Signal and Data Science
Following are the topical problems of interest under the broad category of multiscale modeling and simulation arising from spatial-temporal signal processing, imaging and the associated problem of data representation, data compression and model-order reduction. Most of these methods are actually quite well established methods used for material structure-property correlation. However, the problem of micro/nano-material structure-property correlation calls for greater insight to the signal characteristics and measured data. Similarly, in composite materials …
Multiscale Modeling & Simulation
Finite Element MethodEnriched field interpolation schemes in finite element in general and its application in spectral finite element method for modeling high frequency elastic wave propagation development of eXtended finite element scheme in time and frequency domains with higher-order spatial field interpolations are being developed. Modeling high frequency elastic wave propagation in complex geometries with discontinuities like cracks, phase change, fluid-solid interface and nonlinear dynamic response of materials have remained challenging …
Bio-Materials and Therapeutics in Bio-Systems and Space Applications
Understanding the structural and functional behavior of biological materials is key to designing better bio-compatible systems such as implant, implantable sensors, therapeutic methods and wearable devices for various enabling functions. Understanding of how biological materials evolve and self-organize is also important in engineering better materials. Behavior of biological materials in space environmental is also an important subject of interest here. We use various computational techniques and tools to analyze and further …
Opto-Electro-Mechanical Materials and Devices
Nano-electronic, nano-photonic, piezoelectric and piezomagnetic materials show strongly coupled and often nonlinear behavior. Design of devices based on these material systems aims to utilize the nano/micro-scale, nonlinear and strongly correlated effects to enhance various aspects of performance and expand various functional scopes. Understanding fundamental processes involved in fabricating such material system and devices are very important. Thermo-mechanically induced deformation, defects and their effects on structure and properties play significant role on …
