✦ Synopsis


The main objective of this work is to investigate the effect of size, surface roughness and the interference value on the static and dynamic stiffness of shrink-fitted joints.

Most of the previous research has been concerned with the joint holding load under static conditions without consideration of many of the applications in which the joints are exposed to dynamic loading. The dynamic performance of a machine tool is greatly affected by the collected response of its joints. In many applications in which shrink-fitted joints are used, such as engines and machine tools, their dynamic characteristics can be an important factor in deciding the overall performance of the machine. Hence, studying the joints' stiffness characteristics under static and dynamic conditions is of importance.

## Abstract The secant stiffness of the stress – strain – hysteresis during a cyclic or dynamic loading with very small strain amplitudes is sometimes called β€œdynamic” stiffness of a soil. In contrast, a β€œstatic” stiffness is obtained from the first loading curve in oedometric or triaxial tests. In
