Shank tensile failure

WebbMeasurements of the tensile failure strengths of the shank and threads of the bolt revealed that the threads fail at loads which are significantly lower than the breaking strength of … Webbthe two laminate plates induce shear and tension force into the bolt. For the failure of the CFRP-bolt three different failure modes can be observed. First inter fibre failures occur in the contact area with the laminate-plates (Fig. 14 (I)), then the countersunk head of the bolt starts to shear of (see Fig. 14 (II)).

Inspection Procedure for Checking Tension in High-Strength Bolts

Metric Bolts - Minimum Ultimate Tensile and Proof Loads

WebbHowever, if these assemblies are overtightened, the ductile failure mode is by yielding and eventually fracture of the bolt. This type of failure is easily detectable. The use of both HR/HRC and HV systems on the same site should always be avoided because of the risk of confusion and misuse. WebbOverstressing is perhaps the most common cause for bolt failures, and the easiest to determine as well.

The pressure was transmitted by contact elements between the connected plates. The second sub-component transmitted tensile forces from the bolt to the plate.
