About this ASTM reference

Standard Practice for Filled-Hole Tension and Compression Testing 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-strength comparison. Fastener contact and preload 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.

CDS currently represents the compression comparison branch. This page does not imply support for filled-hole tensile-strength prediction.

Model basis · equation and interpretation

Demandopen = σgross/XOHC; Demandfilled = σgross/XFHC.

σgross is the shared gross-section compression demand. XOHC and XFHC are independently measured open- and filled-hole compressive strengths. Match layup, geometry, fit and environment. A filled hole is not assumed to restore strength. These curves scale nominal demand, not damage or load–deflection.

Instructional model comparison, not experimental validation or ASTM certification. Physical testing requires the licensed standard and a qualified test program.
