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.

在这个工作thermopl的准静态响应astic 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
conjunction with a physical sample to produce an n-Dimensional load transducer.

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
summary of the predicted man-hour reductions. It also discusses how Isight is predicted to enable meeting schedule demands.

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.

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.

本文分析表明,横向刚度is 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.

The objective of this study is to provide an analysis portal to increase their usage through a larger community. SLM has been used to host the automation of the processes and manage the lifecycle of the data used and generated. This report will describe the initial objectives, the implementation experience and the results obtained.

In this paper, finite element (FE) models are developed for
some of the ballasted track components including wood and concrete crossties, ballast and subgrade. A user material subroutine is employed to predict the failure of wood ties based on an
orthotropic stress criterion.

The mechanical manipulation of the equipment, however, can induce significant sudden movement of the completion tubing string near the tool’s locking mechanism. The rapid movement of the tubing string causes large relative motion and “piston effect” forces between tool components and fluid present in the wellbore.

This presentation will demonstrate how Abaqus can be used to drive design decisions at an early stage in the engine development process.

In this study, the program BSAP was developed to carry out the stiffness analysis by designer easily and quickly. BSAP has three templates; CATIA template, AFC template, and Report template.

A simplified suspension assembly for upper control arm was analyzed, tested and correlated for load deflection data. This documentation reveals the effective utilization of Bushing

本研究显示使用哒ta from these carefully constructed laboratory experiments, we can quantify impact location, magnitude, and linear and angular accelerations of the head. The resultant forces and accelerations are applied to a fully meshed head-form created from MRI data by Simpleware.

This study is focused on analysis of post-repair behavior of composite structures. The objectives are to a) develop efficient computational approach for repaired areas, capturing processes of both damage initiation and growth; and b) demonstrate it in Abaqus on representative examples of composite repair designs.

In this paper, preliminary results from a numerical study undertaken to study abrasive wear of tillage tools by soil particles are presented. The wear process is modeled as a single sand particle scratching at a prescribed speed on the surface of a tillage tool.
