What’s on the Elastic Constants poster
A 6-row table: Material · E (GPa) · Poisson ratio.
Typical room-temperature values. Grade and heat treatment shift them.
- Mild steel — 200 — 0.29
- Stainless 304 — 193 — 0.29
- Aluminium 6061 — 69 — 0.33
- Titanium 6Al-4V — 114 — 0.34
- Grey cast iron — 110 — 0.26
- Polycarbonate — 2.3 — 0.37
Shear modulus G = E ÷ 2(1 + Poisson ratio); for steel that is about 79 GPa. Educational reference; use certified data.

- Who is the Elastic Constants poster for?
- Elastic Constants belongs to the Mechanical Engineering section rather than to a school year, because engineering is not something one grade owns. Anyone learning mechanics of materials can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Elastic Constants poster?
- Any deflection or thermal calculation, where E is the number you need. A wall chart earns its place by being glanceable from where the work is happening, so Elastic Constants belongs on the wall where that engineering work actually happens, within glancing distance, rather than filed away.
- What other posters go with Elastic Constants?
- Axial Stress & Strain, Beam Bending Stress and Beam Deflection Cases sit alongside Elastic Constants in the Mechanical Engineering section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Axial Stress & StrainBeam Bending StressBeam Deflection Cases
- Is the Elastic Constants poster free to download and print?
- Yes. Elastic Constants downloads as a free PDF with no account, no email and no watermark, like everything else in the Mechanical Engineering section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Elastic Constants poster print at?
- Elastic Constants is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Elastic Constants loses nothing.Printing guide
