Work hardening, also known as strain hardening, is the process by which a material's load-bearing capacity (strength) increases during plastic (permanent) deformation. This characteristic is what sets ductile materials apart from brittle materials. [1] Work hardening may be desirable, undesirable, or inconsequential, depending on the application.
C-4 or Composition C-4 is a common variety of the plastic explosive family known as Composition C, which uses RDX as its explosive agent. C-4 is composed of explosives, plastic binder, plasticizer to make it malleable, and usually a marker or odorizing taggant chemical. C-4 has a texture similar to modelling clay and can be molded into any ...
t. e. In physics and materials science, plasticity (also known as plastic deformation) is the ability of a solid material to undergo permanent deformation, a non-reversible change of shape in response to applied forces. [1] [2] For example, a solid piece of metal being bent or pounded into a new shape displays plasticity as permanent changes ...
The triboelectric effect (also known as triboelectricity, triboelectric charging, triboelectrification, or tribocharging) describes electric charge transfer between two objects when they contact or slide against each other. It can occur with different materials, such as the sole of a shoe on a carpet, or between two pieces of the same material.
The temperature was already above 80 degrees and rising. The work of maintaining the public water supply in a heat wave is crucial. But it needs to be done as safely as possible. That means ...
There is no national plastic bag fee or ban currently in effect in the United States.However, the states of California, [1] Colorado, [2] Connecticut, [3] Delaware, [4] Hawaii (de facto), Maine, New Jersey, [5] New York, [6] Oregon, [7] Rhode Island, Vermont [8] and Washington [9] and the territories of American Samoa, Guam, Northern Mariana Islands, United States Virgin Islands and Puerto ...
Plastic water bottles have been wreaking havoc on the environment for years, but now scientists are saying that you shouldn't use them at all if you don't want to wreak havoc on your own health ...
A shaped charge is an explosive charge shaped to focus the effect of the explosive's energy. Different types of shaped charges are used for various purposes such as cutting and forming metal, initiating nuclear weapons, penetrating armor, or perforating wells in the oil and gas industry . A typical modern shaped charge, with a metal liner on ...
