Torque
to Yield Tests
Tests can be performed on actual assemblies
to obtain torque-angle graphs that can be used to establish
the torque to reach the yield strength of the bolt. Such graphs
can be used to establish the appropriate torque-angle specification.
They can also be used, with analysis software such as our
BOLTCALC program, to assist in assessing the structural integrity
of an assembly. The advantage of measuring the applied torque
and angle of rotation of the fastener is that tests on the
actual joint can be completed without having to change the
joint stiffness by introducing a load cell.
Torque-angle and bolt preload-angle test information can
also be used to establish the onset of thread stripping and
joint compression failure. Measuring the angle of turn of
the bolt/nut is an indirect way of measuring bolt extension/joint
deformation. This can be used to advantage in many joint measurement
applications.
