Online and offline monitoring of composite bolted joints under tensile load were investigated using piezoelectric transducers. The relationships between Lamb wave signals, pre-tightening force, the applied tensile load, as well as the failure modes were investigated. Results indicated that S0/A0 wave amplitudes decrease with the increasing of load. Relationships between damage features and S0/A...

Abstract In this study, the joint strengths of single-lap bolted and bolted/bonded (hybrid) joints formed by using four different engineering plastics were experimentally investigated. High-density polyethylene (HDPE), ultra-high molecular weight polyethylene, Delrin (POM), Teflon used as plate materials in connections. Standard M6 bolts bolt The specimens prepared single bolted, double bolted/...

Wind and earthquake disasters in the world often cause billions of dollars of damage to buildings, most of which is to non-engineered buildings-especially homes. Wood-frame homes use connectors which exhibit partial rotational rigidity at the member ends, making analytical solutions difficult. This is due to the lack of information about the complex behavior of the connections used in this type...

Stresses in single-lap bolted joints of thick plates are complex and difficult to analyze. The few previous studies of stress through the thickness of bolted joints have been limited to finite element simulations and have been implemented only for the joining of relatively thin plates. Experimental and numerical analyses were conducted to analyze the stress distribution inside thick bolted plat...

In the presented research, a split Hopkinson tension bar (SHTB) was used to measure mechanical response of multi-material single-lap joints in high-rate loading regime. High-performance applications require high-quality measurements properties define safe design rules. Servo-hydraulic machines are commonly investigate such small structures, but they prone produce oscillation-affected force meas...
