Dear Mithilesh,

If you would like to design different RVE for textile composites, there is a free software developed by Nottingham University called TexGen. This software helps you design different RVE for 2D and 3D textiles and predict the homogenized elastic material properties. It can also export the RVE as ABAQUS input file. Please have a read through the software platform to get familiarized with it.

I did some work with TexGen for 3D woven composites but using UMAT not VUMAT. You can check the paper: "Micro-mechanics based damage mechanics for 3D orthogonal woven composites: Experiment and numerical modelling"

However, this will not solve your issue with running the impact simulation with ABAQUS because you will still need the VUMAT to run such simulation if you need to define your own damage constitutive behavior. If you will simulate the material with its effective homogenized properties obtained from TexGen and use one of the damage models in ABAQUS, so you can find many videos on the internet giving examples such as this one: https://www.youtube.com/watch?v=7PrwggZTkWs

I hope you find this useful.

Dear Mithilesh,

It's not entirely clear to me if you mean 2D and 3D weaves or 2D and 3D analysis of (2D) weaves. No impact simulation of composite materials with woven reinforcement is trivial but for ones with 2D reinforcement there is at least a lot of work presented in the literature. For 3D-woven reinforcement there is no quick-fix to this I'm afraid. There are considerable differences between different 3D textiles and the material properties vary considerably also within a single textile, due to the complexity of its architecture. There is an increasing number of works being published on modelling of 3D-reinforced composite (some of which I've been involved in), but from my viewpoint there are no reliable methods or models for impact simulation around yet.

Best regards,

Stefan
