OBJECTIVE

This  course  is  designed  to  give  an  insight  into  the  latest  developments  regarding  smart materials and their use in structures. Further, this also deals with structures which can self adjust their stiffness with load.

 

UNIT I             INTRODUCTION                                                                                                   9

Introduction  to  Smart  Materials  and  Structures  –  Instrumented  structures  functions  and response – Sensing systems – Self diagnosis – Signal processing consideration – Actuation systems and effectors.

 

UNIT II            MEASURING TECHNIQUES                                                                                9

Strain Measuring Techniques using Electrical strain gauges, Types – Resistance – Capacitance

–  Inductance  –  Wheatstone  bridges  –  Pressure  transducers  –  Load  cells  –  Temperature

Compensation – Strain Rosettes.

 

UNIT III           SENSORS                                                                                                             9

Sensing Technology – Types of Sensors – Physical Measurement using Piezo Electric Strain measurement – Inductively Read Transducers – The LVOT – Fiber optic Techniques.

Chemical and Bio-Chemical sensing in structural Assessment – Absorptive chemical sensors – Spectroscopes – Fibre Optic Chemical Sensing Systems and Distributed measurement.

 

UNIT IV          ACTUATORS                                                                                                        9
