Modeling and Simulation of Six-Bed Cyclic Adsorption Process Using in Mercaptan Removal from Natural Gas: Non-Isothermal and Non-Adiabatic Conditions

The Behavior of Suction Bucket under Cyclic Loading in Saturated Lands

Numerical modeling was carried out to investigate the responses of suction bucket foundations under vertical cyclic loading. Numerical results were compared with centrifuge experiment results. Before the capacity of the model suction bucket to resist cyclic loading could be investigated, the static pullout capacities had to be determined. The buckets with different aspect ratio are investigated...

Ratcheting crystal plasticity modeling in microstructure of magnesium alloy under stress-controlled cyclic tensile loading with non-zero mean stress

Todays, the requirement of lowering the vehicle weight for the reduction of the fuel consumption and emissions, one of the methods considered by designers is to use the ligh magnesium alloy under cylclic loadings. In this article, considering the microstructure of the AZ91D magnesium alloy, its crystalline structure, a model for predicting the ratcheting behavior of this alloy was adapted and v...

Cyclic and Monotonic Behavior of Strengthened and Unstrengthened Square Reinforced Concrete Columns

The use of composite materials is an effective technique to enhance the capacity of reinforced concrete columns subjected to the seismic loading due to their high tensile strength. In this paper, numerical models are developed in order to predict the experimental behavior of square reinforced concrete columns strengthened by glass fiber reinforced polymer and steel bars and unstrengthened colum...

On the effect of grain size on rock behavior under cyclic loading by distinct element method

It is well-known that the mechanical behavior of rocks under cyclic loading is much different from static loading conditions. In most constructions, the load applied to structures is within dynamic ranges. That’s why a great deal of attention has been paid towards this field in order to identify the dynamic behavior of rocks in more details. Nevertheless, the nature of dynamic failure in rocks ...
