Methods and Validation
Calculations use closed-form analytical formulas, cross-checked against independent hand calculations and standard engineering references, including:
– Megson T.H.G — Aircraft Structures for Engineering Students
– Young, W.C. & Budynas, R. G. — Roark's Formulas for Stress and Strain
– Bruhn, E.F. — Analysis and Design of Flight Vehicle Structures
– Niu, Michael C. Y. - Airframe Stress Analysis and Sizing
About
Structer is a structural analysis toolbox built for students and practicing engineers working in aerospace structures. It provides clear, reliable calculations and intuitive visualizations for common aircraft structural problems, supporting learning, preliminary sizing, and day-to-day engineering sanity checks. Our goal is to empower students and engineers with powerful analysis tools at the palm of their hands. Looking ahead, Structer aims to grow into a comprehensive, trusted companion for aerospace engineers—expanding its analysis and visualization capabilities, and continuously bridging academic foundations with real-world engineering workflows.
