Objective
To investigate the effect of the in situ screw implantation region and angle on the stability of lateral lumbar interbody fusion (LLIF) from a biomechanical perspective.
Methods
A validated L2‐4 finite element (FE) model was modified for simulation. The L3‐4 fused segment undergoing LLIF surgery was modeled. The area between the superior and inferior edges and the anterior and posterior...
In order to solve the structure fatigue caused by long-term operation of cable line defect and failure analysis, to determine the force endured during short circuit and its effect on cable structure layer, and then from the structural mechanics and mechanical analysis of operation process of high voltage cable lines, operation analysis of cable structure parameters and its change characteristics....
In our previous work, it was found that large Bird’s Nest patterned nanofibrous membranes can be simply electrospun from chlorinated polypropylene solution doped with an ionic liquid, and a plausible formation mechanism of Bird’s Nest patterned architectures was proposed. Here, we use Ansoft Maxwell version 12 software (3D, electrostatic solver) to simulate the electrical field distribution of the...
A miniature disk-pivot piezoelectric motor with double rotors using a vibration mode B11 of one nodal circle and one nodal diameter was designed and fabricated. A disk-pivot structure is used to simulate the wobble vibration and an embedded metal cylinder is used to amplify the displacement to obtain a higher rotation velocity. The structure of the stator is analyzed by using Finite Element Method...
According to the basic idea of fluid-solid coupling theory, combining percolation mechanics with rock-soil mechanics and considering threshold pressure gradient and fluid-solid coupling character of low permeability reservoirs, a numerical model is established, which can describe the fluid-solid coupling character in saturated deformable low permeability reservoirs and can be solved by coupling numerical...
