This volume presents selected edited papers given at the Symposium on Computational Structure Engineering (CSE 09) co-organized by Tongji University and Vienna University of Technology, held in Shanghai, 22-24 June, 2009.

Owing to great progress in computing technology, in computer as well as in programming technology, computation has become one of the most powerful tools for researchers and practicing engineers. It has led to tremendous achievements in computer-based structural engineering and there is evidence that this tendency will be accelerated.

In recent years, concepts of...

This book explores the rapidly evolving field of acoustic metamaterials, focusing on their ability to manipulate sound waves through asymmetric transmission, acoustic focusing, and acoustic asymmetric focusing. It introduces innovative research methods and achievements, such as the use of underwater plate-like metamaterials, airborne metamaterials, and phase-controlled metamaterials to achieve precise control over sound propagation in 2D and 3D spaces. Readers will be particularly interested in the novel applications of these materials in medical ultrasound, underwater...
