At IIT Kanpur, I’m studying imperfection sensitivity in thin-shell buckling across varied R/t ratios. I benchmarked HEX8, HEX20, and TET10 elements against Hutchinson’s classical buckling pressure and selected HEX20 for its consistently low error across the ratios studied.
I’m building SHELL181 and SHELL281 models for parametric linear eigenvalue buckling studies. This work supports my research into thin-shell design.
At NIT Silchar, I built a COMSOL Multiphysics 5.6 model of Al-on-Cu deposition using friction stir additive manufacturing. I studied temperature profiles and interface temperature, and predicted process parameters in relation to tool rotational speed, traverse speed, and shoulder radius.
