A probabilistic model for CPT-based soil classification
Çetin, Kemal Önder (2003-07-09)
Due to lack of soil sampling during a conventional cone penetration testing, it is necessary to classify soils based on recorded tip and sleeve friction values. Currently available semi-empirical methods of Robertson and Wride (1997) and Olsen and Mitchell (1995) exhibit a significant variability in the estimation of soil type based on cone penetration test (CPT) data. Thus within the confines of this paper it is attempted to present a new probabilistic CPT-based soil classification methodology which addres...
A computational model for partially plastic stress analysis of orthotropic variable thickness disks subjected to external pressure
Eraslan, Ahmet Nedim; Yedekçi, Buşra (2014-04-01)
A computational model is developed to predict the states of stressand deformation in partially plastic, orthotropic, variable thickness, nonisothermal, stationary annular disks under external pressure. Assuming a state ofplane stress and using basic equations of mechanics of a disk, Maxwell relation,Hill’s quadratic yield condition, and a Swift type nonlinear hardening law, asingle governing differential equation describing the elastic and partially plasticresponse of an orthotropic, variable thickness, non...
A mean field model of the tetracritical point in ferroelectrics
Salihoglu, S; Yurtseven, Hasan Hamit (Informa UK Limited, 1997-01-01)
This study gives a mean field model with two tricritical points and a tetracritical point. Our mean field model has been applied to the mixed crystal system of TGSe-DTGSe. Our theoretical results are in agreement with the experiments.
A model of angiogenesis by hybrid systems with delay on the piecewise constant part
Karasözen, Bülent; Kahraman, Mustafa (2009-09-01)
An important approach towards understanding the cancer dynamics is the modeling of angiogenesis process. There have been several attempts to model this process. Among them angiogenesis models with time delays, caused by the physical distance between the tumor and the vessel, are the most realistic ones. Recent studies have suggested that those delays can cause oscillatory behavior in the angiogenesis process. In this work we employed piecewise linear hybrid systems with delay on the piecewise constant part....

A model of elastohydrodynamic lubrication of piston skirts in reciprocating engines was developed in the context of a simulation of piston secondary motions. The piston secondary dynamics, skirt lubrication and skirt elastic deformation problems are simultaneously solved in the calculation. The model can represent both conventional and two-piece articulated pistons and also includes a treatment of wristpin lubrication. Skirt deformations are calculated using a skirt compliance matrix derived from a finite e...
