Search → Plot → Export. One workflow.

Find the right material. Ship it to your solver.

Every property value links back to where it came from — the U.S. Department of Defense’s aerospace materials handbook (MIL-HDBK-5J), peer-reviewed journal papers you can pull up by their DOI, and the official EU and California chemical lists for compliance. Pick a material, export a solver-ready card to 10 CAE formats.

Diagnostics3 issues
Red-flag checks the card is run through before download — unit mismatches, physically-impossible values, solver-specific pitfalls. Each entry shows the problem and a fix hint.
Warnings2
G_MISSING
Shear modulus G₁₂ derived from E and ν, not measured directly.
Pick a measured shear-modulus row in the source picker if available.
BASIS_MIX
Yield uses A-basis; ultimate uses S-basis. Mixed-basis card.
Switch ultimate to A-basis for design allowables consistency.
Notes1
FATIGUE_REF
S-N curve emitted as comment block (Abaqus has no native fatigue card).
