International Conference on Composites Materials (ICCM-21), Xi'an, China, August 20-25, 2017

Submitted by Wenbin Yu on

The 21st International Conference on Composites Materials (ICCM-21) will be held in Xi'an, China, August 20-25, 2017. ICCM, the most premier conference in the field of composite materials, aims at encouraging the exchange of the researches and insights from scientists and scholars, and promoting research, development and use of composite material and structures. You are welcome to  submit to Track 2.2 Multiscale Modeling of Structures to share your great ideas on multiscale modeling.

Textile Composite Property Calculator in the Cloud

Submitted by Wenbin Yu on

I hope this information will be helpful for some researchers. We recently integrated TexGen with SwiftComp, called TexGen4SC, to provide a very easy app to compute thermoelastic properties for textile composites for all the types of woven microstructures which can be generated by TexGen. This tool can achieve RVE analysis accuracy with a very small fraction of its computing time. This tool can respect the finite thickness of a woven fabric. It can be freely launched on any device (smart phones, ipads, etc) connected to Internet.

A Better Alternative to RVE Analysis

Submitted by Wenbin Yu on

RVE analysis is popular for computational homogenization. It can be used independently for virtual testing or as a module for multiscale modeling. Its popularity is mainly due to the maturity and acceptance of commercial finite element software. RVE analysis usually requires a 3D domain to obtain 3D properties and local fields. If a 2D RVE is used, only 2D properties and local fields are obtained. To obtain the complete set of properties, multiple analysis is needed. For example, to obtain the complete stiffness matrix, six 3D RVE analyses are needed.

cdmHUb Hands-on Workshop for Composites Learning, Teaching and Research in the Cloud

Submitted by Wenbin Yu on

Join us at the American Society for Composites 31st Technical Conference (Williamsburg, VA) for a hands-on workshop, on September 18, from 7:00–9:00pm, on how to use cdmHUB.org for composites learning, teaching, and research in the cloud. This workshop features an overview of the cdmHUB cyberinfrastructure, and how to use cdmHUB for learning, teaching, and research. We will demonstrate how to use cdmHUB to develop and launch composites simulation tools.

RVE analysis without BCs and periodic mesh requirements

Submitted by Wenbin Yu on

RVE analysis becomes a routine exercise in material modeling. Usually it is carried out using finite element codes such as ABAQUS or ANSYS. The main thing one should pay attention is to applying the right boundary conditions. It is settled that periodic boundary conditions are the preferred boundary conditions to be applied. The BCs are that u_i-\epsilon_{ij}x_j should be equal on the corresponding edges. This type of boundary conditions can be applied using coupled equations constraints. This requires that one creates a mesh with corresponding nodes on periodic edges.
