Mechanics of Structure Genome 

25 October | 1300–1430 hrs EDT

The abstract submission to the bi-annual AIAA Integrated Computational Materials Engineering (ICME) Prize) has been extended to August 24. The best project will be selected and honored at 2020 SciTech conference along with $1500 cash award. To participate, you need to submit a description of your project which will be reviewed by the ICME prize committee.

Co-sponsored by cdmHUB, NASA, and Rolls-Royce, the bi-annual AIAA Integrated Computational Materials Engineering (ICME) Prize) is open for submission. The best project will be selected and honored at SciTech conference. To participate, you need to submit a description of your project by June 29, 2018, which will be reviewed by the ICME prize committee. More details can be found at https://www.aiaa.org/icme/. If you are interested in submitting, please let me know. 

I will give a workshop on How to use cdmHUB as a Cloud Collaboratory for Composites Design and Manufacturing on The Conference on Advancing Analysis & Simulation in Engineering, June 5-7, Cleveland, Ohio. Details can be found at https://www.nafems.org/2018/americas/training/. 

Inspired by the discussion with Mike Ciavarella on http://imechanica.org/node/22012, I am thinking about a journal with the following attributes:

Dear Colleagues, if you are interested in the state-of-the-art R&D in composite materials, you might want to attend the American Society for Composites Anuual Meeting at Purdue (10/22-25, 2017). The registeration is open at https://cdmhub.org/groups/asc2017/registration

Purdue Composites Manufacturing & Simulation Center is looking for outstanding candidates to fill multiple faculty positions at the level of Full, Associate and Assitant Professor in composites manufacturing & simulation. Please check https://cdmhub.org/explore/newsletter for mroe details. 

Dear Imechanicians, I hope this turns out to be useful for some of you who are interested in sharing their computer codes. We are working on a free platform, cdmHUB.org, to allow users to quickly turn your scripts into Apps connected with HPC power in the cloud. Currently, the system can easily handle Linux or Windows executables. We are developing new functionalities so that other typical scripts such as Abaqus UMATs, Python scripts, matlab scripts can also be disseminated as launchable Apps in cloud.

Dear Fellow mechanicians, if your work is related with composites, you might want to consider presending your work on the American Society for Composites Annual Conference to be held on Purdue campus. The abstract is due this Friday (Feb. 17).

To motivate students to attend the conference, ASC 2017 offers up to 20 travel scholarships including free registration and travel expenses up to $500. The top six will also receive additional cash prizes. Details can be found at https://cdmhub.org/groups/asc2017/scholarship. Professors, please encourage your students to apply. The abstract due date is Feb. 17.  More details about the conference can be found at https://cdmhub.org/groups/asc2017.

We are delighted to invite you to attend the American Society for Composites Annual Technical Conference which will be held on the campus of Purdue University, Oct. 23-25, 2017. The conference website is: https://cdmhub.org/groups/asc2017. 

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.

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.

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.

Purdue will host the 32nd American Society for Composites (ASC) Annual Technical Conference. This conference convene composites researchers from around the world to interact with industry, government and academia, fostering collaborations among all stake holders in the composites community. More detailed information can be found at the conference website at https://cdmhub.org/groups/asc2017.

Join us for the 2016 Composites Simulation Workshop at Purdue University. Learn about and engage with world-class researchers and industry experts in multi-scale composites modeling. Interact with state-of-the-art composites simulation software; hear expert, cutting-edge advances in strength and lifecycle prediction modeling. Experience composites 3D printing and advances in composites manufacturing modeling for high-rate automotive applications.

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.

Dear Imechanicians,

cdmHUB has completed the level I micromechanics simulation challenge. Several micromechanics methods/tools including both commercially available tools such as  Altair MDS, ESI VPS, Digimat, SwiftComp and research codes such as MAC/GMC/HFGMC and FVDAM, are used to analyze six typical 2D/3D microstructures.

The aim of this post is to introduce the mechanics of structure genome (MSG) as a possible unified approach for constitutive modeling of structures and materials. Because this discussion relates with structural mechanics and micromechanics, two familiar topics which have been studied by many, it is difficult to cite all the relevant references in a blog post without missing important ones. Thus, I only share some general understanding of relevant topics which are available from typical textbooks.
