Altering Material Properties Data for Simulation

Anonymous — Mon, 02 Jan 2017 21:13:43 GMT

Hello,

I am currently attempting to perform a static stress simulation on a model but the porcelain material that I have chosen does not contain any data for Young's modulus or yield strength which means that the simulation cannot be completed.

Is it possible to create a ceramics material with custom material properties or, alternatively, change the material properties of porcelain within Fusion 360?

Hi thompson766,

You can create a copy of the porcelain material (by adding it into your Favorites library) then modify the copy to your needs. This is done using the Manage Materials editor.

For a static stress simulation, you'll need to specify at least the density, Young's modulus, and Poisson's ratio. For the Safety Factor calculation of the ceramic brittle material, you'll want to base the Safety Factor calculation using the Ultimate Strength, rather than the (default) yield stress for a ductile material. You can use the selector pull-down in the Study Materials dialog in the Simulation workspace.

Google search gave a range in properties for porcelain, so having more precise material properties would be desired (of course). http://www.makeitfrom.com/material-properties/Engineering-Porcelain

I hope this helps! Please let us know if you have any additional questions, comments, or suggestions.

Hello,

Maybe you can help me as well.

I can not change the physical material properties that I need to change. Can you please give me a detailed step-by-step explanation for how I change the "Ultimate Tensile Strength"-values for a copied Material in favorites library? And/or is there a way to make a brand new physical material? I need Expanded Polyprophylene, have all the data for it, but cant fill it in anywhere...You would save my day, thanks already!!!

Hi autodesk,

1. Use the Manage Materials command in the Modify panel to bring up the Material Browser in the Model Workspace ( alternately, you can access the Manage Materials command from the Simulation workspace using the Manage Physcial Properties command in the Materials toolbar panel).

2. Choose a material that is similar to the custom one you want to create (double-click it or right-click -> Add to Favorites)

3. Now you are editing the copied material in your Favorites library -> activate the Physical tab -> expand the Strength pane -> edit the tensile strength property value
4. In Simulation, set the Study Material and use the Library selector drop-down and choose Favorites -> Choose the custom material

5. Expand the properties pane using the >> button and verify that the intended property values are displayed for the body's study material

I've attached a video that shows the steps as well.

Hope this helps!
