Übersetzung für "Plastic elongation" in Deutsch

During plastic elongation, the originally short strip fibers are elongated to a relatively stronger degree.

The plastic of greater elongation at rupture must also be thermoplastically workable, particularly coextrudable with the acrylic glass.

The strip is plastically elongated and the level of the plastic elongation is referred to as stretch ratio.

The aim of this research is to examine the possibility of de scaling wire rod by a new mechanical process, in which the rod is subjected to plastic elongation applied by a tensioning device.

There are materials which tend to crack when subjected to extensive plastic deformation, particularly elongation, if such deformation takes place at temperatures above the so-called Ac3 point, being the temperature at which the material structure changes into an austenitic phase (approximately 800° to 850° C. for steel).

F-H: range of elongation up to the point of maximum load H prior to necking and instability, and giving rise to a relatively high plastic elongation and transverse contraction.

A constant plastic elongation over the entire strip width cannot, however be achieved because the degree of dressing cannot be optionally set by conventional means.

This means that the stresses in the critical area of the capsule bottom are so markedly reduced that no thinning of the material forming the capsule bottom occurs and the deformations in the material of the capsule bottom remain within the limits of plastic elongation.

Accordingly, the rupture is always indicated by a plastic elongation of the anchor 1.

The difference between the plastic elongation in the edge regions and at the center diminishes as a result of the skin pass rolling so that the waviness is reduced.

The distribution of plastic elongation across the strip width can therefore be directly influenced via the introduced temperature differences.

The second layer likewise is composed of a fiber-reinforced plastic, the elongation at break of the reinforcement fibers being greater than 3%.

The negative effects of over-tempered martensite, such as coarse carbides, blocking plastic elongation and negatively affecting the strength of the martensite and the bending angle and hole expansion forming properties, are avoided by the heating according to the invention to the holding temperature T P, wherein optional holding at the partitioning temperature further increases the reliability of avoiding over-tempered martensite.

During the warm-up phase of the pressure casing 20, during a cold start, the casing material which surrounds the threaded bolts heats up more quickly than the shank of the threaded bolts within the through-hole 27, which, on account of the different thermal expansion of the bolts and the casing, can lead to an overload and plastic elongation of the threaded bolts with subsequent local leakages.

According to the invention, this problem is solved in a manner that is as surprisingly simple as it is effective in that at least one of the struts comprises an expandable element that forms a strut section within said strut, in which the expandable element extends partially geometrically transversely to the longitudinal axis of the strut in the contracted state, the course of the expandable element having a plurality of direction changes with respect to said longitudinal axis, and that the material, thickness and strut width of the expandable element are selected such that, by applying force in the radial direction of the tubular implant, the expandable element can be transferred by way of plastic elongation into a permanently expanded state in which the strut section forming the expandable element has a greater geometric extension transversely to the longitudinal axis and a smaller extension in the direction of the longitudinal axis than in the contracted state.

Stents must have the ability to tolerate large plastic elongation and maintain the size or diameter thereof when they are expanded.

The austenitic-ferritic steel, which is also referred to as duplex steel, is distinguished by a high plastic deformability, the elongation at break thereof being at least 25%.

In this respect, it is possible to already realize such a plastic elongation in a region prior to the production of the welding seam.

These brittle materials usually have a plastic elongation at break of less than or equal to 2%, often even less than or equal to 0.2%.

Carrying out the tensile test at a drawing rate of 0.0005 mm/min in a humid environment after the creep deformation mentioned above was interrupted at a plastic elongation of 21.4% without specimen fracture, which indicates that, unlike with the conventional heat treatment, there is no embrittlement.

Since a plastic elongation of the above-mentioned fibers is not possible, fibers that extend in the direction of the enlarging or elongation must be redrawn.

The stretching process takes the major part of the initial plastic elongation out of the rope and allows users to operate with the same minimal length tolerances that they would get when using wire ropes.

Plastic elongation is minimal in this method, meaning bolts can generally be reused.

Because of the high elongation at tear of the elastomer modified polypropylene plastic materials (the elongation at tear of plastic materials ranges in general at about several hundred percent) and due to the relatively high difference to the elongation at tear of the varnish particles (the elongation at tear of the normally used cover paints or varnishes ranges at approximately 100-150%, while the elongation at tear of the primer is significantly lesser, so that the figures of the elongation at tear of the varnish material can be rated between 50 and 200%) the varnish particles can follow the elongation of the plastic parts only partly if at all so that they chip off and flake.
