Numerical Modeling of the Ice-Conical Structure Interaction Process Using Element Erosion Technique

نویسندگان

چکیده

Abstract Nowadays, the Finite Element Analysis method is widely used, including in field of fracture mechanics, because to grown computing power. Numerical modeling mechanics a developing Ice-Structure Interaction field. One approaches ice failure Method with Erosion Technique, which used among researchers. However, question using material model that most accurately describes behavior taking into account its physical and mechanical characteristics remains open. Also, researchers often overlook strain rate effect on values load. This article presents results numerical interaction level conical support offshore structure. The dependences load value velocity are also presented compared obtained according regulatory documents.

Numerical modeling of erosion using an improvement of the extended finite element method

We present in this paper a numerical model of the erosion of a soil that accounts for both the flow in the open fluid and the flow of fluid through the porous soil. The interface between the open fluid and the soil is represented using a level-set function, and the erosion is controlled by the shear stress vector. The evaluation of the approximate value of this gradient is particularly focused ...

Validation of Erosion Modeling: Physical and Numerical

The overall intent of this research is to develop numerical models of erosion of levees, dams and embankments, validated by physical models. The physical models are performed at 1-g and at high g’s using a geotechnical centrifuge. The erosion is modeled in detail, from beginning to end, that is from the time the levee is overtopped until the levee is breached. Typical quantities measured as a f...

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

Experimental Study of Masonry Structure Under Impact Loading and Comparing it with Numerical Modeling Results via Finite Element Model Updating

Given the sophisticated nature of the blast phenomenon in relation to structures, it is of significance to accurately investigate the structure behavior under blast loads. Due to its rapid and transient nature, blast loading is one of the most important dynamic loadings on the structures. Since masonry materials are widely used as the partition and bearing walls in the existing and newly-built ...
