What is lug analysis?
LugCalc is a calculator software tool for lug analysis theory and estimating the static structural strength of pinned lug joints used in mechanical designs. Combining material, geometry, and loads, LugCalc will walk you through the analysis steps required to estimate a lug joints static strength. These calculations can be used to asses a joints suitability before full scale testing.

What is LugCalc and what is the calculator used for?
LugCalc performs lug analysis calculations based upon the U.S. Air Force published method. LugCalc provides the ability to batch process 1000’s of lug analysis calculations and automate the documentation process. Typical uses of LugCalc include fittings, lifting lugs, actuator ends, and other structural connections. LugCalc operates in both US customary and metric unit systems.

How should I use the analysis results?
Lug analysis methods are estimates based upon historical testing captured in print publications. Two engineers can arrive at different solutions to the same problem using the same data. In mechanical design, lug threshold estimates are considered a starting point. All designs, especially safety critical designs, should be verified and validated via other methods and physical testing before use.
