Machine design focuses on the basic principles of the following three areas: ▪ Mechanical behavior includes statics, dynamics, strength of materials, vibrations, reliability, and fatigue. ▪ Machine elements are basic mechanical parts of machines.
CH-1 Mechanical Engineering design – Design considerations, Design Procedure Material selection Modes of failure – Theories of failure , causes of stress concentration; stress concentration in tension, bending and torsion; reduction of stress concentration, theoretical stress concentration factor, notch sensitivity, fatigue stress concentration factor, cyclic loading, endurance limit, S-N Curve, loading factor, size factor, surface factor. Design consideration for fatigue, Goodman and modified Goodman’s diagram, Soderberg equation, Gerber parabola, design for finite life, cumulative fatigue damage
