Structer vs SteelKit

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

SteelKit is the workshop tool for people who work with steel: fabricators, blacksmiths, steel contractors and designers. FULL PROFILE CATALOG Look up IPE, IPN, UPN, HEA, HEB, HEM, round tubes, rectangular tubes, angles, rounds and flats. Each profile shows the weight per meter and the dimensions. WEIGHT IN A FEW SECONDS Enter the length and the quantity and read the weight. It also works for a profile that is not in the catalog: just enter the sizes. SHEETS Pick the thickness and the sheet size and read the weight. Smooth, ribbed and tread plate. DEVELOPMENTS Cones, reducers and square-to-round. See the part in 3D, turn it with your finger and save the flat pattern as PDF or DXF. PLATES AND FLANGES Set the holes and the center hole, check the preview and export the DXF for cutting. MATERIAL LISTS Add the pieces, set the price per kg and get the total weight and a cost estimate. Matching pieces combine on their own. From the list you prepare the request for your supplier. OFTEN USED PROFILES The profiles you open most stay within reach. You can clear that history when you want. WORKSHOP TABLES Threads, wrench sizes, welding and specific weights, always on the phone. UNIT CONVERTER Switch between millimeters and inches, kilograms and pounds, and the other measures you use in the shop. SUPPLIERS Keep names, notes and contacts. Everything stays on the phone. WORKS OFFLINE No account and no internet. The data is already on the phone, even with no signal. LANGUAGES Italian, English, French, German, Spanish and Romanian. Made for the workshop, with large numbers and few steps.
