TL;DR: In this paper, the natural frequencies for bending vibrations of Timoshenko cracked beams with simple boundary conditions have been obtained, where the beam is modelled as two segments connected by two massless springs (one extensional and another one rotational).

TL;DR: In this article, a simplified method of evaluating the fundamental frequency for the bending vibrations of cracked Euler-Bernouilli beams is presented based on the well-known approach of representing the crack in a beam through a hinge and an elastic spring, but here the transverse deflection of the cracked beam is constructed by adding polynomial functions to that of the uncracked beam.

TL;DR: In this paper, the behavior of a boring bar with a passive dynamic vibration absorber (DVA) for chatter suppression was investigated. But the analysis of the stability of the two-degree-of-freedom model was not considered, and only its first mode of vibration was considered.

TL;DR: In this paper, the authors presented a method for measuring the dynamic fracture-initiation toughness of materials based on three-point bending tests at high loading rates, performed in an experimental device which is a modification of the classical split Hopkinson pressure bar.

TL;DR: In this article, the optimal selection of the parameters of a passive dynamic vibration absorber (DVA) attached to a boring bar was focused on the optimal optimization problem. But the analysis of the stability of the system was limited to the Euler-Bernoulli cantilever beam.
