ACADEMIC PROJECTS

. Finite Element Analysis Programming Project

August' 11 - December' 11

- Developed a program in Matlab to carry out assembly of global

stiffness matrix followed by Finite Element Analysis for plane stress

and plane strain problem using first order quadrilateral element.

number of nodes and nodal coordinates, nodal fixities (constraints),

nodal loads, element loads (including thermal) and element data

(modulus of elasticity, Poisson's ratio, thickness, nodes that define

the element).

- Output file contains Nodal displacement, Nodal reactions, Stresses

and Strains in X and Y directions.

. Modelling and Analysis of IC Engine components

August' 12 - December' 12

- Created 3D model of piston, piston pin, connecting rod, crankshaft

and assembled the parts using Solidworks.

- Performed static analysis for connecting rod and modal, harmonic

analysis for crankshaft in ANSYS.

. Plasticity Induced Crack Closure under Fatigue

September' 12 - December' 12

- Studied Budiansky and Hutchinson's proposed theoretical model for

plasticity induced crack growth in fatigue based upon Dugdale's model.

- Simulated crack closure for plane stress and plane strain cases

using XFEM in ABAQUS.

. SAE at ASU

October' 12 - Present

- Member of Formula Electric Car Vehicle Dynamics team.

- Performed Finite Element Analysis on Chassis Frame to calculate

Torsional Stiffness of the frame in ANSYS.

- Compared the stiffness value with and without including suspension

assembly into the frame model.

. Design of Compressed Air Energy Storage System

January' 12 - May' 12

- Conceptual, Preliminary and Final Design of a CAES for 75 kW power

output using thermodynamics concepts.

DESIGN COURSEWORK

. Advanced CAE Simulation

January' 12 - May' 12

- Performed non linear buckling analysis for lee's frame which

displays both snap through and snap back (Without using arc-length

method).

- Performed non linear analysis for a rigidly pinned (bolts) plate in

bending. Studied the effect of formulations (pure penalty, augmented

lagrange, normal lagrange), interface treatment, behaviour on accuracy

and convergence speed for different contact conditions (frictionless,

frictional, bonded).

- Performed non linear analysis on a fishing rod with different

transverse loads to study large rotations and large strains. Performed

NAFEMS benchmark test to study small rotations, small strains on flat

plate with transverse loading and spherical cap (dome shaped) with

ring load.

Bauscinger effect and Spring back. Analyzed large strains and metal

plasticity in cold upsetting of metal workpiece and compared to

experimental data.

- Performed non-linear analysis on hyper elastic beam supported at one

end to study shear locking, investigated difference between the

behaviour of full integration, reduced integration and enhanced

strain. Analysed forging of a billet to investigate volume locking for

Plane42, Plane182 and Plane182 (Mixed u-P).

- Performed NAFEMS creep benchmark analysis of thick cylinder under

internal pressure. Investigated effect of rate of load application

(NAFEMS visco-plastic benchmark) on cantilever beam.

- Performed linear static analysis of a pressure vessel for 3 types

of elements: shell, solid, axisymmetric and compared the elements.

- Performed linear static analysis on welds for double fillet lap and

t-joint and verified the results.

- Performed linear static analysis of a containment vessel consisting

of liquid, also calculated maximum stresses in the reinforcement rings

and support structure consisting of beams.

- Performed modal analysis on a flywheel for quarter and full

geometry, with and without pre-stress.

- Performed harmonic vibration analysis on a platform supported by

rails with machines mounted on platform with different scenarios

regarding phase differences in loads using modal superposition and

full integration.
