Nonlinear Responses in Optimization Seminar

in

Vanderplaats R&D, Inc. would like to cordially invite you to our upcoming seminar, followed by lunch, featuring Professor Gyung-Jin Park, Ph.D., from Hanyang University in Korea. Professor Park will be discussing methods to optimize nonlinear transient problems for crash analysis using innovative methods and the GENESIS software. In addition, VR&D engineers will give a brief presentation of some of the developments at VR&D related to optimizing structures for NVH and safety improvements.

After the seminar, VR&D would like to invite you to participate in a mini-workshop in which you will have a hands-on experience with our software products. In the workshop, the participants would go through some examples using GENESIS, Design Studio and an interface to the Equivalent Static Load method.

Nonlinear Dynamic Response Optimization and Topology Optimization Using the Equivalent Static Loads Method

Abstract:
The equivalent static loads (ESLs) method along with its latest improvements and applications are presented. The equivalent static load is defined as the static load that makes the same displacement field as that by a dynamic load at an arbitrary time. Nonlinear dynamic response optimization is performed by the ESLs method as follows: (1) Nonlinear dynamic response analysis is carried out. (2) ESLs are generated from the results of nonlinear dynamic analysis. (3) Linear response optimization is carried out based on the ESLs and the design is updated. (4) The process goes to (1) and continues until the termination criteria are satisfied. Several examples are presented including automobile crashworthiness problems and metal forming problems. Topology optimization using various analysis techniques is presented. Ideas that are still in the development stage are discussed. Various examples, including a flapping wing optimization problem, are also presented.

This seminar is intended for engineers and/or managers interested in structural optimization using nonlinear analysis. Participants of our April 2007 seminar on this subject will benefit by learning the latest developments.

Professor Park graduated from University of Iowa in 1986. He is the author of the book entitled, "Analytic Methods for Design Practice" from Springer, published in 2007

Structural Optimization using GENESIS, Design Studio and ESL Interface Workshop

Abstract:
The workshop gives the participants an opportunity to work with our structural optimization software offerings. The workshop goes through an overview of the features and capabilities of Design Studio and GENESIS. Creating data for different types of optimization and post-processing in Design Studio is covered. Also, participants will have a chance to work with a VR&D interface of the ESLs method using LS-DYNA and Design Studio/GENESIS.

About:
GENESIS is a fully integrated finite element analysis and design optimization software package, written by leading experts in structural optimization. Shape, sizing, topography, topometry and topology optimizations are available to the user.
Design Studio is a design oriented pre- and post-processor graphical interface for GENESIS. Design Studio allows users to display finite element models and to easily create GENESIS design data. It allows users to display analysis as well as optimization results.
