Set up in CDS
- Link equal facesheets and the core between loading blocks.
- Enter core and facesheet through-thickness moduli.
- Enter measured core, bond and facesheet tensile strengths.
- Review extension and the separate strength demands.

About this ASTM reference
Standard Test Method for Flatwise Tensile Strength of Sandwich Constructions
Active catalog edition checked October 10, 2026. The official standard defines the physical method; the CDS example below has a narrower modeling scope. Full procedures remain on ASTM’s site.

What this CDS case represents
Read the actual ASTM standard ↗Uniform flatwise sandwich tension. Bondline compliance and progressive debonding are excluded.
This analytical or measured-data model provides its own curves and metrics. Synchronized failure playback is not supported; a mounted fixture view does not imply that contact, crack growth or impact history is solved.
Instructional model comparison, not experimental validation or ASTM certification. Physical testing requires the licensed standard and a qualified test program.
