In the present study, a tough tetragonal zirconia polycrystalline (Y-TZP) material was developed for use in high-speed infrared windows and domes. The influence of the preparation procedure and the microstructure on the material's optical properties was evaluated by SEM and FT-IR spectroscopy. It was revealed that a high transmittance up to 77% in the three- to five-micrometer IR region could b...

A static limit analysis approach is proposed for assessing the collapse capacity of axisymmetric masonry domes subject to horizontal forces. The problem formulation based on sound theoretical framework provided by classical statics shells. After introducing shell stress resultants dome mid-surface, integral equilibrium equations are enforced its typical part. Heyman’s assumptions infinite compr...

This article proposes an progressive-collapse mechanism for suspended-dome structures subjected to cable rupture, based on experimental and finite element results. The anti-collapse can be succinctly described as a node-buckling mechanism: the potential node buckling in local arch-like spatial grid centered unsupported directly determines whether progressive collapse will occur overall structur...

It is necessary to recognize masonry domes’ behavior under gravity loads in order strengthen, restore, and conserve them. The neutral hoop plays a crucial role identifying the dome’s distinguish between its tensile compressive regions. When it comes determining position dome with same brick material, addition curve thickness, support condition located on boundary line significant parameter that...

This work presents the volcanic geology of easternmost sector Trans-Mexican Volcanic Belt, including Serdán-Oriental basin and Cofre de Perote-Citlaltépetl range, two contrasting Quaternary fields. The first comprises dominant monogenetic volcanism bimodal composition isolated rhyolitic domes tuff rings, basaltic andesite maar volcanoes, cinder lava cones, an active caldera complex (Los Humeros...
