48. End Cartridge, Functional Cartridge and Sacrificial Cartridge
Stable section ID: S05-CON-015-SECTION-49 · 12 content blocks
An End Cartridge is a Cartridge positioned at or near the end of a Member to establish the controlled relationship between that Member and a Node or another structural interface.
It may provide material transition, load introduction, alignment, seating, fastening, inspection access, digital identification, and controlled removal while allowing the main Member to remain comparatively simple.
A Functional Cartridge is a Cartridge whose primary responsibility is to provide an additional engineering function such as sensing, actuation, energy transfer, utility connection, communication, environmental control, fire protection, damping, or robotic interaction.
A Sacrificial Cartridge is designed to experience controlled yielding, wear, deformation, energy absorption, or replaceable damage before more critical or less replaceable entities are harmed.
Sacrificial behavior shall be:
intentional and analytically defined;
inspectable or detectable;
limited to declared load or event conditions;
compatible with safe residual stability;
accompanied by replacement and reverification procedures.
A single Cartridge may perform more than one of these roles only where its combined responsibilities are explicitly declared and verified.
Ordinary damage shall not be retrospectively described as sacrificial behavior. A component is sacrificial only when its controlled response and failure sequence are part of the approved design basis.
