Electronic Theses and Dissertations
Embedment in bolted joints is defined as the local deformation of surfaces into one another due to uneven contact. Embedment that occurs after the tightening of a bolted joint can cause loss of preload in the joint potentially leading to failure. VDI 2230, a German standard for bolted joint design, is currently the main source for engineers regarding embedment. It related expected embedment to the surface roughness in steel bolted joints. This research expands on the VDI standard by performing tests on a commonly used aluminum alloy and a steel alloy. Both cold rolled 1045 steel and 6061- T6511 aluminum …
