This paper summarizes the use of Abaqus/Explicit for FEA of an expandable liner hanger system that comprises an adjustable swage to expand the hanger body, slip ring to hang, and a packer to
seal in a variable-diameter casing.
In this paper, we will present two methodologies developed to improve the quality and efficiency of dashboards. Both the methodologies have been validated by means of a series of experimental tests and therefore it can be used during the design development process.
In this paper the most advanced features currently available in FE analysis (Abaqus/Explicit) have been used to predict the behaviour of a composite structure under low velocity impact. A low velocity impact event on a flat composite plate has been evaluated. The plate has been modelled using solid elements for each composite layer and a user defined material model with a modified Puck failure criterion was implemented.
The paper mainly focuses on the chances and frontiers our research group encountered dealing with high preformance large deformations simulations in geomechanics under highly complex conditions.
This study presents a mesh objective crack band model is implemented in the generalized method of cells (GMC) micromechanics model to predict failure of a composite repeating unit cell (RUC). The micromechanics calculations are achieved using the MAC/GMC core engine within the ImMAC suite of micromechanics codes, developed at the NASA Glenn Research Center.
These gates are designed to withstand the hydrostatic and
transient pressure loads. A phenomenon that is, however, usually overlooked in the design is the hydrodynamic pressure that is built up in the system during an earthquake.
The study was performed using scaled Tabas earthquake acceleration as the input seismic motion. The results of the simulations are presented in form of a parametric study on the effect of culvert tunnel length, venting geometry, dimension and topology of the vents,
existence of notch at the vent opening, and also the cavitation effect.
The methodology is applied to the analysis of dams, lock gates, and large storage tanks, incorporating in some cases a comparison with the results produced by means of simplified analytical procedures.
This paper shows that the lateral stiffness analysis result of vehicle suspension can be improved with the accurate bearing stiffness model correlated with experimental vehicle test data and also, shows which design parameters contribute to lateral stiffness of vehicle suspension.
This report indicates that the 3D electro-thermal model employed in this study characterizes the electro-thermal behavior of the Li-ion battery cells reasonably well.
