Links to sites with useful material for engineers, on line calculators, data, information and sites that are interesting.

All these sites have more content than our short description.




Welded Connections - Simple guide with formulas for quick calculation of welded connections. Very useful and fast when evaluating welded joint strength, without the use of more complex calculations (as finite element analysis).

Stress Ebook LLC -  Aerospace Stress Analysis and Finite Element Analysis. Aerospace Engineering: Free Blog, Free Ebook, and Paid Aerospace Engineering Online Courses"

ENGINEERS EDGE - The site presents many engineering calculators for analysis, including not only structures but also materials, hydraulics, heat transfer, thermodynamics, manufacturing process and design and more.

AEROSTUDENTS - The Aerospace Students Site presents extensive material of the faculty of Aerospace Engineering at the TU Delft, organized by year (precious information for all aerospace engineers). You find also a Forum, updates and accounts. No one remembers everything from school and sometimes we need something from a different aerospace area for our work. Aerostudents is the best place we know to look for this information. 

WebPlotDigitizer - Easy to use, without download, site for digitizing curves. Just point the launch button and start. For XY charts, polar plots, ternary diagrams and maps. Exports data to other applications.

MIL SPECS - This is a link to EverySpec, a free source of specifications, standards and handbooks. Not only the MIL specs but many other specs are available for free download.

MSC Nastran 2012 Quick Reference Guide - A comprehensive listing of statements, parameters, case controls, and bulk data entries for MSC Nastran 2012, essential for all users, from beginers to experienced ones. For more complete information use MSC Nastran 2012 Linear Static Analysis User's Guide

FIREHOLE COMPOSITES - Extensive material on composites failure criteria, composite calculations, FE analysis, composite material data (including Glare). The site presents an amazing diversity of high quality information for the structure analyst. 

EASA All Regulations and Specifications - All EASA regulations, including the ones with links on Regulations pages and all the others (light airplanes, sailplanes, gas balloons and so on).

P/A Engineering - Free on line calculations for Section Properties, Bolt Group, Ramberg-Osgood Stress-Strain curve, Inter-Rivet Buckling Stress, Panel Buckling with axial load and Fastener Huth stiffness.
