This paper is an attempt to compare artificial neural networks and response surface methodology for modeling surface roughness and cutting force in terms of better coefficient of determination (R2), lower root mean square error (RMSE) and model predictive... see more

This paper summarises the numerical and theoretical studies of the incompressible, laminar airflow through a single flow passage of a blade-less radial turbine. Furthermore, it yields the numerical validation of the simplified theoretical model for incomp... see more

The purpose of this work is to shed light on the problem of the fretting damage of a mechanical assembly bolted in three dimensions. This study requires the analysis of the stress fields in the Cartesian coordinates in terms of the angle and the radius of... see more

The process of friction stir welding is a significant advance in the field of research on the Friction welding technique known for several decades. This assembly technique has obvious originality since welding is performed in the solid state, which can he... see more

Despite crucial efforts invested into computational methods, explicit dynamics simulation of cutting operations may still be unacceptably expensive. Therefore, in many cases a two-dimensional model is considered. Here an overview of the possibilities of t... see more

A solitary wave in two-dimensional, incompressible, turbulent free-surface flow over a plane bottom with small, constant slope is considered. The flow is assumed to be slightly supercritical with Froude numbers close to 1. If the flow far upstream and far... see more

The objective of this work is to present a numerical modeling of crack propagation path in functionally graded materials (FGMs) under mixed-mode loadings. The minimum strain energy density criterion (MSED) and the displacement extrapolation technique (DET... see more

In this paper the effects of active fluxes during gas metal arc welding (GMAW) were investigated. Eight different types of active fluxes, with different oxygen content, and MnO – SiO2 flux mixtures were applied to the surface in 20 vol.% steps before... see more

In this study the effect of basalt and carbon fiber content on quasi-static and fatigue mechanical properties of polyamide 6 are investigated. Composites with different fiber contents were melt compounded, then specimens were injection molded. The presenc... see more
