The metaLUG tool allows convenient calculation of single-shear lug margins of safety. Simply input geometry and loads, choose a material and click the 'Calculate' button. This tool uses legacy methods that have been validated through test and years of usage in the aerospace industry. After you're satisfied with your lug design, simply export the results to Excel and move on to the next task.

Highlighted features:

  • Single-shear lug margins of safety
  • Predefined material library
  • Export results to clipboard for use in Excel
  • Free to use!

Coming soon:

  • Double-shear lug margins of safety

The calCLT tool calculates composite ABD matrices and in-plane elastic moduli using classical laminated plate theory (CLPT). It allows users to input custom material properties and any number of plies. The ABD matrix can be used for ply stress and strain development, properties for finite element analysis and many other calculations for laminated composite structures. The results from this tool can be easily copied to the clipboard for use in Excel.

Highlighted features:

  • Custom material input
  • Custom layups, unlimited plies and angles
  • Export results to clipboard for use in Excel
  • Free to use!

Future Products


simuPLATE is your ultimate flat plate buckling tool! Designed to be used with isotropic/metal materials, it is capable of calculating the buckling load factor and margin of safety for plates with various long plate aspect ratios and different boundary conditions. It even handles plastic buckling! This tool gives you stability results quickly and easily. Backed by industry standard methods that have been used for decades, you can size your plates and flanges with confidence and ease. Then conveniently copy your results to the clipboard for use in Excel. Coming Soon!


The Bolted Joint Stress Field Method (BJSFM) is a popular industry standard method for calculating strains and stresses around bolted joints in orthotropic materials. As a legacy method, the original BJSFM program was not meant to be used in browsers or served over the internet. Our version will be. It will be freely available for use on our website at any time and from anywhere.


The J-SEP tool will give you access to joint separation analysis tool freely available online. You will be able to define fastener torque, preload, multiple plate joints and applied loads. The tool will tell you when or if your joint will separate and give you fastener margins of safety.


The MatCurves program will produce full elastic-plastic curves for metallic materials with minimal input. The output from this tool will be useful for non-linear finite element analyses and other calculations that take advantage of material plasticity.
