Failure Analysis of Braking Assembly Systems via FEA Contact Analysis

The purpose of this research was to determine the failure safety margins of the front braking system of a Honda CTX700 motorcycle and perform substantiation stress analysis on the system, as well as to verify stresses with FEM analysis using FEMAP. It should be noted that in this FEA analysis the assembly connections are modeled as linear-contact connections that exert forces on adjacent surfaces in contact and are not trivially meshed as one solid with coincident grids with two different section material properties.

Development of Smart Structures with the aid of thermoplastic conductive & insulating films embedded in conductive structural Carbon Composites

Techniques were developed for insulation of embedded micro devices with Kapton Insulation Films. Thermoplastic Silver filled conductive lines were layout inside the composite prepregs and connection to external processing instruments were developed. Structural Fatigue Testing were performed to determine residual life and possible structural degradations.

Development of Pure Shear Material Properties in FRP Composites

A Modified Iosipescu Pure Shear test specimen is designed. Three element strain gage rosettes are used to measure the strains produced in the test specimen during the pure shear test. These data are used to determine the material's shear moduli.

Pin Failure for Tie-Rod Attachments

Uniaxial tensile test of the tie-rods for attachment pin failure investigations and FEM validation modeling was performed. The symmetrically loaded pin carried more load than the un-symmetric loaded pin before failure.

Development of Linear Capacitive Pressure Sensors

FEM models were built and optimization was performed to develop linear capacitive pressure sensor. The structural system has a mechanically linear deflection behavior at the center boss section leading to elimination of the electronic linearization of the capacitance.
