Application Brief: Design Optimization of Progressively Crushing Rails
Progressive crush
In this application brief, a new strategy is presented for using HEEDS Professional to optimize energy-absorbing rails when a progressive crush is desired. As demonstrated in the paper, this approach yields designs that consistently exhibit progressive crush behavior without significantly sacrificing the total energy absorbed.

Book Review: Evolutionary Computation in Practice

Red Cedar Technology staff members Erik Goodman, Ron Averill, and Ranny Sidhu authored a chapter entitled, "Multi-Level Decomposition for Tractability in Structural Design Optimization," in the recently published volume, Evolutionary Computation in Practice.

Erik Goodman, CTO of Red Cedar Technology, and Professor of Mechanical, Electrical and Computer Engineering at Michigan State University, provides the following review of the entire volume:

This book is loaded with examples in which computer scientists and engineers have used evolutionary computation - programs that mimic natural evolution - to solve real problems. They aren't abstract, mathematically intensive papers, but accounts of solving important problems, including tips from the authors on how to avoid common pitfalls, maximize the effectiveness and efficiency of the search process, and many other practical suggestions.

Some of the authors have already won "Humies"- Human Competitive Results Awards - for the work described in this book. I highly recommend it as a concentrated source of good problem-solving approaches that are applicable to many real-world problems.
