Using nodal coordinates as variables for the dimensional synthesis of mechanisms
(Springer, 2018-06)
The method of the lower deformation energy has been successfully used for the synthesis of mechanisms for quite a while. It has shown to be a versatile, yet powerful method for assisting in the design of mechanisms. Until ...
Inspection scheduling based onreliability updating of gas turbinewelded structures
(Sage, 2019-01-28)
This article presents a novel methodology for the inspection scheduling of gas turbine welded structures, based on reliability calculations and overhaul findings. The model was based on a probabilistic crack propagation ...
Fatigue Design of Dental Implant Assemblies: A Nominal Stress Approach
(MDPI, 2020-06-03)
Fatigue is the most common mechanical failure type in dental implants. ISO 14801 standardizes fatigue testing of dental implants, providing the load-life curve which is most useful for comparing the fatigue behavior of ...
On the Use of a Simplified Slip Limit Equation to Predict Screw Self-Loosening of Dental Implants Subjected to External Cycling Loading
(MDPI, 2020-09-26)
Self-loosening of the prosthetic screws is a major mechanical problem affecting roughly 10% of dental implants, according to the literature. This phenomenon may lead to micro-movements that produce crestal bone loss, ...
Load distribution and friction torque in four-point contact slewing bearings considering manufacturing errors and ring flexibility
(Elsevier, 2019-03-16)
This work introduces a methodology for the calculation of the load distribution in four-point contact slewing bearings
considering ball preload, manufacturing errors and ring flexibility. The model is built by the formulation ...
Static structural behaviour of wire bearings: comparison with conventional bearings and study of design and operational parameters
(Elsevier, 2018-10-28)
In wire bearings the rolling process occurs on raceways machined on steel wires, and the rings are
made of light materials such as aluminium. This particular architecture provides both weight and
inertia savings, but ...
