Accurate prediction of the final shape using numerical modeling has been a top priority in the field of sheet and bulk forming. Better shape prediction is the result of a better estimation of the physical stress and strain state. For experimental and numerical investigations of such estimations, simple benchmark processes are used. In this paper a benchmark process involving forging (flattening...

Recent network analysis research has made remarkable progress on studying complex networks in a social context with machine learning techniques. One example of such a complex network is the system data of the New York Citibike bike sharing program, which consists of the data from 49 million bike trips in New York City since July 2013. By inspecting the dataset, we find out that significantly mo...

The Bénard-von Kármán vortex shedding instability in the wake of a cylinder is perhaps the best known example of a supercritical Hopf bifurcation in fluid dynamics. However, a simplified physical description that accurately accounts for the saturation amplitude of the instability is still missing. Here, we present a simple self-consistent model that provides a clear description of the saturatio...

We discuss the development of a comprehensive mathematical and numerical model for thin-layer flow of complex liquids on solid surfaces. The model includes physical and surface chemistry effects and allows direct prediction of the flow as it evolves in time, until the liquid has solidified. We pay particular attention to the substrate shape and wetting properties as well as viscosity dependence...

DOI:10.17014/ijog.9.2.247-262 Pore pressure prediction using velocity-mean effective stress relationship is introduced in Madura Subbasin which located a compressional tectonic setting. The new workflow accommodates the three principal stresses, those are vertical stress, maximum horizontal and minimum form of mean as compaction main inducing agent. application this has resulted more accurate p...

this paper presents a finite element analysis and its related experimental test of corrugated steel web beams subjected to fatigue loading. a particular focus in this study was set on the fatigue failure arising from the web-to-flange welded joint of the corrugated steel web beam. a detailed three-dimensional finite element model which explicitly includes the geometry of the web-to-flange welds...

Analyses and investigations on river flow behavior are major issues in design, operation and studies related to water engineering. Thus, recently the application of chaos theory and new techniques, such as chaos theory, has been considered in hydrology and water resources due to relevant innovations and ability. This paper compares the performance of chaos theory with Anfis model and discusses ...
