Server Hardening Model Development

2009
In this chapter the authors present essential server security components and develop a set of logical steps to build hardened servers. The authors outline techniques to examine servers in both the Linux/ UNIX and the Windows Environment for security flaws from both the internal and external perspectives.

A Thermal Model for Laser Hardening Simulation

Volume 1: Processing, 2015
Laser hardening is a very flexible and useful process for surface treatment of medium carbon steels, capable of processing varied and complex geometries. In order to enlarge the range of industrial applications to which this process can be applied, a suitable model is necessary in order to reduce the setup time requested for the optimization of new ...

Modelling of the hardening and finishing stages of grind-hardened workpieces

The International Journal of Advanced Manufacturing Technology, 2015
Grind-hardening is a manufacturing process that uses the heat generated within the grinding zone in order to produce surface hardening. After the process, workpieces present dimensional inaccuracies and a poor surface finish. Thus, a finishing grinding operation has to be carried out.

Study of PSHG and its integrated hardening model of hardening layer

The International Journal of Advanced Manufacturing Technology, 2017
Pre-stressed hardening grinding (PSHG) combines with the advantage of grinding hardening and pre-stressed grinding. Ideal residual stress can be obtained along with the hardening effect on the surface of workpiece. In order to study its unique hardening characteristic, the paper divided the comprehensive hardening effect of PSHG into quench-hardening ...

A dislocation-based hardening model incorporated into an anisotropic hardening approach

Computational Materials Science, 2013
Abstract The plastic flow behaviors under monotonic and forward–reverse loading were measured and modeled using a simple dislocation density-based model coupled with the homogeneous yield function anisotropic hardening (HAH) approach. The former model captures the effect of dislocation annihilation due to load reversal and the storage of newly ...

Grind-Hardening Process Modelling

2015
Grind-hardening process is a complex hybrid process integrating heat treatment process with high material rate grinding. The modelling of the process thus is quite complex and a number of aspects need to be considered. The present chapter presents a holistic model able to predict the grinding forces, temperature distribution, metallurgical changes ...

General Kinematic-Isotropic Hardening Model

Journal of Engineering Mechanics, 1999
This paper first points out that an evolution rule of the yield center without a motion component in the plastic strain rate direction leads to ratchetting, while an evolution rule with such a component motion leads to proportional material response. The paper then successfully tackles such a dilemma by proposing a general kinematic-isotropic hardening

Ecurrency threat modeling and hardening

2015 World Congress on Internet Security (WorldCIS), 2015
In this paper I investigate the problem of providing application domain security constraints to distributed systems will maintaining high availability. This study uses the application domain of business loyalty incentives as a motivating example. The loyalty incentives are earned through electronic point and currency programs while the modeled system ...

Computer thermal model for hardening grinding

Journal of Engineering Physics and Thermophysics, 2000
A mathematical model of heat transfer in steel parts under force grinding is considered that allows one to determine the grinding parameters at which a steel layer of prescribed thickness is heated up to hardening temperatures. Results of numerical simulation of the process of hardening grinding are compared with experimental data.
