Set up in CDS
- Link a core-only stack between bonded loading plates.
- Set bonded plan area and the core shear modulus.
- Enter force and matched measured core shear strength.
- Review shear strain and relative plate displacement.

About this ASTM reference
Standard Test Method for Shear Properties of Sandwich Core Materials
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 elastic core shear. Adhesive slip, end effects and cell-scale fields 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.
