TL;DR: In this article, a novel machining technique known as Ultrasonically assisted turning (UAT) is shown to dramatically improve machining of these intractable alloys, which is capable of high MRR with an improved surface quality of the turned work-piece.

TL;DR: A novel finding of this study is the fact that significant regional variation of stiffness derived from two-phased FEA model with individual trabecula representation correlated highly to regional morphology obtained from in-vivo HR-pQCT images at the distal tibia.

TL;DR: In this paper, a comprehensive dynamic mechanical analysis (DMA) material characterisation activity for all constituent layers of two modern-day thermoformed soccer balls is described, and the resulting material data are used to define a series of viscoelastic finite element (FE) models of each ball design which incorporated the through-thickness composite material properties, including an internal latex bladder, woven fabric-based carcass and polymer based outer panels.

TL;DR: In this paper, a hybrid turning for turning of Ti-15V-3 Al-3 Cr-3 Sn alloy was presented, where cutting insert is vibrated in velocity direction with the help of ultrasonic transducer and external heat is provided to the machined workpiece to gain collective benefits of both arrangements in cutting of hard-to-cut alloys.

TL;DR: In this article, the effects of cutting and vibration parameters (e.g., amplitude and frequency) on the stress distribution in the cutting region were analyzed using finite element simulations on ultrasonic and conventional bone cutting.
