Corrosion/Corrosion Fatigue and Life-Cycle Management

Energy-Based Prediction of Low-Cycle Fatigue Life of CK45 Steel and SS316 Stainless Steel

In this paper, low cycle fatigue life of CK45 steel and SS316 stainless steel under strain-controlled loading are experimentally investigated. In addition, the impact of mean strain and strain amplitude on the fatigue life and cyclic behavior of the materials are studied. Furthermore, it is attempted to predict fatigue life using energy and SWT damage parameters. The experimental results demons...

Life Cycle Assessment of Municipal Solid Waste Management in Tehran

Due to increasing solid waste generation and their significant impacts on human health, environmental assessment of the management and disposal methods become more and more important. There are various disposal methods which are the combinations that originate from a wide range of solid waste management systems. In this study, municipal waste of Tehran (which totals to 7507.5 tons/day) is asses...

Multiaxial high-cycle fatigue criterion and life prediction for metals

A new high-cycle fatigue criterion based on the critical plane approach is proposed in this paper. Unlike most of the other multiaxial fatigue criteria based on the critical plane approach, the critical plane is directly correlated with the fatigue fracture plane. The proposed criterion has a wide range of applicability from very ductile metals to extremely brittle metals. Mean stress effect is...

Blutopia: Cluster Life-cycle Management

We have implemented a proof-of-concept prototype named Blutopia that embodies our ideas of a new software life cycle management paradigm driven chiefly by simplicity. Aiming at facilitating management, Blutopia allows administrators to deploy multiple machines fast and effortlessly in as little time as it takes to perform a system reboot. It is equally easy to manage and augment the deployed in...
