Daniel_Melo's Postings

MicMac-FEA for Abaqus 6.11 is available for download at the download utility.

Submission date for HW#4 was postponed to January 26 since we have not received the new version of MicMac-FEA.

Effects of an Open Hole on the Biaxial Strengths of Composite Laminates.
Yuanchen Huang, Sung K. Ha, Jun Koyanagi, Jose Daniel D. Melo, Hisashi Kumazawa and Ippei Susuki.

In response to the question raised in the presentation about Materials and Processing, Prof. Miravete informed that the electrical conductivity of carbon fibers ranges from 500 - 20,000 (ohm-cm)-1.

These are the most relevant references for the presentation on fibers, matrices and manufacturing:

• S. W. Tsai, Strength & Life of Composites, Stanford University, 2009

1. Is a special process used to remove the reusable vacuum bags from the cured part to ensure the bags are not damaged, or are they sufficiently robust to allow them to be removed by hand?

We have uploaded MicMac-Hole for Office 2003. The file name is MicMac-Hole_2003_v205.xls

If your computer downloads MicMac-Hole as a zip file, please rename the zip file and add the extension .xlsm. You will need Excel 2007 with macros enabled to open the file.

Please send your homework to cdw.homework@gmail.com on Mondays, before 8:00 am (PT).

In response to requests received from some participants, we have postponed the deadline for submission of the second homework to Tuesday, Aug 3rd, before 8 AM (PDT).

A file with the homework assigned to be submitted Monday, Aug 2nd, is available in the folder "Homework".

A compressed (Zipped) folder is available for downloading the files related to the presentation on Full-Field Optical Measurement Systems.

For those interested in the effects of fiber arrangement on properties of UD composites, we recommend reading the following papers:

We have uploaded new versions of MMFatigue_v1.0 and SMM+v150_P_CDT7. These versions will fix the installation problems.

Question from Armando Mete: “Could you please provide Elastic/Strength properties for AS4/3601-6, IM6/3501-6 used for the Abaqus Umat-MMF Examples?

Question #1: From Fulya Aktas: "Do you do any surface treatment to bind CNTs to resin?"
Answer: "In our research work we have used MWCNTs and have not applied any surface treatment."

We have uploaded records from previous presentations by Prof. Antonio Miravete with better sound quality.

These are the references for 3-D Textile Reinforcement suggested by Prof. Antonio Miravete.

In case you have problems to run MicMac-Hole you probably need to load Excel add-ins. Please do the following:

1. Open Excel.
2. Click the Microsoft Office Button and then click Excel Options.

Executable versions of GenLam and Lamrank are now available in the download utility.
