Set up in CDS

  1. Link the stack and circular coupon diameter.
  2. Enter the through-thickness modulus Ez explicitly.
  3. Set tensile force and measured transverse strength.
  4. Review stress–strain and specimen extension.
Circular coupon bonded to end blocksExplicit Ez rather than an in-plane modulusLoaded area and through-thickness deformation
Inputs for this recorded case
  • 25 × 25 × 8 mm
  • 32 plies / 8 mm
  • Selected force 1000 N
  • Explicit source calibration/properties

These are teaching-case inputs, not ASTM-prescribed specimen dimensions or acceptance criteria.

About this ASTM reference

Standard Test Method for Through-Thickness “Flatwise” Tensile Strength and Elastic Modulus of a Fiber-Reinforced Polymer Matrix Composite Material

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 transverse tension. Bond restraint and damage growth 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.
