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 ↗

Independent joint screening. Contact, preload and a combined interaction envelope 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.

Model basis · equation and interpretation

σbearing = P/(dt); σnet = (P + Pbypass)/[(w − d)t]; τout = P/[2(e − d/2)t].

P is pin load, Pbypass bypass tension, d hole diameter, w specimen width, t thickness and e hole-center distance to the loaded edge. Each nominal stress is compared with its own measured allowable. These independent ratios are not a bearing–bypass interaction surface. Bolt preload, contact, friction and multi-fastener load sharing are absent.

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