- Capillary Viscometer
Measures the time of flow of a measured volume of solution through a capillary tube under the force of gravity is compared with the time taken for the same volume of pure solvent, or of another liquid of known viscosity to flow through the same capillary.
- Chord
A chord of a curve is a geometric line segment whose end points both lie on the curve. A secant or a secant line is the line extension of a chord.
- Chord Modulus
The chord modulus is the slope of the chord drawn between any two specified points on the stress-strain curve.
- Cleavage Strength
Tensile load divided by sample width required to cause separation of an adhesive bond.
- Climbing Drum Peel
Fixture designed to peel bond between sandwich type material usually having one rigid and one flexible surface.
- Coefficient of Elasticity
An alternative term for modulus of elasticity.
- Coefficient of Kinetic Friction
The ratio of friction force to normal force once slippage has begun between two objects in contact.
- Cofficient of Static Friction
A ratio measure of how much force is required before an inert object, of a given material, at rest on another known substance, can be put into motion.
- Cohesive Strength
Measure of force / area of two substances that stick to each other.
- Cohesiveness
Stickiness.
- Compressibility
The ability to be compressed.
- Compression
Application of a force to reduce a samples height.
- Compression Set
Deformation which remains in a sample after has been subjected to and released from a specific compress stress for a definite period of time at a prescribed temperature.
- Compressive Deflection
The distance that a sample is compressed.
- Compressive Deformation
Extent to which a material deforms under a crushing load.
- Compressive Strength
The measured resistance of a specimen to axial loading when expressed as force per unit area.
- Compressive Yield
The stress at which a material deforms found from the stress / strain curve.
- Conventional Stress
Conventional stress, as applied to tension and compression tests, is force divided by the original gauge length or height.
- Creep
Strain caused by stress that occurs over time.
- Creep Distance
Measurement of the distance a sample changes due to creep.
- Creep Rate
Rate of change of a sample due to creep.
- Creep Recovery
Measurement of the distance a sample returns to its original size after a creep test.
- Crush Test
Alternative name for a compression test, usually to fracture or break.
- Crystalline
Sample where the molecules are arranged in an irregular order.
- Curing Strength
Point at which a sample that requires time to cure achieves its maximum strength.
- Cycling
Exercising a sample between limits for a duration of fixed number times.
