TL;DR: In this paper, the authors explored vibration-based techniques together with their use as diagnostic tools for structural health monitoring, and found that a change in the natural frequency of the cracked bar due to crack-tip plasticity and vibro-impact behavior linked to interaction of crack faces, obtained from experiments, led to generation of higher harmonics; this can be used as a diagnostic tool for structural Health monitoring.

TL;DR: In this article , an innovative longitudinal-torsional complex-mode ultrasonic vibration-assisted actuator with single excitation and an elliptical locus is presented employing a piezoelectric transducer and a stepped horn with spiral grooves.

TL;DR: In this paper , the effects of morphology and orientation of graphite inclusions on a response of an entire unit cell to thermal loading are investigated, and the influence of periodic and fully-fixed boundary conditions on the damage behaviour of compacted graphite iron is discussed.

TL;DR: In this article , a dynamic mode-I energy release rate of a double cantilever beam (DCB) under impact from a striker is derived for the first time for isotropic and orthotropic composite materials, accounting for DCB properties, a striker mass and an initial impact velocity.

TL;DR: In this paper, a finite element approach to study crack-tip behavior for a directionally solidified nickel-based superalloy subjected to high-temperature fatigue loading in vacuum and air was presented.
