In present study, a mathematical model of the vehicle–floating slab track (FST) interaction is established to investigate the coupled behaviour of vehicle–track system. The FST is modelled as the double Euler -Bernoulli beam including the rail and slab. The railway vehicle is simplified as a multi-rigid-body model. The wheel–rail interface is treated using a nonlinear Hertzian contact model, co...

[1] The 3D Vp, Vp/Vs, Pand S-wave attenuation structure of the Cocos subduction zone in Mexico is imaged using earthquakes recorded by two temporary seismic arrays and local stations. Direct P wave arrivals on vertical components and direct S wave arrivals on transverse components from local earthquakes are used for velocity imaging. Relative delay times for P and PKP phases from teleseismic ev...

Cold rolling process of a major transformation in the form of sheet metal and a wide range of steel products are produced in this way. Elastic deformation during cold rolling working rollers and the inevitable increase in the rolling force. In this study, the effect of elastic deformation during cold rolling mill rollers working on the reciprocating back and forth in tandem with the presence of...

Central Mexico is the site of an enigmatic zone of flat subduction. The general geometry of the subducting slab has been known for some time and is characterized by a horizontal zone bounded on either side by two moderately dipping sections. We systematically evaluate proposed hypotheses for shallow subduction in Mexico based on the spatial and temporal evidence, and we find no simple or obviou...

A new seismic model for crust and upper mantle of the south Central Andes is derived from full waveform inversion, covering Pampean flat subduction adjacent Payenia steep segments. Focused crustal low-velocity anomalies indicate partial melts in segment along volcanic arc, whereas weaker a wide zone are interpreted as remnant melts. Thinning tearing Nazca slab inferred gaps inland projection Ju...

We consider nonlocal minimal surfaces in a cylinder with prescribed datum given by the complement of slab. show that when width slab is large minimizers are disconnected and small connected. This feature agreement classical case surfaces. Nevertheless, we not flat discs, as it happens setting, and, particular, dimension <mml:math xmlns:mml="http://www...

In the article, authors present results of a study flat reinforced concrete beamless floor an existing building. The experiment consisted loading slab in span with water tanks. There were 15 stages total, on average 4 kN. During experiment, data was obtained relative deformations and reinforcement support. Also, observations growth vertical cracks introduced.

The voided slab system has been known as an effective technique to replace a heavy reinforced concrete without the decrease in flexural strength. However, according previous studies, capacities such strength, stiffness and ductility of slabs were practically lower than that solid depending on void shapes details. Therefore, this study, analytical experimental study conducted derive optimal shap...
