Objectives of the Course
Natural Intelligence is needed to understand the Artificial Intelligence and Machine Learning (AIML) capabilities and limitation.
Advanced research in material science to enhance the life of structures with reduced cost resulted in metal alloys, plastics, composites and nano materials.
Structural design and optimization of components with unusual shapes became possible with FEM software tools such as ANSYS, COMSOL, NASTRON, ABACUS, SYSNOISE, LSDYNA and MATLAB etc.
The fundamental knowledge of stress, strain, shear and torsion in relation to the structures and S-N curves in relation to material fatigue life and failure analysis becomes important.
The interpretation of the FEM software results necessitates for the knowledge of structural system analysis and design optimization.
This course essentially trains engineers/ scientists/ entrepreneurs/ instructors in the industries/ institutes/ universities to optimally design various structural systems for technically superior and commercially viable value-added product to achieve “EMPOWER INDIA WITH SKILL AND KNOWLEDGE” for “AATMANIRBHARA BHARAT ABHIYAN”.
