The course starts with generalized Hooke’s law and three dimensional stress strain relations putting emphasis on Materials-Mechanics linkage to elucidate mechanical properties of materials. It also includes Energy methods; Torsion of non-circular members; Shear center and Asymmetrical bending of beams; Curved beams; Thick cylinders.
Small oscillations of linear dynamical systems, free and forced vibrations of single and multi degree of freedom systems, normal modes and orthogonality relations, generalized coordinates, and Lagrange's equations, matrix formulation, eigenvalue problem, and numerical solutions, transient response of one dimensional systems. Introduction to continuous system, vibration measurement and analysis, closed-loop control, conventional and non-conventional control strategies, transfer function, dynamic response, and stability criteria, state space approach and exposure to simulation tools.
This course provides an introduction to the diverse field of biomedical engineering and its application. We will focus on the topics at the interface between engineering and biomedical science; engineering principles for physiological phenomena. The course initiates with basic understanding of biological systems pertaining to application perspective from engineering discipline. Engineering theories will be applied to explain interaction of the metals, polymers, and ceramics biomaterials with the bodily environment and corresponding surface modifications. Working principles and applications of biosensors, biomedical imaging, and tissue engineering processes will be examined. Application of nanotechnology in biomedical applications will be covered.
Introduction, structure of materials (metals, ceramics and polymers), crystalline structure imperfections, amorphous and semi-crystalline materials, correlation of structure to properties, phase diagrams & phase transformation, solidification, diffusion and heat treatment, mechanical behavior of materials.
