Afterloadingsystemen
Afterloadingsystemen are devices and configurations designed to apply additional loading to a test specimen after an initial baseline load has been established. They enable staged or progressive loading conditions to simulate service or post-processing effects, such as creep, fatigue, or residual-stress relaxation.
Typically built around a loading frame with servo-controlled actuators, afterload systems may use hydraulic, electric, or
Applications include material testing (metals, polymers, composites), biomechanics research (bone or tissue under additional loads), civil
Key design considerations include compatibility with fixtures, alignment, calibration of sensors, temperature dependence, and control accuracy.
