DEPA
has the following broad applications :
- Measurment of Elastic Properties of Materials / Products
- Process Control
- Quality Assurance & Bulk Inspection of Products (using
GO-NO GO sorting). automation ready outputs.
- Classification of Products
- Testing of Effects of Various Processes (such as aging,
freeze-thaw resistance, cyclic loading, etc.)
Applications of DEPA are discussed in greater
detail for various materials / products below :
Abrasives : Determination of Young's
Modulus of centreless grinding wheels, honing/superfinishing stones,
crankshaft wheels, etc.; Quality assurance, bulk inspection &
sorting of vitrified /resin/ shellac/rubber/plastic bonded
abrasives.
Alloys : Measurement of elastic
properties of alloys, effects of rolling, grain orientation, powder
metallurgy, sintering process and nodularity of cast iron.
Cement & Concrete : Monitoring the effects of salt water
immersion and cyclic loading; Assessing freeze thaw resistance.
Ceramics : Study of ceramic bonds,
thermal cycling, optimization of bonds and testing of building
materials on testing line.Composites & Space Age Materials :
Studying fatigue damage, curing, aging and failure prediction of
composites and light alloys for aerospace applications.
Graphite : Testing of full size
electrodes and cores. Measurement of elastic properties of critical
components.
Refractories : Thermal shock testing,
performance prediction of critical components by measurement of
elastic properties.
Rubber and Rubber Composites :
Determination of Young's Modulus and damping at low strains.
Structures : Wire stiffness
measurements, honeycombs, bonded materials and studying the effects
of hardners.
Wood & Wood Products : Timber
segregation, impregnation and bonding in relation to mechanical
properties; Testing of chipboard products with or without laminates.
