Evaluating Bolted Joint Strength at High Strain Rates

Experimental evaluation of bolted joint strength at high strain rates is a challenging but vital research. In the current study, a single lap bolted joint is studied using a Split Hopkinson Bar Pressure setup. The objective of the study is to understand the effect of variable geometrical parameters in the single lap bolted joint experimentally. Subsequently, only those aspects of these parameters that can confine to the dynamic experimental technique are selected. The challenges of the setup, the role of equilibrium and the occurrence of buckling are all studied critically to understand what is the best method to evaluate the joint strength under impact/high strain rate loading conditions.
