The implementation of a new 8-node finite element for solving 3D elasticity static problems is considered. idea this based on the projection rare mesh FEM scheme into space lower dimension. resulting hexahedral has number features compared to classical polyline element. This one integration point in eight element, as well presence four parameters that allow you adjust convergence computational ...

The goal of this study was to determine whether there is any biomechanical difference in terms of construct strength with axial loading between volar fixed-angle locking plates with threaded locking vs smooth locking pegs. The control group comprised 7 cadaveric specimens with threaded locking pegs, and the test group comprised 7 cadaveric specimens from the same donor with smooth locking pegs....

While the dominant approach to persistent storage in practice is to use a relational DBMS, there are some specialist applications that rely on object stores. The performance of these applications depends heavily on the efficiency of the object store’s concurrency control mechanism. Today’s predominant concurrency control mechanism is strict two-phase object locking. In the 80s, an interesting a...

Abstract In this paper, a first-order virtual element method for Reissner–Mindlin plates is presented. A standard displacement-based variational formulation employed, assuming transverse displacement and rotations as independent variables. the framework of element, piecewise linear approximation assumed both on boundary element. The consistent term stiffness matrix determined uncoupled polynomi...

Deformation of partially composite beams under distributed loading and free vibrations of partially composite beams under various boundary conditions are examined in this paper. The weak-form quadrature elementmethod, which is characterized by direct evaluation of the integrals involved in the variational description of a problem, is used. One quadrature element is normally sufficient for a par...

A new layered 4-node, 24-degrees of freedom rectangular composite plate element is developed in this paper for nonlinear finite element analyses of FRP-strengthened RC slabs. The layered approach is used to form an integrated plate element for modelling of concrete, FRP, adhesive layer and steel reinforcement with a perfect bond assumption between each layer. Timoshenko’s composite beam functio...

Singing dunes, which emit a loud sound as they avalanche, constitute a striking and poorly understood natural phenomenon. We show that, on the one hand, avalanches excite elastic waves at the surface of the dune, whose vibration produces the coherent acoustic emission in the air. The amplitude of the sound (approximately 105 dB) saturates exactly when the vibration makes the grains take off the...

A mesoscopic analytical model of wrinkling of Plain-Woven Composite Preforms (PWCPs) under the bias extension test is presented, based on a new instability analysis. The analysis is aimed to facilitate a better understanding of the nature of wrinkle formation in woven fabrics caused by large in-plane shear, while it accounts for the effect of fabric and process parameters on the onset of wrinkl...

The main goal of this research is to study the postbuckling behavior nonlocal functionally graded beams. Eringen’s differential model used evaluate influence material length scale in bending response. An improved shear deformation beam theory with five independent parameters utilized, which suitable for use 3D constitutive equations. A finite element derived spectral high-order interpolation fu...
