The Dynamic Flexibility Method in Structural Dynamics: Application to Nonuniform Beams and Plates and to Cavity-Backed Plates
Efficient and accurate analytical or semi-analytical solutions have been developed for the dynamics of one and two dimensional linear structures employing elemental dynamic flexibility formulation. This dissertation is divided into three parts. In the first, the elemental flexibility formulation is …

Semi-analytic simulations of microring resonators with scattering elements
… or sharp cut-off mirror. The thesis will present semi-analytical solutions to easily anticipate the resultant reflection from the ring for a given scattering element. The results are presented graphically to facilitate understanding of the effects of various design parameters. The structures are …

Development of rate-dependent thermoplastic constitutive models for numerical analysis of ceramics at high-temperature
… is evaluated in model problems allowing for semi-analytical solutions. Material constitutive parameters are obtained from a combination of experimental tests and multi-objective optimization and employed in FE simulations of industrial processes, such as cold-forming of combed finish ceramic …

Modeling Material Degradation Due to Moisture and Temperature
… firm thermodynamic underpinning. We then obtain semi-analytical solutions of several canonical problems to illustrate the nature of the quasi-static and unsteady behaviors of degrading hyperelastic solids. As second part, we propose several non- dimensional parameters that characterize …

Rate-Transient Analysis of Tight Oil and Gas Reservoirs
… analysis (RTA); RTA models are commonly based on analytical solutions to fluid flow equations describing flow through the rock matrix and hydraulically-induced fractures to MFHWs. In addition to MFHW characterization, RTA is used for short- and long-term production forecasting (or estimation of …
