Analyzing & Optimizing Composite Layups / rectangular beam-discrete laminates-cross sectional linking options issue

« Last post by eugenio on Yesterday at 01:17:37 AM »

hello,

I'm trying to optimize a composite rectangular beam but when I pass from effective laminates to discrete laminates and perform the sizing it turns out a beam with same thickness for all walls (top, side and bottom).
All Cross-sectional linking options are deactivated, also sizing with effective laminates turned out different wall thicknesses.
I also tried to perform the sizing with metallic (isotropic) material and the results, as expected, were similar to effective laminates ( different wall thicknesses).
what is the problem?

thanks,
Eugenio

Yes I can confirm I have full access to the project working folder.

Can you verify that you have read/write access to the project working folder?

Analyzing & Optimizing Composite Layups / Re: Laminate Optimization Based on Max Laminate Strain

Exactly. Use the laminate strain analysis method to implement a strain cut-off.
There's an example within the HME document.

I am attempting to perform sizing on a non-fea project and I get the error shown below. Any help would be greatly appreciated.

Can you elaborate on how to go about doing that? Do you mean modifying the material laminate allowables in the material (Strain: Compression Open Hole for example) to the target strain, then toggling on composite strength, laminate, compression, open hole failure analyses for example?

What about using the laminate strain allowables?

Analyzing & Optimizing Composite Layups / Laminate Optimization Based on Max Laminate Strain

« Last post by dana.frye on June 23, 2023, 04:31:21 AM »

I am looking to optimize a laminate within a non-fea project, based on a single criteria. I wish the peak strain in the global laminate X direction to be less than a specified value. How can I go about doing this? I tried to add a value to the strain X field of the properties tab within the sizing form, but it does not appear to impact the sizing in any way. I cannot seem to get the "strain limit" failure analyses on the failure tab to impact the sizing either. Any advice?

Material Database / Re: Importing material properties from a FEM in HZ 5.8.11

« Last post by James on May 02, 2023, 09:04:31 AM »

You cannot import material data from FEM (.bdf/.dat) in v5.8. However, you can import the FEM and have it automatically setup the laminates, plate thicknesses and bar sections if you sync-up the FEM material IDs before importing. However, that requires you to manually define the materials prior to importing the FEM.

Material Database / Importing material properties from a FEM in HZ 5.8.11

« Last post by James.rogers@nasa.gov on May 01, 2023, 03:39:01 PM »

I recently gained access to an older version of hypersizer (5.8.11), and I am struggling to identify a way to import material properties from my FEM. Does that functionality exist in this version of hypersizer, or am I only able to import materials from other hypersizer databases?
