PROJECTS

Reverse engineering of a mirror assembly Jan 2012 May 2012

• Studied the functionality with an objective of reducing the weight & other cost functions.

• A DFM/DFA study performed, showed an improvement of 8.87% in die construction cost & 17.2% reduction in overall

assembly time.

• Failure Mode Effect Analysis (FMEA) & DFM/DFA analysis conducted, & a redesign was proposed.

• Comprehensive design for assembly analysis based on Boothroyd and Dewhurst methodology.

• Re design proposed using DFA guidelines making sure that a redesign of the functionality of the model is not done,

rather the embodiment.

• Project helped realize the vital factors and critical areas where cost effectiveness and time makes a remarkable impact.

Multi objective design optimization of a cylindrical pressure vessel Aug 2012 Dec 2012

• Optimizing pressure vessel design by minimizing displacement & cost as a function.

• The design variables critical are thickness of the wall, inner radius, & length of the cylindrical section.

• A Multi objective optimization model was performed using NSGAA II technique in ModeFrontier and VisualDOC

coupled with ABAQUS as an analysis Software.

• Python script enabled integrating ABAQUS with the optimization tools.

• Objectives were achieved by minimizing the material cost for constrained maximized Hoop stress.

Graduate Research Assistant (Clemson University)

Sound transmission loss (STL) in Honeycomb Sandwich Panels using time harmonic steady state frequency

procedure Aug 2012 – May 2014

• Comparison of vibration acoustic behavior of Regular & Auxetic Honeycomb panels coupled with external acoustic

domain using Finite Element Analysis solver (ABAQUS).

• Investigated the effects on STL due to internal air cavity resonances in honeycomb cores & found minor influences on

STL at very high frequencies above 3800 Hz.

• Develop and analyze models exhibiting strong fluid structure interactions (ex. Water as external acoustic domain).

• Transient analysis for special loading case of Ricker pulse interactions for narrow band of frequencies dominated by

single frequency using Abaqus/Explicit.

• Honeycomb cores exhibit stronger structural coupling between panels, increasing stiffness but has reduced STL,

revealing the challenges in designing structures to exhibit both characteristics.

STL of Double Multi Panel structures with Air filled cavities Aug 2012 – May 2014

• Study the effects of different depths of acoustic cavities between panels on sound transmission and associate acoustic

wavelength of sound in relationship with the depth of air cavities.

• Modal frequency response of panels to plane wave interactions & and its NVH characteristics.

• Study STL in low mass and high effective stiffness, thin Multi panel structures with layers of air in between and

comparisons are made with double and single panels.

• For pure sound insulation purposes multi panel configurations with air in between has high STL, however has low

strength and stiffness under other mechanical loads.

Structural analysis using FEA subjected to structural/thermal events Aug 2012 May 2013

• Developed unique FEA codes using MATLAB to solve 1D/2D problems subjected to structural, thermal stresses, heat

transfer as a part of Adv. FEA projects.

• Material characterization & static, dynamic analysis and Implicit, Explicit methods to solve linear/non linear problems.

• Developed FE codes for modal superposition dynamic analysis for structures.

• Develop unique FEA models for structures subjected to thermal, structural, blast impact & dynamic loads using FEA

software. E.g. Abaqus/Standard, Abaqus/Explicit, Ansys, Python.
