We have obtained constraints on the strength and orientation of anisotropy in the mantle beneath the Tonga, southern Kuril, Japan, and Izu-Bonin subduction zones using shear-wave splitting in S phases from local earthquakes and in teleseismic core phases such as SKS. The observed splitting in all four subduction zones is consistent with a model in which the lower transition zone (520–660 km) an...

This paper demonstrates a feasibility study of applying migration, which is widely used as an advanced data processing technique in geophysical exploration, to detect damage in a plate. This technique suggests a scheme that may build a real time, in situ, and quantitative health monitoring system. A linear actuator/sensor array is placed along a horizontal central axis on a square homogeneous i...

In this work, we have explored growth-induced mechanical instability in an isotropic circular hyperelastic plate. Consistent two-dimensional governing equations for a plate under general finite strain are derived using variational approach. The solved the compound matrix method two cases of axisymmetric growth conditions – purely radial, and combined radial circumferential growth. effect on buc...

Abstract The virtual element method allows to revisit the construction of Kirchhoff-Love elements because $$C^1$$ C 1 -continuity condition is much easier handle in VEM framework than traditional Finite Elements methodology. Here we study two most simple suitable for pl...

This paper aims at optimizing the parameters involved in stress analysis of perforated plates, in order to achieve the least amount of stress around the square-shaped holes located in a finite isotropic plate using metaheuristic optimization algorithms. Metaheuristics may be classified into three main classes: evolutionary, physics-based, and swarm intelligence algorithms. This research uses Ge...

A rectangular isotropic two-layer plate of an irregular structure is considered, the edges which are freely supported, and a constant temperature maintained on them. Two-dimensional Kirchhoff-type thermoelasticity equations two-dimensional heat written for inhomogeneous material were used to study stresses in plate. Using method double trigonometric series spatial variables Laplace integral tra...
