Hi,

I would like to add composite material to the library. All I know about material in the attachment. I know adding some properties but this material have a lot of qualifications. So I don't know how to define all of those qualifications to the Material Properties. I am planning to do Static Structural and Steady-State Thermal analysis. I started learn ANSYS not long time. Your help will save me. Thank you for your time and consideration in advance.

Hi,

I believe that you are going to use Workbench and Mechanical, and thus you can find plenty of tutorails on Youtube.But I advise you to have a look into this AIC:

https://courses.ansys.com/index.php/courses/high-resolution-fe-model-of-bone/lessons/physics-setup-lesson-5-14/topic/1-create-material/

There will be a step by step methodology and some application examples. The most difficult part is to make sure, you don't miss a property for your further analysis.

A good starting point is to have a look into reference materials database provided by Ansys Granta. if you have an access. See here for more details:

https://www.ansys.com/products/materials (EduPack for education, Selector and MI for research)

You'll find as well other discussions on the forum about this topic: https://forum.ansys.com/forums/topic/adding-material-library/

And finally you can create your own composite materials with estimated properties using analytical tool (Synthesizer of Granta EduPack) or numerical tool (Material Designer), here for more details:

Hi David,

Thank you for your answer and time. But I am still confused about  my question.

Let me ask my question in this way; I have Mechanical properties of material and we can see those properties in this photo. 

Lets think like that, it is not composit material and I have to define those properties. I dont know how to meet all those properties in the material toolbox in ANSYS.

For example, I defined Density ( under the title ''Physical Properties'' ) and also I found how to define Tensile Yield Strength, Compressive Yield Strength ( under the title ''Strength'' )'. You can see below.

But the rest of properties such a  flexural strenght or modul of elasticity in flexion under which title i can find and define them.

It can happen that you don’t have a perfect match between the property name you have on the reference document/datasheet and the property name in Ansys (for example modulus of elasticity in flexion… maybe you could use the corresponding value for ‘Elastic modulus’ or ‘Young’s modulus’ in the section Linear Elastic). In this case it is a matter of definition, ontologies…and assumptions. Elastic properties in flexion can be very near elastic properties in tension if the material is isotrop for example.

It can happen as well that a specific property doesn’t exist in our list of material properties, and then you don’t use it, you try to use the ‘Custom Material Models’ or you can use Ansys MAPDL to create a user defined material behaviour: https://www.ansys.com/blog/what-is-apdl

Hope this can help.

Hi David,

Thank you for your answer. Everything is clear now.
