Conditions for elasto-plastic strain localization in unsaturated soils

The necessary and sufficient conditions for elasto-plastic strain localization initiation in unsaturated soli massifs are proposed. Unsaturated behaviour is described unsing net stress and suction as independent stress variables and modifying the basic constitutive surface parameters and hardening rules to consider the role of suction. The process is accepted to be static isothermal. The conception that the localization band initiates due to loss of stability of deformation process is used. In that case, the rates of process measures bifurcate. A special example is given to illustrate the application of the obtained conditions

FEM applied in hydro-mechanical coupled analysis of a slope

Landslides can be attributed to a number of factors, such as geologic features, topography, vegetation, weather, or combinations of these factors. Rock and soil mass is involved in tectonic or other natural processes that result in appearance and development of different kind of discontinuities such as faults, cracks and breaks filled with water or softer/harder minerals. The existence of such discontinuities is one of the essential failure sources in landslides

Rethinking Sustainability Towards a Regenerative Economy

This open access book is based on work from the COST Action “RESTORE - REthinking Sustainability TOwards a Regenerative Economy'', and highlights how sustainability in buildings, facilities and urban governance is crucial for a future that is socially just, ecologically restorative, and economically viable, for Europe and the whole planet. In light of the search for fair solutions to the climate crisis, the authors outline the urgency for the built environment sector to implement adaptation and mitigation strategies, as well as a just transition. As shown in the chapters, this can be done by applying a broader framework that enriches places, people, ecology, culture, and climate, at the core of the design task - with a particular emphasis on the benefits towards health and resilient business practices. This book is one step on the way to a paradigm shift towards restorative sustainability for new and existing buildings. The authors want to promote forward thinking and multidisciplinary knowledge, leading to solutions that celebrate the richness of design creativity. In this vision, cities of the future will enhance users’ experience, health and wellbeing inside and outside of buildings, while reconciling anthropic ecosystems and nature. A valuable resource for scientists and students in environmental sciences and architecture, as well as policy makers, practitioners and investors in urban and regional development
