Two safety topics in pipeline engineering are considered: (1) rockfall onto gravel-buried steel pipes and (2) protection of the outer anti-corrosion coating of soil-covered steel pipelines. For both cases, effective protection systems are identified, based on the results of non-linear elasto-plastic Finite Element analyses.

The ECCOMAS Thematic Conference Multibody Dynamics 2005 was held in Madrid, representing the second edition of a series which began in Lisbon 2003. The conference was held under the auspices of the European Community on computational methods in applied sciences ECCOMAS and provided a forum for discussion of several topics, through the participation of 161 researchers from 29 countries, mostly Europeans but also from Africa, America and Asia. This book contains the revised and extended versions of selected conference communications, representing the state-of-the-art in the advances on computational multibody models, from the most abstract mathematical developments to practical engineering applications. This book will be highly valuable for experienced researchers that want to keep updated on the details of the latest driving ideas in this field, but also to researchers approaching the field for the first time, since it provides a useful overview of the most active areas and the efforts devoted by many prominent research groups worldwide.

This volume contains selected papers in three closely related areas: mathematical modeling in mechanics, numerical analysis, and optimization methods. The papers are based upon talks presented on the International Conference for Mathematical Modeling and Optimization in Mechanics, held in Jyvskyl, Finland, March 6-7, 2014 dedicated to Prof. N. Banichuk on the occasion of his 70th birthday. The articles are written by well-known scientists working in computational mechanics and in optimization of complicated technical ***, the volume contains papers discussing the historical development, the state of the art, new ideas, and open problems arising in modern continuum mechanics and applied optimization problems. Several papers are concerned with mathematical problems in numerical analysis, which are also closely related to important mechanical models. The main topics treated include:* Computer simulation methods in mechanics, physics, and biology;* Variational problems and methods; minimization algorithms;* Optimal control problems with distributed and discrete control;* Shape optimization and shape design problems in science and engineering;* Sensitivity analysis and parameters optimization of complex systems.

This book presents a collection of chapters describing the state of the art on computational modelling and fabrication in tissue engineering. Tissue Engineering is a multidisciplinary field involving scientists from different fields. The development of mathematical methods is quite relevant to understand cell biology and human tissues as well to model, design and fabricate optimized and smart scaffolds. The chapter authors are the distinguished keynote speakers at the first Eccomas thematic conference on Tissue Engineering where the emphasis was on mathematical and computational modeling for scaffold design and fabrication. This particular area of tissue engineering, whose goal is to obtain substitutes for hard tissues such as bone and cartilage, is growing in importance.

Multibody dynamics simulation is widely used for prototyping and testing controllers. However, the transfer of controllers initially developed in simulation to real mechatronics platforms requires updating the code in order to interface with physical sensors and actuators. Due to this strong coupling with specific hardware, the controller re-usability is often severely compromised. In the present contribution, we solve this issue by adding a middleware between the controller and the controlled platform (either real or simulated). This framework decouples the controller from the hardware, allows fast controller developments and eases collaborations on large scale projects. Moreover, it offers the possibility to simultaneously control the real and the simulated robot from a unique controller. This paper presents the interface of the Robotran dynamic simulator with the YARP middleware. Robotran leverages symbolic generation of the multibody equations to provide fast and accurate simulations of multibody systems. The speed and accuracy of Robotran make it possible to test real-time controllers in a realistic simulation environment. This framework is illustrated with applications using the COMAN and WALK-MAN humanoid robots.
