The work presented demonstrates how Isight may be used to drive STAR-CCM+ and CATIA V5 for parametric optimization. A key requirement from the OEM was to remove time-consuming manual iterations from the design process and this example case was setup to demonstrate the automatic optimization process using their existing design and analysis tools.
This study allows mechanical engineering models to be used in place of legacy constructive solid geometry descriptions, which are far less sophisticated. This capability also allows for the seamless integration of radiation transport calculations with analysis of the resulting thermal and mechanical effects on materials.
The objective of the present study was to develop and validate an explicit FE model of the lumbosacral spine and the FSU L4-L5 using patient-specific in vitro data and to evaluate load-deflection characteristics, contact mechanics and efficiency of the FSU. It is also to create a probabilistic model to efficiently predict the performance of the FSU by incorporating disc and ligament material variability.
The application of the CEL method significantly enhances the capability of the compaction model for simulating multiple machine passes on level ground and slopes, traction behavior under large wheel slip, as well as blade dozing operations. It includes also some application examples for optimizing the design of a new generation of landfill compactors.
This study consists of an Isight application with the aim of automation and optimization of a structural design process of the SAR Plate Assembly. The multiobjective optimization problem that regards this specific helicopter component is handled through the use of 4 different genetic algorithms.
This article presents a numerical model of structural behavior of buckling restrained braces for the seismic protection of buildings. This design provides slender braces, which consequently, would buckle when shortened;conversely, this buckling is prevented by embedding the core in a stockier casing.
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.
