Kinetic rosette patterns and tessellations
Beatini, Valentina (Wit Press, 2017)The paper investigates the possibility to create kinetic rosette patterns and their tessellations by means of modular linkages which rely on the same type and number of symmetry operations as the reference models. The ... -
Large transformations with moderate strains of tensile membrane structures
Beatini, Valentina; Carfagni, Gianni Royer (SAGE PUBLICATIONS LTD1 OLIVERS YARD, 55 CITY ROAD, LONDON EC1Y 1SP, ENGLAND, 2017)Using a classical non-linear theory, we analytically investigate possible ways for transforming the shape of a curved elastic membrane while keeping it tensioned and moderately strained. This is a critical issue because, ... -
A regularized non-smooth contact dynamics approach for architectural masonry structures
Beatini, Valentina; Royer-Carfagni, Gianni; Tasora, Alessandro (PERGAMON-ELSEVIER SCIENCE LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLAND, 2017)A Non-Smooth Contact Dynamic (NSCD) formulation is used to analyze complex assemblies of rigid blocks, representative of real masonry structures. A model of associative friction sliding is proposed, expressed through a ... -
The role of frictional contact of constituent blocks on the stability of masonry domes
Beatini, Valentina; Royer-Carfagni, Gianni; Tasora, Alessandro (ROYAL SOC, 6-9 CARLTON HOUSE TERRACE, LONDON SW1Y 5AG, ENGLAND, 2018)The observation of old construction works confirms that masonry domes can withstand tensile hoop stresses, at least up to a certain level. Here, such tensile resistance, rather than a priori assumed as a property of the ... -
Soap film analogy for anisotropically stretched membranes and cable nets
Beatini, Valentina; Royer-Carfagni, Gianni (SPRINGERONE NEW YORK PLAZA, SUITE 4600 , NEW YORK, NY 10004, UNITED STATES, 2017)Analogical physical models are a preferred technique to intuitively grasp complex engineering problems. It is well-known that the equilibrium minimal-surface configuration of membranes under equibiaxial tension can be ... -
Symmetry-Based Transformable and Foldable Plate Structures
Beatini, Valentina (ASMETWO PARK AVE, NEW YORK, NY 10016-5990, 2017)This paper presents a novel family of modular flat-foldable rigid plate structures composed by assemblies of 4R-linkages. First, in the field of foldable plates, the proposed system is characterized by being not only ...
