Origin

Mid 17th century (in the sense 'characteristic of moulding'): from French plastique or Latin plasticus, from Greek plastikos, from plassein 'to mould'.

The Greek word plastikos meant ‘able to be moulded into different shapes’, and came from plassein ‘to mould’. When plastic entered English in the 17th century it had a similar meaning, but its main modern sense is for synthetic compounds developed in the early 20th century. This sense was first used in print in 1909 by the Belgian-born scientist Leo Baekeland, inventor of Bakelite. Plastic surgery refers to the shaping or transferring of tissue, and the first mention of the use of plastic surgery in treating injury was in 1837. Plaster (Old English) comes from the same root. An early plaster was a bandage spread with a curative substance which usually became adhesive at body temperature. Use of the word to mean a soft mixture of lime mixed with sand or cement and water dates from late Middle English. Plasma (early 18th century) also comes from plassein. Its use in medical contexts, for the material from which blood is moulded or made, dates from the mid 19th century, with the ionized gas dating from the early 20th.

At this point, they are still moving around pretty fast, so they are bounced around in a nearby plastic material.

Yielding occurs from point A to point B and this is the area of plastic deformation. Normally, such plastic deformations result in developing smooth or gently wrinkled boundary surfaces. The NDT is the temperature at which fracture initiates with essentially no prior plastic deformation. Heat is also released by plastic deformation associated with jetting and ripple formation at the interface between the parts being welded. Little or no plastic deformation is seen in tracheid walls in ring 26, which is the last ring formed in the tree. There was asphalt cracking due to tensile strain resulting from plastic deformation within the crushed rock. The stress at which plastic deformation or yielding is observed to begin depends on the sensitivity of the strain measurements. This limits local concentrations of plastic deformation and suppresses fatigue damage. Ruptures originating at plastic deformations of loaded sand bed formed stretch marks with sand penetrating through them to the clay. Similar dynamics is observed in the plastic deformation of solids, in particular glasses. A significant amount of the total plastic deformation therefore occurs in the microcracks grow and link up in the final stages of fracture. Thus rigid pipes are less sensitive to crushing and more sensitive to plastic deformation and buckling than their flexible equivalents. Therefore, micropipette aspiration deforms the cell with a mixture of elastic and plastic deformations. AFM data, described below, also did not show any obvious plastic deformation after repeated indentation. Increases in axle loads and tyre pressures are creating plastic strain in some crushed rocks with sprayed seal and thin asphalt surfacings. In crystalline solids, plastic deformation tends to be confined to crystallographic planes of atoms which have a low resistance to shear. The main component of this deformation is the plastic strain of cell walls. Any attempt to do so results in greater deformation of the rolls, without any plastic deformation of the strip. It should also be added that the fine precipitate particles can act as dislocation multiplication centers during plastic deformation. Derivatives plastically adverb A fundamental assumption of elasticity when it is known that some granular and thin asphalt pavements are being plastically strained by legally or overloaded vehicles. Example sentencesExamples Schwartz and colleagues provide the first observational evidence that the giant flare was produced when the crust of the magnetar could no longer plastically compensate the internal magnetic stress and finally cracked. In a similar fashion, a soft clay will generally behave plastically, whereas an overconsolidated clay (for example, London clay) will be stiff until it reaches its yield point, when it will break up into blocks. If a flexible pipe is subject to severe bending, the innermost steel carcass may seize and plastically deform. If a cell that is a potential site of establishment for a juvenile is already occupied the stolon reacts plastically, with probability p C, by at most four additional growth steps. Origin Mid 17th century (in the sense 'characteristic of moulding'): from French plastique or Latin plasticus, from Greek plastikos, from plassein 'to mould'. The Greek word plastikos meant ‘able to be moulded into different shapes’, and came from plassein ‘to mould’. When plastic entered English in the 17th century it had a similar meaning, but its main modern sense is for synthetic compounds developed in the early 20th century. This sense was first used in print in 1909 by the Belgian-born scientist Leo Baekeland, inventor of Bakelite. Plastic surgery refers to the shaping or transferring of tissue, and the first mention of the use of plastic surgery in treating injury was in 1837. Plaster (Old English) comes from the same root. An early plaster was a bandage spread with a curative substance which usually became adhesive at body temperature. Use of the word to mean a soft mixture of lime mixed with sand or cement and water dates from late Middle English. Plasma (early 18th century) also comes from plassein. Its use in medical contexts, for the material from which blood is moulded or made, dates from the mid 19th century, with the ionized gas dating from the early 20th.

Do not put either glass or plastic in hot water; they may crack, especially if cold. Most plastics, varnishes and packaging foams are made from chemicals derived from petroleum. A bill to deal with beverage containers would discourage the use of plastic by imposing a levy on manufacturers who use plastic bottles, and would encourage the return and recycling of bottles. We had curbside recycling for paper, plastic, glass and tin cans. Her house is a shack made of sticks, black plastic and a few sheets of tin.

If your new plastic is a ‘% only on balance transfers’ card, you won't be going shopping with it. Hence, with so much plastic in circulation, Britain needs to treat its credit cards with respect. Swapping your expensive plastic for a credit card that charges no interest on balance transfers and purchases for up to nine months. Did you know that if you laid all of Britain's credit and debt cards end-to-end, the line of plastic would stretch from London to Bangkok? Some feared that the charges would erode the card's upscale position as the premium-priced plastic. So, you'd be barking mad to use any plastic abroad, other than a Nationwide BS or SAGA card. Each plastic card resembles a credit card, but is in fact a completely self contained microcomputer with its own embedded software and memory.
