Geotechnical Engineering in the XXI Century: Lessons learned and future challenges


Book Description

The first Pan-American Conference on Soil Mechanics and Geotechnical Engineering (PCSMGE) was held in Mexico in 1959. Every 4 years since then, PCSMGE has brought together the geotechnical engineering community from all over the world to discuss the problems, solutions and future challenges facing this engineering sector. Sixty years after the first conference, the 2019 edition returns to Mexico. This book, Geotechnical Engineering in the XXI Century: Lessons learned and future challenges, presents the proceedings of the XVI Pan-American Conference on Soil Mechanics and Geotechnical Engineering (XVI PCSMGE), held in Cancun, Mexico, from 17 – 20 November 2019. Of the 393 full papers submitted, 335 were accepted for publication after peer review. They are included here organized into 19 technical sessions, and cover a wide range of themes related to geotechnical engineering in the 21st century. Topics covered include: laboratory and in-situ testing; analytical and physical modeling in geotechnics; numerical modeling in geotechnics; unsaturated soils; soft soils; foundations and retaining structures; excavations and tunnels; offshore geotechnics; transportation in geotechnics; natural hazards; embankments and tailings dams; soils dynamics and earthquake engineering; ground improvement; sustainability and geo-environment; preservation of historic sites; forensics engineering; rock mechanics; education; and energy geotechnics. Providing a state-of-the-art overview of research into innovative and challenging applications in the field, the book will be of interest to all those working in soil mechanics and geotechnical engineering. In this proceedings, 58% of the contributions are in English, and 42% of the contributions are in Spanish or Portuguese.




From Fundamentals to Applications in Geotechnics


Book Description

The work of geotechnical engineers contributes to the creation of safe, economic and pleasant spaces to live, work and relax all over the world. Advances are constantly being made, and the expertise of the profession becomes ever more important with the increased pressure on space and resources. This book presents the proceedings of the 15th Pan-American Conference on Soil Mechanics and Geotechnical Engineering (XV PCSMGE), held in Buenos Aires, Argentina, in November 2015. This conference, held every four years, is an important opportunity for international experts, researchers, academics, professionals and geo-engineering companies to meet and exchange ideas and research findings in the areas of soil mechanics, rock mechanics, and their applications in civil, mining and environmental engineering. The articles are divided into nine sections: transportation geotechnics; in-situ testing; geo-engineering for energy and sustainability; numerical modeling in geotechnics; foundations and ground improvement; unsaturated soil behavior; embankments, dams and tailings; excavations and tunnels; and geo-risks, and cover a wide spectrum of issues from fundamentals to applications in geotechnics. This book will undoubtedly represent an essential reference for academics, researchers and practitioners in the field of soil mechanics and geotechnical engineering. In this proceedings, approximately 65% of the contributions are in English, and 35% of the contributions are in Spanish or Portuguese.




New Trends in Nonlinear Dynamics


Book Description

This third of three volumes from the inaugural NODYCON, held at the University of Rome, in February of 2019, presents papers devoted to New Trends in Nonlinear Dynamics. The collection features both well-established streams of research as well as novel areas and emerging fields of investigation. Topics in Volume III include NEMS/MEMS and nanomaterials: multi-sensors, actuators exploiting nonlinear working principles; adaptive, multifunctional, and meta material structures; nanocomposite structures (e.g., carbon nanotube/polymer composites, composites with functionalized nanoparticles); 0D,1D,2D,3D nanostructures; biomechanics applications, DNA modeling, walking dynamics, heart dynamics, neurodynamics, capsule robots, jellyfish-like robots, nanorobots; cryptography based on chaotic maps; ecosystem dynamics, social media dynamics (user behavior dynamics in multi-messages social hotspots, prediction models), financial engineering, complexity in engineering; and network dynamics (multi-agent systems, leader-follower dynamics, swarm dynamics, biological networks dynamics).

Book Description

O estresse começou a ser estudado no início do século XX, todavia foi demorado o processo de percepção da influência do cotidiano e do ambiente de trabalho na saúde do indivíduo, os novos processos, tecnologias de informação, aceleração da produção e o dia a dia das metrópoles têm contribuído para o aparecimento de determinados desequilíbrios orgânicos e psíquicos (SOUSA, OLIVEIRA, DAMASCENO, SILVA, 2012).




Advances in Mechanism and Machine Science


Book Description

This book gathers the proceedings of the 16th IFToMM World Congress, which was held in Tokyo, Japan, on November 5–10, 2023. Having been organized every four years since 1965, the Congress represents the world’s largest scientific event on mechanism and machine science (MMS). The contributions cover an extremely diverse range of topics, including biomechanical engineering, computational kinematics, design methodologies, dynamics of machinery, multibody dynamics, gearing and transmissions, history of MMS, linkage and mechanical controls, robotics and mechatronics, micro-mechanisms, reliability of machines and mechanisms, rotor dynamics, standardization of terminology, sustainable energy systems, transportation machinery, tribology and vibration. Selected by means of a rigorous international peer-review process, they highlight numerous exciting advances and ideas that will spur novel research directions and foster new multidisciplinary collaborations.




Guía práctica de elementos finitos en estática


Book Description

El Método de los Elementos Finitos (MEF) es sin duda una de las herramientas más utilizadas actualmente en el ámbito del análisis y diseño de sistemas mecánicos. Permite validar y optimizar diseños de forma rápida y versátil, reduciendo la necesidad de costosas campañas experimentales y ofreciendo al diseñador información muy valiosa sobre el comportamiento del sistema y la influencia que tienen en él aspectos como la geometría, el material, la naturaleza de las cargas, etc. Basado en la extensa experiencia de los autores tanto docente como investigadora y en trabajos para empresas, este libro muestra cómo emplear el método para estudiar problemas reales de diseño mecánico. Con un enfoque teórico-práctico, está dirigido a alumnos del Grado de Ingeniería Mecánica o del Grado de Ingeniería en Tecnologías Industriales con el objetivo de dotarles de las nociones básicas teóricas y prácticas a la hora de afrontar un análisis mecánico mediante este método. La guía se ha dividido en dos partes claramente diferenciadas: En la primera parte se explican los conceptos básicos del MEF, siempre desde un punto de vista eminentemente práctico y con numerosos ejemplos ilustrativos. En la segunda parte se presenta una serie de ejemplos de aplicación de análisis por Elementos Finitos de distintos sistemas mecánicos: rodamientos, rótulas, implantes dentales, uniones atornilladas, etc. Para cada caso se describe cuál el problema que debe resolverse y se explican las características del modelo que se ha desarrollado para lograr los resultados requeridos. Sobre la base de los conceptos presentados en la primera parte del libro, en cada ejemplo se discute sobre si el modelo debe ser tridimensional o bidimensional, qué tipo de elemento habrá que utilizar y cómo será la malla, cómo se aplicarán las cargas y las condiciones de contorno, si bastará con hacer un análisis lineal o será necesario uno no lineal, cuál será el nivel de precisión de los resultados según el modelo empleado y la naturaleza propia del problema. El fin de esta guía práctica es precisamente dotar al futuro analista de Elementos Finitos de los conocimientos necesarios para que sea capaz de desarrollar el mejor modelo para dar respuesta a un problema particular.
