The idea of our approach is to define modal composite damping in system in proportion to strainenergy within the mode shape, as independent computer program. This approach allows to take into account soil damping in modal analysis.

This paper describes how Siemens Energy large scale steam turbines R&D has faced this challenge by developing ‘STARpost’ and provides many more field outputs beneficial for hot turbomachinery R&D and an environment for convenient visualization.

This study aims at using the FEM to demonstrate the impact of individual root models in anchorage process with consideration to different rooting patterns and to estimate the stress distribution in soil during the pulling out process.

A coupled MBS-FEM-simulation approach is presented. The used programs are Adams and Abaqus. MpCCI (Multi-Physics Code Coupling Interface) is used for a copled simulation.

In this paper an automated design technique using nonlinear finite element analysis is presented and validated with experiment for RCDBs. This nonlinear finite element automated design technique was used to design the reinforcement for a RCDB.

In this paper, we propose an efficient approach to generate more accurate Approximation model using less Teacher data. In this approach, Isight will search peaks and valleys of current response surface using optimization drivers, add them to Teacher data, and update the response surface automatically.

In this work the quasi-static response of thermoplastic butt-joint stiffened beam in bending conditions is modeled. In these panels, the stiffener is connected to the skin by a short-fiber reinforced filler.

Presented in this paper is an alternative approach to load measurement which leverages the Finite Element Method in

This study presents the calculation identifies the location and number of duty cycle repeats associated with the first appearance of 1 mm cracks for the selected duty cycle, providing an example of how fatigue analysis may be applied to understand damage development in elastomeric components.

This paper presents an overview of some of the ship structural analyses, the simulation automation Isight models created, and a

The details of this interface are shown and several correlation examples of varying complexity are provided. Using this improved process will speed up workflow and improve the accuracy of SEA simulations.

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.
