Set up in CDS
- Link the laminate and define the coupon and hole.
- Enter tensile force and matched measured OHT strength.
- Calculate gross and net nominal stresses.
- Compare gross stress with the measured gross-area strength.
Inputs for this recorded case
- 150 × 36 × 2 mm
- 16 plies / 2 mm
- Selected force 1000 N
- Explicit source calibration/properties
These are teaching-case inputs, not ASTM-prescribed specimen dimensions or acceptance criteria.
Readout & interpretation
- Gross tensile stress
- 13.89 MPa
- Net tensile stress
- 16.67 MPa
- Open-hole demand / measured strength
- 0.03472 —
- Linked laminate thickness
- 2 mm
Measured-data screening. Local hole strains and notch-strength prediction are excluded.
About this ASTM reference
Standard Test Method for Open-Hole Tensile Strength of Polymer Matrix Composite Laminates
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 ↗Measured-data screening. Local hole strains and notch-strength prediction 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.
