Relevance – While International Organization for Standardization (ISO) standards exist for most lower-limb prosthetic components, they do not include prosthetic sockets.

Static socket testing configuration.

CP Static Strength – Depended on thickness, fabrication method. DL Static Strength – Influenced by material choice, fabrication method. Ductile loading criterion: – Most CSs and all CPs failed in a ductile mode. Brittle loading criterion: – Most DLs failed in a brittle mode.
