Loosening and sliding behaviour of bolt-nut fastener under transverse loading

Considering the efficient productivity and maintainability, most of machine and products has many joints (e.g., fastening, welding and adhesive joints). Especially, the bolted joints have been frequently used for these purposes as machine elements. However, many troubles such as loosening or fatigue...
