Professional Profile
Introduction: Finite element based process simulation can offer valuable guidelines on how the current process parameters should be modified to meet the requirements on the process and the product. In designing an offshore structure, the extreme responses of the structure due to ocean waves must be known. Most of the wave theories that are normally used in the design of
an offshore structure are based on three parameters i.e. water depth, wave height and wave period. In developing a wave theory, a boundary value problem consisting of differential equation and certain boundary conditions describing the various boundaries is solved in an approximate way. In order to determine the stress distribution on offshore structures, the motion
of the structure should be known in addition to the wave forces on it. This requires solving equation of motions of various degrees of freedom. The general solution of these equations retaining all their nonlinearities can only be obtained by numerical means, e.g., finite element scheme.

Structural engineers inspect, analyze, design, plan, and research structural components and structural systems. Their work takes account mainly of technical, economic and environmental concerns, but they may also consider aesthetic and social factors. The education of structural engineers is usually through a civil engineering bachelor's degree, and often a master's degree specializing in structural engineering. The fundamental core subjects for structural engineering are strength of materials or solid mechanics, statics, dynamics, material science, numerical analysis and conceptual structural design. Reinforced concrete, composite structure, timber, masonry and structural steel designs are the general structural design courses. The structural analysis courses which include structural mechanics, structural dynamics and structural failure analyses are designed to build up the fundamental analysis skills and theories for structural engineering students. At the senior year level or in
graduate programs, prestressed concrete design, space frame design for building and aircraft, bridge engineering, civil and aerospace structure rehabilitation and other advanced structural engineering specializations are usually introduced.
Research Area: Finite Element Modeling of Metal Forming, Failure analysis of structures, Reliability Analysis.
Major Projects Undertaken: 1. Reliability-based Uncertainty Modelling of ROLLING Process
Abstract:
In practice uncertainties arise in predicting servicelife or lifetime loads in considering the variability in material properties, workmanship, element dimensions, environmental conditions, inspection, test data, maintenance and so on. Consequently, decisions related to rolling processes are based on uncertain or incomplete information. The present work has developed a sound methodology for modeling uncertainties in rolling process with reference to the reliability assessment. The outcome of this new process clearly indicates drastic reduction in the resistance to deformation with increase in reliability indexes for respective tandem mills. The present approach gives assistance to the mill builders in the design of new rolling facilities as well as to the operators in indicating how better or differently operation may be carried out by computer control of the coldrolling.
Key words: Uncertainty Modelling & Simulation, optimization of Rolling
Process, Finite Element

2. DESIGN VERIFICATION OF FEEDER BREAKER
Abstract
NML was approached to verify the design calculations of Crusher Feeder, which is being developed by TRF, Jamshedpur. Primarily the Crusher Feeder under consideration is proposed to crush ROM coal from 1200mm to 200mm. The crushing is done through a series or rotating carbide tipped pricks which break/ crush the lumps. Materials to crusher are fed from a hopper through a Chain Feeder cum Conveyor, which also conveys the crushed material from the crusher. The major objectives of the present study were to verify the power calculation and optimization of shaft sizes for both Crusher and Chain Conveyor. Detailed analysis, both conventional and FEM, revealed that the motor selected by TRF for Crusher and Chain Conveyor is just adequate. The shaft of crusher as designed by TRF is also safe. Some modifications of Chain conveyor shafts are recommended.
