The study of composite material behavior wherein the material is presumed homogeneous and the effects of the constituent materials are detected only as averaged apparent properties of the composite.

A material which reduces the emission of electrons from the surface of a cathode.


1. Braking an electric motor by reversing its connections, so it tends to turn in the opposite direction; the circuit is opened automatically when the motor stops, so the motor does not actually reverse. 2. The formation of a barrier (plug) of solid material in a process flow system, such as a pipe or reactor.


Laboratory device used to predict the performance of a plastic material by measurement of temperature, viscosity, and shear-rate relationships. Also known as plastigraph.


To soften a material to make it plastic or moldable by adding a plasticizer or by using heat.


To soften a material by heating or kneading. Also known as plastify.


The accidental initiation of combustion by means of contact of gaseous material with an external high-energy source, such as a flame, spark, electrical arc, or glowing wire.


A pressure-measuring gage that uses a piezoelectric material to develop a voltage when subjected to pressure; used for measuring blast pressures resulting from explosions and pressures developed in guns.


A robot component that first punctures a material such as cloth, rubber, or porous sheets, or soft plastic in order to lift and handle it. pier foundation See caisson foundation.


[CONTSYS] Aphotoelectric control system used as a position regulator for a loop of material passing from one stripprocessing line to another that may travel at a different speed. Also known as loop control.


A material which is used to store the latent heat absorbed in the material during a phase transition.
