Analytical modeling and simulation of metal cutting forces for engineering alloys
In the current research, an analytical chip formation model and the methodology to determine material flow data have been developed. The efforts have been made to address work hardening and thermal softening effects and allow the material to flow continuously through an opened-up deformation zone. …

Analytical Modeling of Multi-Fractured Horizontal Wells in Heterogeneous Unconventional Reservoirs
Current analytical models for multi-fractured horizontal wells (MFHW) generally neglect reservoir heterogeneity, typical seepage characters of unconventional reservoir, partially penetrating fracture and various fracture damage mechanisms. In this thesis, three linear flow models have been …

Analytical Modeling and Diagnosis of Penetration Rate Performance of PDC Bits
… uncommon, were also found. This study developed analytical models to describe some of these interactions. The other questions addressed were whether some form of balling causes slow ROP in deep shales drilled with OBM and whether diagnostic symptoms could be defined to determine which form(s) of …

Analytical Modeling of Waveguide-fed Metasurfaces for Microwave Imaging and Beamforming
<p>A waveguide-fed metasurface consists of an array of metamaterial elements excited by a guided mode. When the metamaterial elements are excited, they in turn leak out a portion of the energy traveling through the waveguide to free space. As such, a waveguide-fed metasurface acts as an antenna. …

Analytical Modeling of the Repair Impact-Damaged Prestressed Concrete Bridge Girders
… between repair methods was made by creating analytical models of a prototype girder setup. FRP overlays were seen to restore the most strength, while strand splices were seen to restore the most ductility. From observation, combining repair methods resulted in an additive effect on strength, …
