Structural Integrity Analysis of Engineering System

Dynamics
Instructor: D. Giagopoulos
Kinematics of particles (position vector, velocity, acceleration, rectangular coordinates, cylindrical coordinates, tangential coordinates, relative motion), Kinetics of particles (Newton’s and Euler’s laws of motion, principles of impulse and momentum, principles of work and energy), Kinematics of rigid bodies (translation, pure rotation, plane motion, rotation about a fixed point, spatial motion, relative motion), Kinetics of rigid bodies (inertia tensor, Newton’s and Euler’s laws of motion, principles of impulse and momentum, principles of work and energy, inertia forces), Applications (eccentric impact, balancing of rotating rigid bodies, axisymmetric rigid body rotation).

Mechanical Vibration and Machine Dynamics
Instructor: D. Giagopoulos
Free vibration and forced response of single degree of freedom linear oscillators to impulsive, harmonic, periodic and transient excitation (natural frequency, damping ratio, resonance). Response of multiple degree of freedom linear oscillators (formulation of the equations of motion, determination of natural frequencies and mode shapes, modal analysis). Axial, torsional and bending vibration of bars. Applications (measurement and evaluation of vibration characteristics, vibration isolation, vibration absorption, balancing, torsional vibration).
The course, beyond the theoretical teaching, introduces the student and into programming, based on application programs in an environment of MATLAB.
In the course, three (3) laboratory exercises are conducted from which students are informed about the experimental methods in vibrations of mechanical systems and have the opportunity to see the connection of the theory with the actual constructions.
