Structer
Structural Analysis Toolbox
Free · Designed for iPad. Not verified for macOS.
Structural analysis made easy on iPhone and iPads. Solves common structural analysis problems with visualizations for learning and preliminary analysis.
Structer is a structural analysis toolbox for students and practicing engineers in aerospace structures.
It provides clear calculations and visualizations for common problems in aircraft structural analysis and sizing.
StruCalc is intended for educational use, preliminary analysis, and engineering sanity checks.
**Included Tools:**
• Section Properties & Stress
–Area, centroid, moments of inertia, section modulus, and stress analysis for common sections
• Beam Internal Loads
– Support reactions, shear and bending diagrams for simple beams and combined loading
• Mohr’s Circle (2D Stress)
– Principal stresses, maximum shear stress, and orientation
• Elastic Column Buckling (Euler)
– Preliminary buckling screening for slender compression members with effective length factors
• Stress Due to Axial and Bending Loads
– Compute section stress based on user-defined area, moment of inertias and location.
**Methods and Validation:**
Calculations use standard 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
