Abstract As composite material techniques mature, the study of functionally graded (FG) structures under multi‐field coupling has become increasingly important. For FG spherical shells, inhomogeneous distribution stress fields leads to permanent plastic deformation when external force is applied. In addition, Lorentz from constant magnetic can significantly affect mechanical properties and behaviors materials (FGM). this study, elastoplastic states shells include four deformations, such as...
We have developed a mixed-grid finite element method (MGFEM) to simulate seismic wave propagation in 2D structurally complex media. This divides the physical domain into two subdomains. One subdomain covering major part of is divided by regular quadrilateral elements, while other uses triangular elements correctly fit rugged free surface topography. The local stiffness matrix any identical and matrix-vector production calculated using an element-by-element technique, which avoids assembling...
In this paper, we introduce the so-called symplectic discrete singular convolution differentiator (SDSCD) method for structure-preserving modelling of elastic waves. presented, physical space is discretized by DSCD, whereas an explicit third-order scheme used time discretization. This approach uses optimization and truncation to form a localized operator. preserves fine structure wavefield in complex media avoids non-causal interaction when parameter discontinuities are present medium....
We have developed a new scheme with high accuracy and parsimonious memory requirements to reconstruct the source wavefield in reverse time migration (RTM). This used linear combination of boundary several layers imaging domain. The value was stored one buffer, making computer requirement our method equal that only layer wavefield. coefficients for were determined by an optimization technique minimized finite difference error Fourier optimal presented finite-difference (FD) stencils 5–15 grid...
SUMMARY The western Yunnan is located in the SE Tibetan Plateau, and characterized by active Tengchong volcano (TCV), complex crust–mantle coupling intense earthquakes. To elucidate tectonism Yunnan, we construct a 3-D S-wave velocity model to 80 km depth via ambient noise tomography using dense seismic stations. Our shows significant low-velocity anomalies at different depths crust uppermost mantle. Compared with results of previous regional tomography, image consistent large-scale source...
Functionally graded material (FGM) can optimize the mechanical properties of composites by designing spatial variation properties. In this paper, stress distribution functionally panel with a central elliptical hole under uniaxial tensile load is analyzed. Based on inhomogeneity and three different gradient directions, effects concentration factor damage are discussed. The study results show that when Young’s modulus increases distance from hole, decreases compared homogeneous material,...
SUMMARY The Tengchong–Baoshan region (TBR) is located at the margin of southeastern Tibetan Plateau (SETP) and subject to complex interaction among multiple tectonic blocks. Therefore, TBR approximate for investigating mechanism responsible SETP its surrounding Based on eikonal equation-based seismic tomography, we obtain high-resolution P-wave velocity azimuthal anisotropy depths 0–40 km beneath TBR. We discover a large magma reservoir (with horizontal scale ∼50 vertical ∼15 km) in...
An osteon consists of a multi-layered bone matrix and interstitial fluid flow in the lacunar-canalicular system. Loading-induced system is critical for osteocyte mechanotransduction remodelling.To investigate effects lamellar structure heterogeneous material properties on distributions seepage velocity, an idealized as hollow two-dimensional poroelastic slab model subjected to cyclic loading.

SUMMARY The Qinling belt is a transitional zone lying among three units: the North China block (NCB), South (SCB) and northeastern Tibetan Plateau (NETP). Owing to interaction of these units, complex deformation has occurred in belt. Although many studies have been conducted understand mechanism belt, some key issues are still under debate, such as whether middle-lower crustal flow exists beneath western (WQB). High-resolution images subsurface structures essential shed light on mechanism....
This work studies the evolution of microstructure, texture, and anisotropy pure titanium foils by symmetric rolling (SR) asymmetric (ASR) subsequent annealing. The as‐received material shows equiaxed alpha grains strong transverse texture (S‐T texture), which leads to severe anisotropy. index plane (IPA) yield stress (YS) ultimate tensile (UTS) is 15.2% 7.5%, respectively. With increase deformation, S‐T mainly transformed into a mixed (T texture) direction (R balances start‐up slip system...
