Composites are future materials and have been finding applications in all fields of engineering (Aero, Civil, Mechanical, Automobile, Marine).
Many FEM software packages are available for analysis & design optimization.
One should first understand the mechanical behavior of the composite structures before using FEM packages.
After the completion of this course one can use the FEM software packages for better quality of professional work and optimum usage of time, computing and human resources.
The course also introduces Artificial Intelligence and Machine Learning concepts for design optimization of composite structures.
Analysis and AI assisted design optimization of composite structures course is about understanding the basic concepts and terminology, different types of fibers and matrices, their properties and applications. Study of micromechanics, macromechanics and failure theories for composites are taught in detail.
The concept of mechanics of laminated composites and analysis will be carried out. In continuation theory and analysis of beams and plates will be studied.
Design of laminates using carpet plots, AML plots are carried out. Design of laminates and artificial intelligence assisted design optimization of composite structures and comparison of artificial intelligence methods are studied.
