Implication

Systematic review reveals multi-bolt coupling and interfacial degradation mechanisms in flange-bolted joints, highlighting parameter identification challenges.

Key Points

Synthesize physics-driven constitutive modeling, interfacial nonlinear dynamics, and multi-bolt degradation mechanisms in bolted flange connections.
Conducted a systematic review establishing a unified classification framework for joint interface models, including static friction, velocity-dependent dynamic friction, and hysteresis stick–slip models.
Evaluated constitutive model parameter identification bottlenecks, multi-bolt elastic interaction effects, experimental sensing limitations, and physics-informed machine learning applications.
Multi-bolt annular flanges exhibit pronounced inter-bolt elastic interaction, circumferential contact pressure non-uniformity, and chain-reaction degradation patterns that do not occur in single-bolt connections.
Common constitutive formulations, particularly time-variant Iwan-type models, face critical parameter identification constraints regarding multi-solution risk, noise sensitivity, and cross-condition transferability.
