Discontinuous Galerkin Method for Interface Crack Propagation
In this communication, a class of non-symmetric/symmetric discontinuous Galerkin (dG) methods with interior penalties for interfacial fracture problems is presented. The behaviour of the interface is
Study of cutting force and surface roughness in the turning of polytetrafluoroethylene composites with a polycrystalline diamond tool
Abstract Despite the importance of the polytetrafluoroethylene (PTFE) composites in many industrial applications, especially for space industry, very little is known about the machinability of these
Machining and surface integrity of polymeric materials
In this paper, measurements of cutting force and temperature developed during orthogonal cutting at different cutting speeds, feed rates and depths of cuts were carried out. During the experiments
Effect of processing parameters and strain rate on mechanical properties of carbon nanotube–filled polypropylene nanocomposites
Abstract The objective of this paper was to evaluate the effect of injection molding parameters, particularly melt temperature and injection pressure, and strain rate on the mechanical properties of
Characterization of viscoelastic properties of molybdenum disulphide filled polyamide by indentation
In this paper, the creep behavior of molybdenum disulphide (MoS2) filled polyamide 66 composite was investigated through sharp indentation at room temperature. Two types of indentation creep test,
Experimental Investigation, Modeling and Optimization of Circularity, Cylindricity and Surface Roughness in Drilling of PMMA Using ANN and ANOVA
In this paper, experimental investigation, modeling and optimization of the drilling of PMMA are performed using the Taguchi Design of Experiments (DOE), analysis of variance (ANOVA) and artificial
Melt rheological properties of ethylene-vinyl acetate/multi-walled carbon nanotube composites
Abstract In this study, the rheological properties of Ethylene-Vinyl Acetate (EVA) filled with various contents (0.1–5 wt.%) of multi-walled carbon nanotubes (MWCNTs) were investigated using a
Study of stress relaxation in polytetrafluoroethylene composites by cylindrical macroindentation
Abstract In the present work, the time-dependent mechanical behavior of three materials from the fluorocarbon family, including PTFE without filler, 15 vol.% regenerated graphite particles-filled
Direct Current method with reversal polarity for electrical conductivity measurement of TPU/MWCNT composites
Abstract In this paper, the electrical behavior of thermoplastic polyurethane (TPU) filled with multi-walled carbon nanotubes (MWCNTs) was investigated. To account for carbon nanotube network
