Application of Numerical Methods in Engineering Problems Using MATLAB presents an analysis of structures using numerical methods and mathematical modeling. This structural analysis also includes beam, plate, and pipe elements, and examines deflection and frequency or buckling loads. The various engineering theories of beams/plates/shells are comprehensively presented, and the relationships between stress and strain, and the governing equations of the structure are extracted. To solve governing equations with numerical methods, there are two general types, including methods based on derivatives or integrals. Derivative-based methods have the advantage of flexibility in modeling boundary conditions, low analysis time, and a very high degree of accuracy. Therefore, the book explains numerical methods based on derivatives, especially the differential quadrature method.

Scientific progress during the last three decades has greatly profited from our advances in understanding complex systems. Fundamental modeling approaches were considerably improved, particularly agent-based modeling, network science, nonlinear dynamics, and system science. At the same time, these approaches have been applied to and adopted by various scientific disciplines, ranging from physics and chemistry to engineering, molecular biology, economics, and the social sciences. This book reflects the success of complexity science both from a historical and a modeling perspective. It uses 25 articles from different disciplines, published over 25 years, to demonstrate the power and problems of modeling complex systems. The book's four parts, Agent-based Models, Network Models, Models of System Dynamics, and Models of Evolution, each provide an informative synopsis of the respective modeling approach.

This book follows the classical division of engineering mechanics as taught at universities in Germany and is devoted to strength of materials, i.e. the determination of stresses and of deformations in elastic bodies. The aim of this book is to provide students with a clear introduction and to enable them to formulate and solve engineering problems in this field. For this purpose, the book provides a number of examples. In a solid (a so-called continuum) under load, a stress state will develop. Due to the load, deformations occur in the solid, thus displacements of the individual body points occur. Displacements are accompanied by strains, the so-called strain state is formed. For a three″ =dimensional body, the above quantities – displacements, strains, stresses – are described by the following set of equations under a given load and prescribed boundary conditions.

This book presents the latest advances in computational and parametric design engineering, as well as digital tools related to manufacturing. It covers design and manufacturing process such as CAD-based design/manufacturing, parametric design, algorithmic design and process automation, and several digital tools and applications. The continuous development of the graphical design environment allows returning to the graphical or grapho-analytical approach for the surface’s enwrapping problems, using capabilities offered by AutoCAD, CATIA, Solid Edge or other graphical design programs. In the present chapter, the method of “virtual pole” is presented and a program for profiling the generating tool was developed for the first time. The programs were written in Visual Basic for Applications (VBA), which allows profiling of tools like: rack-gear tool, gear shaped cutting tool or rotary cutter.

This book highlights the principles, design and characterization of mechanically compliant soft and foldable robots. Traditional rigid robots with bulky footprints and complicated components prolong the design iteration and optimization for keyhole and minimally invasive transluminal applications. Therefore, there is an interest in developing soft and foldable robots with remote actuation, multimodal sensing and machine intelligence. This book discusses the use of foldable and cuttable structures to design biomimetic deployable soft robots, that can exhibit a fair number of motions with consistency and repeatability. It presents the overall design principles, methodology, instrumentation, metamorphic sensing, multi-modal perception, and machine intelligence for creating untethered foldable active structures. These robotic structures can generate a variety of motions such as wave induction, compression, inchworm, peristalsis, flipping, tumbling, walking, swimming, flexion/extension etc. Remote actuation can control motions along regular and irregular surfaces from proximal sides. For self-deployable medical robots, motion diversity and shape reconfiguration are crucial factors. Deployable robots, with the use of malleable and resilient smart actuators, hold this crucial advantage over their conventional rigid robot counterparts.
