Determining appropriate fastener dimensions and pre-tensioning force requires careful consideration of anticipated loads, material properties, and environmental factors. A typical analysis involves assessing tensile stress, shear stress, and bearing stress to ensure the chosen fastener can withstand applied forces without failure. For example, engineers might calculate the required diameter of a bolt securing a structural member subjected to specific wind loads.
Accurate assessment of fastener performance is crucial for structural integrity and safety across various engineering disciplines, from mechanical and civil to aerospace engineering. Historically, these assessments have evolved from simplified hand calculations to sophisticated computer-aided engineering (CAE) software incorporating finite element analysis. This progress allows for more precise predictions of fastener behavior under complex loading scenarios, contributing to safer and more efficient designs.
