Instrumented Bolt Measures Load In Two Ways
Abstract
Bolt instrumented to allow both ultrasonic and strain-gauge measurements of tensile load in bolt during installation and use of bolt in structure. Bolt head design allows interface for ultrasonic transducer installed, while shallow chamfered circumferential groove on bolt shank contains four strain gauges at equal angular intervals wired as a full-bridge transducer.
