Topology optimization offers optimal material layouts, enabling automation in the design of devices. Given the recent advances in computer technology and additive manufacturing, to…
A modeling framework for coupling plasticity with species diffusion
M. S. Joshaghani, K. B. Nakshatrala
This paper presents a modeling framework---mathematical model and computational framework---to study the response of a plastic material due to the presence and transport of a chemi…
On boundedness and growth of unsteady solutions under the double porosity/permeability model
K. B. Nakshatrala
There is a recent surge in research activities on modeling the flow of fluids in porous media with complex pore-networks. A prominent mathematical model, which describes the flow o…
On numerical stabilization in modeling double-diffusive viscous fingering
M. Shabouei, K. B. Nakshatrala
A firm understanding and control of viscous fingering (VF) and miscible displacement will be vital to a wide range of industrial, environmental, and pharmaceutical applications, su…
Global sensitivity analysis of frequency band gaps in one-dimensional phononic crystals
W. Witarto, K. B. Nakshatrala, Y. L. Mo
Phononic crystals have been widely employed in many engineering fields, which is due to their unique feature of frequency band gaps. For example, their capability to filter out the…
