A Solver-Decoupled Framework for Cumulative Interfacial Motion Tracking in Discontinuous Contact Problems

Key Points

To address the underestimation of cumulative motion in contact problems and improve tracking accuracy.
Developed a Solver-Decoupled Framework (SDKF) for motion tracking.
Implemented an approach to resolve algebraic cancellation and separate reset mechanisms.
Analyzed the enhancement of contact clearance as a tunable parameter.
Standard solver contact slip underestimated cumulative motion by over 50%.
SDKF achieved a speed increase of 494–1006× in processing times for tracking motion.
The endpoint metric conflated normal and tangential components across all loads.

Abstract

• Standard solver contact slip underestimates cumulative motion by over 50%. • Endpoint metric conflates normal and tangential components under all loads. • SDKF resolves algebraic cancellation and separation-reset outside the solver. • Contact clearance becomes a tunable post-processing parameter (494–1006× faster).
