In the case of accidental ignition, ammunition containers are designed to fail in a way that minimizes danger to nearby personnel. In the constant effort to improve the performance and safety of such containers, extensive experimental testing is required to assess new or modified designs.
The goal of this work was to simulate both the flow in a rocket engine nozzle and the resulting flow-induced transient loads on the nozzle. This unsteady nozzle flow results in structural dynamic excitation, which contributes not only to nozzle stress and deformation but also to the dynamic loads that are transmitted to the rest of the engine.
This study demonstrates how to arrive at optimum
values of forming process parameters viz. blank size and blank holding force. An Abaqus based stamping process template has been developed with an objective to achieve desired quality of deep-drawn components.
This paper will discuss the question on the interaction forces between the human heart and the valvular prosthesis to illustrate how the core issues are dealt with in the biomedical device numerical simulation practice.
In this study, the analysis parameters have been investigated and a correlation with physical test results has been set. This test is much more important for a light commercial vehicle (LCV) because LCV has bigger roof area, more straight style and as a result of these two properties it has heavier roof panel than the other vehicle.
In this study finite element computations are conducted using Abaqus to simulate indentation of transversely isotropic materials. Indentation simulation is carried out both perpendicular and parallel to the plane of isotropy using a 70.3 degree cone half-angle indenter.
This presentation demonstrate how all of the experimentally observed behaviors of this important material can be accurately simulated using Abaqus. Particular emphasis will be placed on the material model
selection and calibration.
The structural component investigated is a roll mill bar which sustain a plug for atransversal rolling of steel pipes. The improvement of the stiffness of this component is the target of the simulation to achieve the desired flexional displacement. An optimization tool is used to achieve the target in a proper and fast way.
In this paper we identify two components as candidates for weight reduction. In order to achieve this goal without sacrificing the current performance of these components we use ATOM optimization software
within Abaqus environment.
The main goal of this study is to improve the understanding of cure-induced microcracking through the development of realistic numerical models validated with experimental data. Specifically, microcracking predictions of unit cell FEA models of two different fiber architectures are compared with results of micro-computed tomography scans of actual panels with the same fiber architectures.
