ML3011 EXPERIMENTAL STRESS ANALYSIS L T P C
3 0 0 3
OBJECTIVES
After studying stress and strain in the core mechanical subjects, this elective should train
the students to apply practical methods of experimental stress analysis.
UNIT I INTRODUCTION 7
Basic Equations and plane elasticity theory – plane elastic problems - plane strain
approach – plane stress – Airy’s stress function – in cartesian co-ordinate. Two
dimensional.
UNIT II BRITTLE COATING METHODS 7
Coating stresses – Failure theories. Brittle coating crack patterns – direct load –
Defrigeration Techniques. Brittle – coating crack patterns produced by releasing the
load, double crack pattern – crack detection.
UNIT III PHOTO ELASTICITY METHODS 8
69
Stress optic law in two dimensions at normal incidence – Effect of stress model in a
plane polariscope - Circular polariscope ( Dark field – light field) – Fringe multiplication
by photographic methods. Holography
UNIT IV STRAIN MEASUREMENTS 12
Definition of strain and its relation to experimental determinations – Basic characteristic
of strain gage – Moire method – Grid method of strain analysis. Electrical resistance
strain gages, gage construction – temperature compensation gage sensitivities and
cage factor – semi conductor strain gages – Delta rosette.
UNIT V STRAIN GAGE CIRCUITS 11
Potentiometer and its applications to strain measurement - range and sensitivity of
potentiometer circuit – Temperature compensation – Load effects on the potentiometer
circuits – Wheat stone bridge – Null –balance bridge – Criteria for circuit selection.
TOTAL : 45 PERIODS
