The limit analysis of masonry structures is a topic of great interest and relevance, as these structures constitute a large part of the world's historical and cultural heritage. The authors proposed a formulation that allows evaluating the stability of curved structures like arches, vaults, and domes made of masonry and the calculation of the collapse multiplier of the applied loads. The approach has started from the analytical solution of the equilibrium of domes of revolution, obtaining the self equilibrating stress by interpolating polynomials. Moreover, we calculated the actual elastic response of the structure by the finite element method. Finally, the used strategy superimposed the elastic stress to the self-equilibrated ones as the starting point of the optimization process. The procedure constitutes an effective way of assessing the structural safety and the limit load of structures; such an approach fulfills the requirements of the 'upper bound' theorem of the limit design. The proposed method can give a twofold response, namely the limit multiplier of prescribed load conditions and the safety assessment of a prescribed load level. The paper presented some examples of parabolical domes subjected to self-weight and variable loads; by applying the procedure, we calculated the load limits and the corresponding residual stress. Moreover, the thrust line at the incoming collapse is also derived.

Cambridge's Jacques Heyman provides a thorough and intuitive understanding of masonry structures, such as arch bridges, Greek temples, and Gothic cathedrals. Although his approach is firmly scientific, Heyman does not use complex mathematics. Instead, he introduces the basis of masonry analysis, then considers individual structures, through lucid and informative text. 5 photos. 100 line diagrams. 3 tables.

This open access book contains a structured collection of the complete solutions of all essential axisymmetric contact problems. Based on a systematic distinction regarding the type of contact, the regime of friction and the contact geometry, a multitude of technically relevant contact problems from mechanical engineering, the automotive industry and medical engineering are discussed. In addition to contact problems between isotropic elastic and viscoelastic media, contact problems between transversal-isotropic elastic materials and functionally graded materials are addressed, too. The optimization of the latter is a focus of current research especially in the fields of actuator technology and biomechanics. The book takes into account adhesive effects which allow access to contact-mechanical questions about micro- and nano-electromechanical systems. Solutions of the contact problems include both the relationships between the macroscopic force, displacement and contact length, as well as the stress and displacement fields at the surface and, if appropriate, within the half-space medium. Solutions are always obtained with the simplest available method - usually with the method of dimensionality reduction (MDR) or approaches which use the solution of the non-adhesive normal contact problem to solve the respective contact problem.

The aim of Plasticity Theory is to provide a comprehensive introduction to the contemporary state of knowledge in basic plasticity theory and to its applications. It treats several areas not commonly found between the covers of a single book: the physics of plasticity, constitutive theory, dynamic plasticity, large-deformation plasticity, and numerical methods, in addition to a representative survey of problems treated by classical methods, such as elastic-plastic problems, plane plastic flow, and limit analysis; the problem discussed come from areas of interest to mechanical, structural, and geotechnical engineers, metallurgists and others. The necessary mathematics and basic mechanics and thermodynamics are covered in an introductory chapter, making the book a self-contained text suitable for advanced undergraduates and graduate students, as well as a reference for practitioners of solid mechanics.
