The fracture patterns of the bolted connection with different overlap lengths are shown here. These vary between 100, 112.5, 125, and 137.5 mm.
Here are the fracture patterns of the bolted connection with different hole diameters. These vary between 4, 5, 8, and 10 mm.
Fracture pattern analysis using a white-light microscope for the screwed samples. This section contains the fracture images from the bolted tests. There were two test series. The first test series investigated the influence of the overlap length on the tensile shear strength of the bolted connection, while the second investigated the influence of the hole diameter on the tensile shear strength of the bolted connection.
