    The Delft Sand, Clay and Rock Cutting Model (2021)
    IOS Press
    Details
    Publication Date: 2024-04-11
    Description: Sand, clay and rock have to be excavated for a variety of purposes, such as dredging, trenching, mining (including deep sea mining), drilling, tunnel boring and many other applications. Many excavations take place on dry land, but they are also frequently required in completely saturated conditions, and the methods necessary to accomplish them consequently vary widely. This book provides an overview of cutting theories. It begins with a generic model, valid for all types of soil (sand, clay and rock), and continues with the specifics of dry sand, water-saturated sand, clay, atmospheric rock and hyperbaric rock. Small blade angles and large blade angles are discussed for each soil type, and for each case considered the equations/model for cutting forces, power and specific energy are given. With models verified by laboratory research, principally from the Delft University of Technology, and data from other recognized sources, this book will prove an invaluable reference for anybody whose work involves major excavations of any kind.

    100 Years of Prandtl's Wedge (2021)
    IOS Press
    Details
    Publication Date: 2024-04-11
    Description: The biggest problem for a shallow foundation, just as for any other type of foundation, is a failure due to an overestimation of the bearing capacity. This means that the correct prediction of the bearing capacity of the foundation is often the most important part of the design of a civil structure. That is why the publication by Prandtl in 1920 about the hardness of a plastic body, was a major step in solving the bearing capacity of shallow foundations, although it is well possible that he never realised this, because his solution was not made for civil engineering purposes, but for mechanical purposes. Over the last 100 years, a lot of extensions have been made, for example with inclination factors and shape factors. Also many laboratory experiments have been done and numerical calculations have been made. Some even try to extrapolate the failure mechanism for shallow foundations to the failure mechanism around the tip of a pile. All this scientific work leads back to the first publication by Ludwig Prandtl in 1920. This book, “100 Years of Prandtl’s Wedge”, is intended for all those who are interested in these fundamentals of foundation engineering and their history. The Appendices include a copy of Prandtl’s Über die Härte plastischer Körper and of Reissner’s publication of 1924, Zum Erddruckproblem.

    Cycling Pathways (2021)
    Amsterdam University Press
    Details
    Publication Date: 2024-04-02
    Description: In an effort to fight climate change, many cities try to boost their cycling levels. They often look towards the Dutch for guidance. However, historians have only begun to uncover how and why the Netherlands became the premier cycling country of the world. Why were Dutch cyclists so successful in their fight for a place on the road? Cycling Pathways explores the long political struggle that culminated in today’s high cycling levels. Delving into the archives, it uncovers the important role of social movements and shows in detail how these interacted with national, provincial, and urban engineers and policymakers to govern the distribution of road space and construction of cycling infrastructure. It discusses a wide range of topics, ranging from activists to engineering committees, from urban commuters to recreational cyclists and from the early 1900s to today in order to uncover the long and all-but-forgotten history of Dutch cycling governance.

    No Bicycle, No Bus, No Job (2022)
    Amsterdam University Press | Amsterdam University Press
    Details
    Publication Date: 2024-03-29
    Description: For working people, the cost of getting to work, in terms of time and expense, is a crucial aspect of daily life. In the twentieth century, people’s opportunity to travel increased. This did not, however, apply to everyone. The absence of affordable housing near job locations combined with the lack of safe, efficient, and affordable mobility options aggravated social exclusion for some. No Bicycle, No Bus, No Job details how power relations have historically enabled or restricted workers’ mobility in twentieth century Netherlands. Blue-collar workers, industrial employers, and the state shaped workers’ everyday commute in a changing playing field of uneven power relations that shifted from paternalism to neo-liberalism.
