R&D Knowledge Sharing Session on Thermal hotspot prediction in HPDC by shape constant’ & ‘Composite Modelling for Low Velocity Impact’

The Department of Mechanical Engineering, Don Bosco College of Engineering held its monthly Knowledge Sharing Session, under the R&D cell on June 26, 2021. Prof. Suraj Marathe presented a technical paper in the first session while the second session was taken by Prof. Harshad Pingulkar on Recent Trends.

Prof. Suraj Marathe presented work from his published technical paper titled ‘Thermal hotspot prediction in HPDC by shape constant’. Prof. Marathe presented his PhD research work in identifying the approximate height of thermal hot spots in casting components manufactured by high pressure die casting. A new shape constant in Chvorinovs rule and thermal modulus were determined that could identify the thermal spots in components manufactured by HPDC. Mould and shape constant was calculated and validated through ProCast simulation for the height of hot spot for standard shapes of cylinder, cube, sphere, pyramid etc. Prof. Marathe concluded his session by providing useful tips to faculties registered for PhDs on compiling their PhD reports and simultaneously publishing technical papers.

Prof. Harshad Pingulkar presented a technical talk titled “Composite Modelling for Low Velocity Impact”. He started the presentation by talking about different types of Impact Studies. He spoke about Length Scale in Composite Modelling. Prof. Pingulkar covered different failure modes in composite. He spoke about different types of contacts between composites while modelling. For low velocity impact Chang Chang Failure Model is used. Step by step he explained Finite Element Modelling of Composites. Various results, plots and results were discussed.

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