V B Shaibu was born in Thrissur, a town in Kerala state, India, on 8th April 1982. "Thermomechanical Investigation of Dissimilar Welding of AISI 304 Stainless Steel with Commercially Pure Copper" was the title of his Ph.D. dissertation. He has very confident in using ANSYS and COMSOL software for computational modeling of thermo-mechanical and fluid systems. He has five years of undergraduate teaching experience in various colleges, institutes, and coaching centers. he has additional five years of industry experience in the field of air conditioning (Packaged Air Condition Division) as a marketing engineer responsible for the design and management of Air Conditioning projects at Blue Star Ltd and LG (dealers). he has recently completed one of his research projects as a Senior Research Fellow at NIT Rourkela on "The Design and Development of Dynamic Mechanical Analyzer" in the IMPRINT-sponsored project.

An experimental study on CO2 laser beam welding of AISI 304SS and Cu dissimilar pipes Sushanta Kumar Sahu, Bikash Ranjan Moharana, V.B. Shaibu, Susanta Kumar Sahoo International Journal of Mechatronics and Manufacturing Systems, 2016 Effect of process parameters such as laser power and welding speed on CO2 laser beam welding (LBW) of commercially pure copper (Cu) pipes with AISI 304 stainless steel (SS) pipes is investigated in the present study. Laser power is varied from 1.5 to 3.5 kW; heat source velocity/scan speed is varied from 0.72 to 4.5 m/min; and beam diameter is maintained at 0.18 mm operating in Gaussian mode. The microstructural developments and mechanical properties of the welded samples are investigated. It is observed that acceptable microhardness values, across the weld pool and along the depth direction have been obtained, and those are found to be related to the temporal continuation and quenching of plasma. The mechanical properties in terms of tensile stress realised values up to 286.232 MPa and the fracture was observed to be outside the weld zone. The growth of keyhole phenomena has been simulated and compared with experiment.
Computational Modeling of Dissimilar Metal CO2 Laser Welding: Applied to Copper and 304 Stainless Steel V.B. Shaibu, S.K. Sahoo, A. Kumar Procedia Engineering, 2015 This research work analyses the thermal, metallurgical and physical stages of AISI 304 Stainless Steel-Copper dissimilar couple during laser welding in keyhole mode numerically and then validated experimentally. 10.6 μm wavelength CO2 laser welding machine is used for conducting this experimental analysis and the process is simulated by finite volume method. For making the dissimilar couple, a volumetric Gaussian heat source is applied symmetrically on the both metal domain and it is getting an asymmetric molten pool shape. It is observed that the computational model have good concurrence with the experimental results, after the calibration between simulation and experimental results for the same parameter set.
