Abstract One challenge in Wide Area Measurement System is to design a reliable network which assures data availability. The availability of Phasor Unit (PMU) networks depends on two factors: 1‐Reliable measurements depend performance PMUs and transmission branches, 2‐Reliable the reliability communication used transfer from Data Concentrators (PDCs) control centre. can be improved by choosing p...

This paper presents a new formulation of a well known double hardening model often referred to as the Hardening Soil model. As an alternative to the existing Hardening Soil model’s Mohr-Coulomb failure surface, the new formulation allows for the incorporation of smooth failure surfaces, such as the failure surface proposed by Matsuoka & Nakai or that proposed by Lade & Duncan. Although the inco...

A reliable determination of the onset void coalescence is critical to modelling ductile fracture. Numerical models have been developed but rely mostly on analyses single defect cells, thus underestimating interaction between voids. This study aims provide first extensive analysis response microstructures with random distributions voids various loading conditions and characterize dispersion resu...

The accuracy of a machining model depends on the capability this to describe physical phenomena associated real system. This includes material constitutive and approach used field flow in cutting. In paper, high speed (HSM) Ti6Al4V titanium alloy is developed. cutting proposed considering influence strain hardening, strain-rate, temperature, state stress (e.g., triaxiality Lode parameter) plast...

this lovely mixed metaphor had its origins in a recent presentation by Vicky Niederhauser (2009), who described the need to shift from the longstanding “mother duck” model of clinical education and humorously portrayed the great risks to the “baby-duckling” nursing students as their mother-duck faculty member attempts to lead them through a clinical day. and the “mother lode?” that refers to th...

Elastic and elastic-plastic results are obtained for a semi-infinite slanted through-crack propagating in a symmetrically loaded plate strip with the aim of providing theoretical background to commonly observed plate tearing behavior. Were it is not for the slant of the crack through the thickness of the plate, the problem would be mode I, but due to the slant the local conditions along the cra...
