NAFED-2017 – Second National Finite Element
Developers/FEASTSMT Users Meet At ISRO HQ, Bangalore
15th December 2017
Mr. Chandra Shekhar Singh (HOD, ECE Department), Dronacharya College of Engineering, Gurgaon attended NAFED-2017 – Second National Finite Element Developers/FEASTSMT Users Meet at ISRO HQ, Bangalore on 15th December 2017. 150 delegates attended the meet.
The objective of the meet was to widen the scope of software development into the academic curricula of educational institutions, which will in turn attract talent and therefore improves software capability. It brought together researchers, academician to further enhance software capabilities. It was attended by professors, research scholars and students of various academic institutions and domain experts working in research laboratories and industries.
The meet was intended to showcase the capabilities of Finite Element software for structural analysis named FEASTSMT, developed by Vikram Sarabhai Space Centre (VSSC).
The dignitaries present on the dais are Dr. K. Sivan, Director, VSSC, Shri. S Sridhar, Chairman, organizing team, NAFED-2017, Dr. K Jay Kumar, Convener, Organizing Committee, NAFED-2017, Dr. K. Kanakrajan, FEAST developers, Head, CSTED and Dr. S.A Pallanasswami, Contributers, FEAST.
The meet was inaugurated by Shri A S Kiran Kumar, Chairman, ISRO/ Secretary DOS, at a function presided over by Dr. K. Sivan, Director, VSSC. In his speech, Dr. K. Sivan stressed the importance of indigenization in the area of software tools used within the country. In the meet, Chairman, ISRO released the new version of the software FEASTSMT 2017.
The inaugural session followed by the paper presentation divided in three sessions. Dr. C.S. Upadhyay, Associate Professor, Department of Aerospace engineering, IIT Kanpur gave the keynote address and discussed the finite element analysis, analysis and design of composite structures. He also emphasized the importance of micro level structural analysis of materials and possible causes of failure by quoting a well-known example sleipner oil platform which was catastrophic failure, due to a design flaw, that resulted from an error caused by non-conservative concrete codes and inaccurate finite element analysis modeling of the tricell, which formed part of the ballasting/flotation system.
Chairperson: ShriPoomani, Scientist, ISAC Rapporteur: Dr. KR Pradeep, Scientist, VSSC
The broad objective of session 1 was to discuss the FEAST software capabilities in the design of indigenous structure analysis software, Development of Contact module, Vibration analysis of 800 N thruster for chandrayaan-2 mission, comparison of viscosity stress analysis, structural analysis of spacecraft, formulation and implementation of inertia relief method of static analysis, estimation of discontinuity stress at the weld repair and burst pressure of a rocket motor, structural analysis of GHRC telescope.
Chairperson: Shri A.P Vora, Scientist, SAC Rapporteur: Shri. K.V Muralidhar, ISAC
Session 2 mainly focused on the thermal analysis of a typical nozzle using FEAST software and comparing results with other software such as ANYSYS, Structural analysis of crane hook, shock spectrum generation, thermal analysis of Fin and Tube type heat exchanger, Buckling analysis of connecting rod, Structural and thermal analysis of missile Radome, axisymmetric finite element analysis of GFRP igniter case, finite element analysis of gridded payload adapter for GSLV MKIII, Thermo Mechanical analysis of Piston and solid motor nozzle using free standing charred SP.
Chairperson: Shri Mahadesh Kumar, ADA Rapporteur: Shri. G Vinod, VSSC, ISAC
Session 3 objective was to discuss the Finite Element analysis of Electromagnetic devices using FEAST software. Smt. Sreerekha, TT&IC, VSSC discussed the technology transfer and industry coordination module of the FEAST software. She also motivates academician to provide contribution in the development of various module in the software.
The session also focused on the development of nonlinear dynamic module in software, generation of MESH techniques for solids model, Micromechanical modeling of smart materials, finite strain plasticity and crystal plasticity, 2D vector finite element method for electromagnetic scattering computations, Implementation of progressive damage models for fiber reinforced composites, Finite element implementation of small strain Drucker-Prager model.
Panel discussion was held at the last to conclude the session, Shri. M.V Dhekane, Former Director, IISU/ISRO, opined that ISRO wants more private companies to make launch vehicle and satellite related components for the government run enterprise. ISRO has offered to assist them with technology transfer and in building the required infrastructure to help incubate a space industry in the country.
The program was knowledgeable and the sessions were interactive and covered the important aspects of FEAST software. The participants got the overview of the procedure of Structural Analysis with FEAST software and the meet was a good learning experience.
