IT IS APPLICABLE FOR ALL STUDENTS ADMITTED IN THE YEAR 2011 2012-2013 (ANNA UNIVERSITY CHENNAI,TRICHY,MADURAI, TIRUNELVELI,COIMBATORE), 2008 REGULATION OF ANNA UNIVERSITY CHENNAI AND STUDENTS ADMITTED IN ANNA UNIVERSITY CHENNAI DURING 2009
ML3311 CREEP AND FATIGUE BEHAVIOR OF MATERIALS L T P C
3 1 0 4
OBJECTIVE
The useful life of components are 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.
UNIT I INTRODUCTION 12
Strength of perfect crystal - Lattice resistance to dislocation movement – Elastic
properties of dislocation – Dislocation multiplication – Slip and twinning in crystalline
solid.
UNIT II HIGH – TEMPERATURE DEFORMATION RESPONSE 12
Creep Of Solids – Temperature stress – Strain rate relation- Deformation mechanism –
Super plasticity deformation mechanism maps – Extrapolation procedure for creep
rupture data – materials for elevated temperature rules.
.
UNIT III CYCLIC STRESS AND STRAIN FATIGUE 12
Macrofractrography fatigue failures - cyclic stress and strain controlled fatigue - Fatigue
life estimation for notched components – Crack initiation mechanisms.
UNIT IV FATIGUE CRACK PROPAGATION 12
Stress and crack lengths correlations with FCP – Fracture modes in Fatigue –
Microscopic fracture mechanisms – Crack growth behavior at Δk extremes – Influences
– Micro structural aspects of FCP in metal alloys.
UNIT V ANALYSIS OF ENGINEERING FAILURES 12
Typical defects – Microscopic surface examination – metallographic and fractographic
examination – Component failure analysis – Fracture surface preservation – Cleaning
and replication techniques and image interpretation.
TOTAL : 60 PERIODS
