Creep and Fatigue Behavior of Materials for B.Tech 6th sem is covered here. This gives the details about credits, number of hours and other details along with reference books for the course.<\/p>\n
The detailed syllabus for Creep and Fatigue Behavior of Materials B.Tech (R13) sixthsem is as follows<\/p>\n
OBJECTIVES:<\/strong><\/p>\n The useful life of components is often limited by the fracture, fatigue and creep properties of the materials used. The students study the fundamental processes leading to failure of technical components.<\/p>\n UNIT I : INTRODUCTION<\/strong> \u00a0 \u00a0[9 Hours] UNIT II : HIGH \u2013 TEMPERATURE DEFORMATION RESPONSE<\/strong> \u00a0\u00a0 \u00a0[9 Hours] UNIT III : CYCLIC STRESS AND STRAIN FATIGUE<\/strong> \u00a0\u00a0 \u00a0[9 Hours]
\nStrength of perfect crystal – Lattice resistance to dislocation movement \u2013 Elastic properties of dislocation \u2013 Dislocation multiplication \u2013 Slip and twinning in crystalline solid.<\/p>\n
\nCreep Of Solids \u2013 Temperature stress \u2013 Strain rate relation- Deformation mechanism \u2013Super plasticity- deformation mechanism maps – LM parameter-\u2013 Extrapolation procedure for creep rupture data \u2013 materials for elevated temperature rules.<\/p>\n
\nMacrofractrography fatigue failures – cyclic stress and strain controlled fatigue – Fatigue life estimation for notched components \u2013 Crack initiation mechanisms factors affecting fatigue-size, temp, surface condition-microstructure-soderburg and goodman equation<\/p>\n
