Displacement behaviors

This article addresses the challenges of constructing urban tunnels in soft ground using tunnel boring machines, emphasizing geological behavior, tunnel lining loads, and soil displacement. FEM analytical and simulation methods are employed to calculate surface settlements, face-support pressure, and lining load, with a focus on evaluating geological influences on subway line design.

In the paper "Nonlinear static analysis of bidirectional functionally graded sandwich plates using a higher-order finite element formulation" the nonlinear static behaviors of bidirectional functionally graded sandwich (BFGSW) plates are investigated using a finite element procedure. The plates consist of three layers, a homogeneous core and two bidirectional functionally graded face sheets. A nonlinear finite element formulation in sense of the von Karman nonlinear strain-displacement relation is derived in the basis of a higher-order shear deformation theory.

The nonlinear buckling behaviors of the functionally graded graphene platelet reinforced composite (FG-GPLRC) doubly curved shallow shells under external pressure in the thermal environment are introduced and investigated in this paper. The Donnell shell theory and the strain-displacement relationship of von Karman are used. At the bottom surface of FG-GPLRC doubly curve shallow shells, the FG-GPLRC stiffener system in the transverse, longitudinal, or/and oblique directions is installed to increase the bearing capacity of the shallow shells.

The purpose of this work is to offer a method for detecting structural damage utilizing the standardized index of the beam's deflection influence line difference as input data for the evaluation procedure. The displacement influence line used in the evaluation is calculated using the findings of the behavior analysis of the reinforced concrete beam's finite element model when subjected to a moving load.

The obsevation from experimental results indicates that: (1) interface shear behavior between well-graded coral soils and steel structure follows the strain hardening rules; (2) the magnitudes of friction resistances between two materials are related to the gradation and grain size of coral soils, for coral sand limit sliding displacement is around 1mm with interface friction angle of 27.9o while for coral sandy-gravel these values are 2-3mm and 32.

The size dependent large displacement behavior of planar microbeams and microframes is studied in this paper using a corotational beam element. To account for the size effect, the modified couple stress theory (MCST) is employed in conjunction with Euler-Bernoulli beam theory in deriving the internal force vector and the tangent stiffness matrix of the beam element.

A submarine area close to the Turkish and Greek border between the cities of Samos-Greece and Seferihisar-Turkey has been shaked on October 30, 2020 by a Mw= 6.9 earthquake. In this study, the finite source mechanism of the Samos earthquake was investigated using geodetic methods and the coseismic behavior of the earthquake was modeled. The observed coseismic displacements at 62 sites were inverted for the fault geometry and the slips. The mainshock did not generate an on-land surface rupture. However, the uniform slip modeling shows a finite source of 43.

In this study, 1000 data sets randomly generated by the FEM through iterations are used for the training process to get optimal weights. Based on these obtained optimal weights, beam behaviors under the changes in material distribution through thickness could then be predicted. In this model, the ANN’s inputs are the gradation index of the power-law distribution and thickness, while the outputs are compliance and beam displacements. The computed results are verified against those derived from the FEM.
