Reliable computation and local mesh adaptivity in limit analysis
2019
The contribution is devoted to computations of the limit load for a perfectly plastic model with the von Mises yield criterion. The limit factor of a prescribed load is defined by a specific variational problem, the so-called limit analysis problem. This problem is solved in terms of deformation fields by a penalization, the finite element and the semismooth Newton methods. From the numerical solution, we derive a guaranteed upper bound of the limit factor. To achieve more accurate results, a local mesh adaptivity is used. peerReviewed
Innovative Applications and Experiments for the Protection of Archaeological Sites
2020
Nowadays, the protection in situ, the enhancement and the fruition of archaeological sites are issues that are even more relevant, if we take into account the effects caused, in recent decades, by climate change both on the conservation of the most fragile artefacts and on the well-being of visitors. New questions related to the ‘recover of identity’ are raised by the relationships that the protection interventions establish with the environmental context (external) and with the ancient ruins (internal), imposing an interpretation of the project as a union of landscape, morphological, climatic, technical, use and management aspects, or by requiring a holistic and integrated approach, from a…
