This book presents the bending theory of hyperelastic beams in the context of finite elasticity. The main difficulties in addressing this issue are due to its fully nonlinear framework, which makes no assumptions regarding the size of the deformation and displacement fields.  Despite the complexity of its mathematical formulation, the inflexion problem of nonlinear beams is frequently used in practice, and has numerous applications in the industrial, mechanical and civil sectors. Adopting a semi-inverse approach, the book formulates a three-dimensional kinematic model in which the longitudinal bending is accompanied by the transversal deformation of cross-sections. The results provided by the theoretical model are subsequently compared with those of numerical and experimental analyses. The numerical analysis is based on the finite element method (FEM), whereas a test equipment prototype was designed and fabricated for the experimental analysis. The experimental data was acquired using digital image correlation (DIC) instrumentation. These two further analyses serve to confirm the hypotheses underlying the theoretical model. In the book’s closing section, the analysis is generalized to the case of variable bending moment. The governing equations then take the form of a coupled system of three equations in integral form, which can be applied to a very wide class of equilibrium problems for nonlinear beams.

This book presents an innovative and environmentally friendly type of excavated earth-based building material, called Shot-Earth. The use of a common excavated earth as a construction material (both for structural and non-structural applications) has many important advantages, the main one being that the soil can be used as a zero kilo and zero cost material, being used in the same place where it is excavated. This volume collects the main results obtained by the research units in the FIRS2019-00245 research project, funded by the Italian Ministry of Research (MUR) and dedicated to the study of Shot-Earth materials. Many of the exposed contributions concern the optimization of the mixture and application technique, which consists in the application of the mixture sprayed on a support (that serves as formwork), with or without reinforcements, by using a pressure pipe (that is by a high-speed projection). This new construction technique allows to quickly realise a variety of structural systems, even with a complex geometry (like vaults, arches, shells, tunnel coatings, underground tanks, waterproofing of walls for landfills and waste storages, slope stabilization, etc.).  An additional feature of Shot-Earth is that it can be used to realise high energy-efficient buildings. In particular, this innovative technology can improve the capacity of a building to auto-regulate its interior heat and humidity, increasing indoor environment quality and energy performance and reducing building gas emissions.
