-click on a category (e.g., "Custom Materials") and select "New Library." Give the new library a name (e.g., "My Materials").
• Right-click on the new library and select "New Category." Give the category a name (e.g., "Special Alloys").
• Right-click on the new category and select "New Material." Give the material a name (e.g., "High-Strength Alloy X").

3. Enter Material Properties:

• The right pane of the material dialog box will display the properties of the new material.
• General: Enter basic information about the material, such as its description, source, and notes.
• Material Properties: This is where you define the critical material properties that SolidWorks will use for calculations.
