Field observations and finite element 3-D analysis of soil displacements close to unsupported excavation

Finite Element Method Analysis of Influence on Subway Tunnel Adjacent to Excavation by Excavation Construction

The interaction influence on subway tunnels adjacent to foundation excavation was produced by excavation construction, and it is great significance for the correct assessment of its size and influence on the safety of subway operation. Based on the foundation excavation project, some typical foundation excavation profiles are selected, the calculation and analysis on additional settlement and h...

Thread Pitch Variant in Orthodontic Mini-screws: A 3-D Finite Element Analysis

Orthodontic miniscrews are widely used as temporary anchorage devices to facilitate orthodontic movements. Miniscrew loosening is a common problem, which usually occurs during the first two weeks of treatment. Macrodesign can affect the stability of a miniscrew by changing its diameter, length, thread pitch, thread shape, tapering angle and so on. In this study, a 3-D finite element analysis wa...

Electromagnetic field analysis of novel low cogging force, linear switched reluctance motor, based on 2-D finite element method

This paper deals with electromagnetic design and 2-D (two-dimensional) magnetic field analysis of novel low force ripple linear switched reluctance (LSR) motor. The configuration that has been presented here has a higher number of rotor poles than stator poles, and the purpose of this configuration is to improve the force ripple, which is the weak point of LSRMs. In order to illustrate the ...

finite element analysis of concrete structures using plasticdamage model in 3-d implementation

neither damage mechanics model nor elastoplastic constitutive law can solely describe the behavior of concrete satisfactorily. in fact, they both fail to represent proper unloading slopes during cyclic loading. to overcome the disadvantages of pure plastic models and pure damage approaches, the combined effects need to be considered. in this regard, various classes of plastic-damage models have...
