Abstract: A novel nonintrusive technique based on an air-coupled ultrasonic transducer was used to study the hydrodynamic behavior of falling film over metal foam layered horizontal tube. Copper foam having a porosity of 90.5%, ...

Abstract: A suspended pipe breakwater was designed specifically for fishery/pleasure-craft harbors where moderate wave agitations in the harbor basin are admissible. The present breakwater consists of a row of closely spaced pipes ...

Abstract: Durability-related problem of any structure is a very important issue that cannot be overlooked, particularly for the structures located in coastal regions. In the coastal region the deterioration of structures often occurs ...

Abstract: In transient vehicle maneuvers, structural tire deformation due to the large load transfer causes abrupt change in normal contact pressure and slip distribution over the contact patch, and it has a dominant effect on ...

Abstract: A general discrete thin rod model to study the preslip response of a strand of helical wires having wires-to-core friction contacts under constant curvature free bending has been developed for the case of Coulomb stick ...

Abstract: The Army's mission is to develop, integrate, and sustain the right technology solution for all manned and unmanned ground vehicles, and mobility is a key requirement for all ground vehicles. Mobility focuses on ground ...

Abstract: In this investigation, a continuum mechanics based bilinear shear deformable shell element is developed using the absolute nodal coordinate formulation (ANCF) for the large deformation analysis of multibody shell structures. ...

Abstract: Two approaches are commonly used for handling frictional contact within the framework of the discrete element method (DEM). One relies on the complementarity method (CM) to enforce a nonpenetration condition and the Coulomb ...
