Finite Element Study of Plane Wave Acoustic Phenomena in Ducts
This thesis studied the finite element modeling of plane wave acoustic phenomena in ducts. The study looked into finite element factors such as shape functions, mesh refinement, and element distortion. The study concluded that the higher order shape function eight-node quadrilateral element gave …

Finite element study of geosynthetic encased stone columns in sensitive soft clay
… a range of behaviour was verified by using the finite difference (FD) method in solving the partial differential equations of the soil model for a range of tri-axial test conditions. The model was further implemented in coupled analysis formulation and coded into FEM program AFENA. Various cases …

A finite element study of the effects of residual stress on conical indentation
The finite element method has been used to study the behavior of an aluminum alloy during elastic-plastic indentation by a rigid conical indenter to determine how the indentation process is affected by residual stress. The study was motivated by recent experimental results which showed that the …

A finite element study of bending stress variation in meshed spur gear pairs
A study of the bending stresses in a pair of meshed spur gears using the finite element method is presented. The models analyzed were in the shape of a circular gear with five teeth or a five-tooth rack. A unit torque (1 lbf-ft) was applied as the form of nodal forces on the nodes around the bore …

Dynamic links between short-term deformation and long-term tectonics: a finite element study
… behavior of fault movement. By using 2-D and 3-D finite element models with viscoelastoplastic rheology, I have explored the spatial-temporal strain and stress evolution during seismic cycles, and linked these results to long-term tectonics. In the central Andes, I found that much of the …

A finite element study of the mechanics of micro-groove machining of 4340 steel
… there is a limitation of the experimental study on gathering the cutting performance information such as temperature, stress, and chip formation for the purpose of process improvements. Therefore, a 3D Finite Element (FE) model was developed to study the microgroove cutting process. …
