This special issue contains selected papers from among those presented at the ‘‘First International Conference on Mechanical Engineering (INCOM)’’, 2018 held from 4 to 6 January, 2018 at Jadavpur University, Kolkata. The conferencewas organized by the Department of Mechanical Engineering, Jadavpur University. Around 200 papers were presented at the conference in wide ranging areas of mechanical engineering. Based on a preliminary scrutiny, some papers, mostly based on fundamental areas of mechanical engineering, wereshortlisted for consideration of publication in the special issue of Sadhana. The authors of the shortlisted papers were invited to submit extended versions of their works presented at the conference. The submitted papers were reviewedfollowing the review protocol of Sadhana. After multiple rounds of review, eleven papers were finally selected. These papers, apart from being of high quality that meets the standards of the journal, represent different areas like solidmechanics and materials, fluid-structure interaction, heat transfer, combustion and dynamic analysis of mechanical systems.
