Nylon denture base material could be a useful alternative to poly (methyl methacrylate) (PMMA) in special circumstances such as patient allergy to the monomer. The aim of this study was to evaluate the flexural properties of a nylon denture base material (Lucitone FRS), a conventional compression-moulded heat-polymerized (Meliodent), a compression-moulded microwave-polymerized (Acron MC) and an...

Removable partial dentures (RPD) are traditionally made of casted alloys using the lostwax technique. Laser-sintering is a new additive manufacturing technique for processing RPD metal frameworks that can produce RPDs frameworks quickly with high precision and at low cost. The objective of this study was to characterize the mechanical, crystallographic, and biocompatibility properties of RPD Co...

The effect of an electroless Ni-Cu-P coating on the fatigue behavior of quenched and tempered CK45 steel has been investigated. The fatigue tests under rotating bending conditions have been conducted in three different conditions of uncoated, as-deposited and shot peened prior to the coating deposition. The results indicate that plating of the base steel leads to a fatigue life reduction. The d...

The highest elevation of the Tibetan Plateau, lying 5,700 m above sea level, occurs within the part of the Lhasa block immediately north of the India-Tibet suture zone (Yarlung Zangbo suture zone, YZSZ), being 700 m higher than the maximum elevation of more northern parts of the plateau. Various mechanisms have been proposed to explain this differentially higher topography and the rock uplift t...

The advancement in 3D printing techniques has raised the hope to use additively manufactured parts as final products various industries. However, due layer-by-layer nature of AM parts, they are highly susceptible failure when subjected fatigue loading. This review provides a detailed account influence parameters on properties by fused filament fabrication (FFF). Existing standards for testing p...

The mechanical properties of thick-walled SiO2 nanotubes (NTs) prepared by a sol-gel method while using Ag nanowires (NWs) as templates were measured by using different methods. In situ scanning electron microscopy (SEM) cantilever beam bending tests were carried out by using a nanomanipulator equipped with a force sensor in order to investigate plasticity and flexural response of NTs. Nanoinde...

The stiffness degradation of hybrid carbon/glass fibre composites are investigated under cyclic loading in three-point bending. compared to toughened interlayered with PA 6,6 nanofibre (veil) and a matrix 5% rubber particulate. With the incorporation veil into hybridised composite, interface experienced extensive localised delamination, due crack deflection, causing longitudinal cracking betwee...

In this study, a phenomenological tissue damage model has been developed to describe the fatigue-induced stress softening and permanent set of biological tissues. Since damage evolution is an irreversible dissipative process, following thermodynamic principles, an equivalent strain proportional to the strain energy of the material is employed as the damage criterion. The maximum equivalent stra...
