R&D Knowledge Sharing Session on ‘Microwave Processing of Materials’ & ‘Crash Analysis for Energy Absorption’

The Department of Mechanical Engineering held its monthly Knowledge Sharing Session, under the R&D cell on  February 26, 2021 . The first session was taken by Prof. Sanjeel Naik on Recent Trends while Prof. Raymond Joseph presented a technical paper in the second session.

Prof. Sanjeel Naik presented a technical talk titled ‘Microwave Processing of Materials’. He introduced the topic highlighting the application of microwaves in material processing, in particular, metallic materials for sintering, brazing/joining, melting, cladding, drilling of holes etc. He later highlighted the difference in microwave heating over conventional heating and also explained the microwave hybrid heating setup along with the role of susceptor in absorbing the microwave energy for heating the specimen. He concluded by mentioning the recent developments in joining of materials like Stainless Steel, Gray Cast Iron, Aluminium, Inconel 625 etc. with compatible susceptor mediums.

Prof. Raymond Joseph presented a technical paper on ‘Crash Analysis for Energy Absorption’. He began by highlighting the motivation behind the crash analysis of passenger cars and the current standards. He then presented his research work in studying frontal rails of passenger car during the frontal impact using a dynamic explicit finite element code. A 3D CAD (Computer-aided design) model of the frontal rails was developed in CATIA, pre-processed in HYPERMESH and solved in ABAQUS, studying the displacement and energy interactions for steel and aluminium materials. Lastly, he gave a demonstration on the axial impact of tubes with and without stiffeners using paper models.

The session was attended by teaching and technical support staff from the Department of Mechanical Engineering and coordinated by Prof. Mayur Shetti.
