Trouble in running LAMRANK tool

Abishek's picture

I extracted all files into a folder and I tried running the LAMRANK exe file from the EXEC folder and I get an error message "The parameter is incorrect".

Is there a version of Mic-Mac FEA for Nastran?

Brett_Peterson's picture

There are comments in the forum relating to a version of Mic-Mac FEA for Nastran. Does this still exist and if so how do I get a copy of it?


Strength ratio determination

Sanita_Zike's picture

How the strength ratio - R/FPF - is determined in MicMac? What values correspond to R?

Homework deadline postponed

Fiber/matrix interfacial shear strength testing--Antonio's comment

tom.demint's picture

Yesterday Antonio mentioned I think three ways to test the fiber/matrix interfacial shear strength. Antonio can you post these and some references please?


Stiffness of the Laminate

Hi all,

Does any one know how to obtain [A], [B] and [D] matrices in ABAQUS?


Multilaminate part

Hi all,

I am looking for advice.

I have a part where based on MicMac, I would need two different ply-angle laminates:

Dear Steve, Daniel, and all the presenters,

HyBlade and MicMac Beam are fantastic

Naresh_Sharma's picture

Thank you all, Prof Tsai, Prof Ha, and your team, for all the micmac's and especially these two products. After the ipost was loaded, I tried to play around with these tools and wow, they're superb. They will really make our work in the conceptual phase a cake walk.

As a pay-back, I'll try to add a generic airfoil capability in the tool and post it here when its ready. If anyone is interested in contributing, please feel free to chime in here or email me directly.

I'd suggest the following:
The plan is to first allow a generic airfoil to be defined. Then extract 2D lift/drag figures from XFoil add a lifting line theory to generate spanwise lift distribution. This will be fairly accurate in load generation. From this a model that could be scaled can be easily added to HyBlade like a template.

Pultrusion in using open bath

Naresh_Sharma's picture

As a manufacturing company located in Italy, we've been told by the environmental agency here that in a new operation, such as ours, they will not allow/license the manufacture of anything with open access to resin. Therefore, meeting the environmental requirements will far outweigh the costs involved in developing the same process using pultrusion dies with infusion of resin. Additionally, due to new VOC regulations any existing operation using such methods has a limited number of years to cease all high VOC type of activity in area's open to workers.

This points to the answer for ladder manufacture question and the nature of the information shared.

Is there HW 7, 8, or 9???

Joseph_Nelson's picture

Is there a homework 7, 8, or 9? On Monday Sung Ha said he had not prepared a homework set for 3D beams (HW 7) and then on yesterday Jeffery Fong only very briefly said that

Will MicMac FEA for Abaqus 6.11 be posted soon?

Joshua_Root's picture

I still can't get MicMac FEA to run properly. Even after chaning the visual basic code to the right batch file, it still won't run Abaqus. Will the updated version of MicMac FEA be posted soon?

Material Database

David_Rouison's picture

Is there any data available for E-Glass/Unsaturated Polyester (isophthalic) combination to use in MicMac? I have only found E-glass/Epoxy combinations to date. Thanks!

Has there been any update on MicMacFEA (to work with V6.11) and MicMacBeam (for the Java post-processor)?

Hello, has there been any update on MicMacFEA (to work with V6.11) and MicMacBeam (for the Java post-processor)?

Thank you.

LAMRANK issues

Doug.Hall's picture

I downloaded the file, saving it in a folder on my desktop. I extracted everything into a directory in that folder.

Carbon Frame Tubing Bonding

In building carbon bicycle frames we use the traditional tube to tube construction method.

Best software choice for analyzing round carbon bicycle frame tubing

John_Eggers's picture

As a new designer I just want to double check the following:

Is MicMac Lt appropriate for the analysis of round carbon bicycle tubing? Or should I use FEA?

Homework HW#4 postponed

Daniel_Melo's picture

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