Abstract

The present paper experimentally investigates the effect of a new sleeve device on the deformation capacity and strength of a steel bolt up to failure. The test was conducted on a single bolt with multiple sleeves with varying geometric parameters. The results were then compared to the behaviour of a single bolt to quantify the sleeve's effect on both strength and deformation capacity. Finite element (FE) models were then developed and validated against the experimental tests, these models were subsequently used to conduct further parametric studies. The results of the tests showed that the sleeve device increases the deformation capacity of the bolt by a factor of 8, while maintaining the bolt strength and initial stiffness.
