Analysis of ultrasonic vibration-assisted ball burnishing process on the tribological behavior of AISI 316L cylindrical specimens
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-08-12)
Article
Open AccessIn this study, we analyzed the effects of vibration assistance, combined with a ball burnishing process, in terms of topology, residual stresses, and tribological properties on 316L shafts. The burnishing variables consisted ... -

Relation between mechanical and densimetric properties to fractal dimension in human rib cortical bone
(2023-07)
Article
Restricted access - publisher's policyNumerous prior studies hypothesized a power-law relationship () between cortical bone Young's modulus (E) and density (¿) with an exponent , that has not been previously justified in the literature on a theoretical level. ... -
Mechanical characterization of thermoplastic elastomers based on olefin processed through material extrusion
(Springer Nature, 2023-05-12)
Article
Open AccessThermoplastic elastomeric materials are processable through 3D printing. These materials demonstrate excellent mechanical properties, along with good flexibility. A better understanding of the creation of bonds between the ... -
A strain rate dependent model with decreasing Young’s Modulus for cortical human bone
(Institute of Physics (IOP), 2023-05-11)
Article
Restricted access - publisher's policyThis research studies the dynamic behavior of human cortical bone specimens and investigates their mechanical properties using uniaxial tensile tests. The main experimental finding is that in the range of strain rate ... -
Patient-specific 3D printed soft models for liver surgical planning and hands-on training
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-04-01)
Article
Open AccessBackground: Pre-surgical simulation-based training with three-dimensional (3D) models has been intensively developed in complex surgeries in recent years. This is also the case in liver surgery, although with fewer reported ... -
A new theoretical model for surface roughness prediction in rotational abrasive finishing process
(2023-07-15)
Article
Restricted access - publisher's policyRotational abrasive finishing (RAF) is a new nano-finishing technique in which the finishing forces are applied to the workpiece by the opposite rotations of a stirring-blades and the workpiece. The RAF process allows for ... -
Multi-objective optimization of tool wear, surface roughness, and material removal rate in finishing honing processes using adaptive neural fuzzy inference systems
(2023-04-01)
Article
Open AccessHoning processes are usually employed to manufacture combustion engine cylinders and hydraulic cylinders. Honing provides a crosshatch pattern that favors the oil flow. In this paper, Adaptive Neural Fuzzy Inference System ... -
Wear resistance and friction analysis of Ti6Al4V cylindrical ball-burnished specimens with and without vibration assistance
(Springer Nature, 2023-02-01)
Article
Open AccessThe objective of the research is to analyze the impact of the ultrasonic vibration assistance on the wear resistance due to the topography enhancement caused on Ti6Al4V cylindrical samples after surface modification through ... -
Quantitative analysis of the effects of incorporating laser powder bed fusion manufactured conformal cooling inserts in steel moulds over four types of defects of a commercially produced injected part
(Elsevier, 2023-03)
Article
Open AccessThe introduction of additively manufactured conformal cooling inserts in steel moulds for plastic injection is becoming a recommended standard. Fine adjustment of the temperatures in the mould has demonstrated potential ... -
Soft 3D printing of thermoplastic polyurethane: Preliminary study
(2022-06-01)
Article
Open AccessThermoplastic polyurethane (TPU) is a highly elastic linear polymer composed of soft segments, usually flexible polyester or polyethers. It is widely used in 3D printing technologies using FFF (Fused Filament Fabrication), ...
