This book provides an overview of direct methods such as limit and shakedown analysis, which are intended to do away with the need for cumbersome step-by-step calculations and determine the loading limits of mechanical structures under monotone, cyclic or variable loading with unknown loading history.

This book provides an overview of direct methods such as limit and shakedown analysis, which are intended to do away with the need for cumbersome step-by-step calculations and determine the loading limits of mechanical structures under monotone, cyclic or variable loading with unknown loading history.

This open access book presents the outcomes of the research developed within the PNRR T4Y PP 4.7.1 technology transfer project entitled “Open Phigital Platform (physical and digital) for user profiling and advanced, dynamic co-design of interventions on existing and new built environments.” The topics are of interest to the scientific community, as they concern the management of structural and environmental safety information related to cultural heritage. The first chapters in the book deepen the theoretical knowledge concerning cultural heritage analysis, proposing advanced models for damage assessment on structures and their surrounding environments. These models also incorporate uncertainties related to material properties and consider different environmental stressors under three projected climate scenarios for the years 2030, 2050, and 2085.This book also presents some final chapters having a more applicative slant, in which, also thanks to the help of some large-scale case studies, a digital platform will be proposed, to support all the meta-files relating to the security data collected, and this, together with the creation of a Living Lab (physical platform), will allow to propose a methodology for the transfer of digitalized data to different stakeholders: institutions, professionals and local communities.

Articles in this book examine various materials and how to determine directly the limit state of a structure, in the sense of limit analysis and shakedown analysis. Apart from classical applications in mechanical and civil engineering contexts, the book reports on the emerging field of material design beyond the elastic limit, which has further industrial design and technological applications. Readers will discover that “Direct Methods” and the techniques presented here can in fact be used to numerically estimate the strength of structured materials such as composites or nano-materials, which represent fruitful fields of future applications.Leading researchers outline the latest computational tools and optimization techniques and explore the possibility of obtaining information on the limit state of a structure whose post-elastic loading path and constitutive behavior are not well defined or well known. Readers will discover how Direct Methods allow rapid and direct access to requested information in mathematically constructive manners without cumbersome step-by-step computation.Both researchers already interested or involved in the field and practical engineers who want to have a panorama of modern methods for structural safety assessment will find this book valuable. It provides the reader with the latest developments and a significant amount of references on the topic.
