CSiMaterials vs Structer

CSiMaterials is an app that contains construction materials for structural designs. It allows searching, sorting and viewing of materials based on various material properties. Application/Usage: • View construction materials for structural designs • Search and sort material properties based on user selection criteria Target Users: • Site engineers and contractors looking for alternative material properties based on regional availability, or construction constraints • Structural and civil engineers looking for optimum materials and their properties for structural modelling and analysis • Teachers and students searching for materials in member designs and projects Key Features: • Comprehensive list of materials including tendons, cold formed steel and aluminum • Search and sort for materials based on many parameters, including strength and strain properties Key Input: • Material library • Material type, name, or properties Key Ouput: • Material type, name, or properties

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
