Graduate Research Assistant, (Sum 97-Fall 99)
The University of Texas Arlington, Dept. of Mechanical and Aerospace Engineering,
Smart Structures Group (Research funding was provided by National Science Foundation, CMSD)
The research work consisted of FEA design optimization using ANSYS for design and development of linear MEMS pressure sensors (capacitance type) where it would have applications in remote sensing. Optimization schemes were developed for design at micro level constraints of the sensor diaphragm. Classical plate theory and FEA correlations were developed for the sensor diaphragm plate.
Furthermore, new usage monitoring technologies were developed for remote sensing capabilities in composite structures. Smart Materials and Structures were designed and developed by embedding conductive and insulating thermoplastic films within composite prepregs. This technique was used to detect interlaminate ply failures. Insulation techniques with Kapton supported adhesive layers were developed for conductive Carbon composites. Autoclave processing design and manufacturing of the newly developed embedded composite materials were perfected and proved feasible. Experimental off-axis composite-ply failure sensing and detection methods were developed. The structural degradation effects were investigated, for these manufactured structures using these newly developed technologies. Tensile and fatigue tests were performed by MTS machines on these embedded composite laminates to ensure feasibility and structural integrity. Data Acquisition systems were put together and utilized for data gathering and experimental results.
Research presentation in national Smart Structures & Materials Conferences and in engineering journals such as Journal of Smart Materials & Structures, Journal of Applied Mechanics & Engineering and ASME Journal of Electronic Packaging.

Structural Engineering and Mechanics Group (Research funding was provided by Georgia Tech and FHWA)
Experimental stress analysis of the Fiber Reinforced Plastic composite structures with strain gage measurement methods and Photoelastic analysis techniques for determining mechanical properties that include Shear and Tensile strength. Developed a modified Iosipescu test procedure for determining shear properties in pultruded composites regardless of the composite beam height and other physical dimensionalities. This new test procedure was developed to test large scale beams, since the current Iosipescu test fixture allows for small size samples to be tested only. The results were compiled in my M.S. thesis and in research presentation in national Experimental Mechanics Conference.
