TL;DR: In this paper, the effect of ultrasonically assisted drilling (UAD) on carbon fiber-reinforced plastics was investigated using a 3 mm drill bit and an extensive experimental study was conducted using ∅3 mm drill and tool wear.

TL;DR: Graphene oxide (GO) was chemically functionalized to prepare polyurethane (PU) composites with improved mechanical and thermal properties as discussed by the authors, which can form homogeneous dispersions in DMF solvent and PU matrix, as well as provide a good compatibility with the PU matrix.

TL;DR: In this paper, the nanoscale interfacial characteristics of thermosonic copper ball bonding on aluminium metallization were investigated, and it was found that ultrasonic vibration swept oxides of aluminium and copper from parts of the contact area, promoting the formation of intermetallic compound Al2Cu (approx.20nm) where oxides persisted, an amorphous aluminium oxide layer connected with a crystalline copper oxide.

TL;DR: In this article, a finite element model of bone cutting is developed and compared with experimental results, which allows the interaction between the bone and cutting tool to be studied, hence enabling the evaluation and optimization of the cutting procedure.

TL;DR: In this article, an experimental study and numerical simulations of fracture processes in a bovine femoral cortical bone tissue were considered, where a set of experiments was conducted to characterise fracture toughness of the bone tissue in order to gain basic understanding of spatial variability and anisotropy of its resistance to fracture and its link to an underlying microstructure.
