a) Dislocations can appear in amorphous materials.
b) A Voight model fully describes the mechanical behavior of most real polymers.
c) The compliance of a testing frame is only important when one is testing a really compliant material.
d) xx =  * xx
e) Hole-drilling is a good way to fix a crack, because the hole adds compressive stresses to the crack tip.

  • Define Non-Destructive Testing and Non-Mechanical Properties

    Section 3 Choose one of the following areas and outline some of the properties which can be defined and how these apply to metals, polymers and ceramics. within the context of this section define examples of materials which exhibit good properties and

  • Tacticity in Polymers

    Polymers that are formed by free-radical mechanisms such as polyvinylchloride are usually atactic. Due to this random nature of arrangement, atactic polymers are usually amorphous.

  • Organic Problems - matching compounds, describing reactions

    Amorphous polymers that have the ability to stretch out and spring back to their original shape 54. Bakelite is this type of polymer 55. a Ziegler-Natta catalyst 56.

  • Defluorination & adhesion properties

    In addition, the increased polarity/interpolymer attraction influences penetrants' permeation of the resin's amorphous component. However, the presence of hydrogen or of hydrogen and chlorine sacrifices chemical and thermal stability.

  • Second Order Non-Linear Optical Behavior

    The symmetry of a bulk organic material is given by the intrinsic symmetry of its constituent moieties and by their spatial ordering. Thus, both the molecules themselves and their spatial orientational distribution have to be non centrosymmetric.

  • Polyethylene Density

    Meanwhile, LDPE is entirely amorphous, and is transparent because the energy of visible light is not high enough to interact with the strong covalent bonds in the material.

  • Polarity, bond dissociation energy of molecules

    This is due to the orderly arrangements formed by crystalline materials and disorderly arrangements of amorphous materials. The more molecules per unit volume, the greater the density.

  • Current and emerging nonvolatile RAM technologies

    SONOS has theoretically higher reliability and lower voltage requirements than Flash. Phase Change Memory - Uses a chalcogenide and localized heating to change this material from crystalline to amorphous. Amorphous = 0, Crystalline = 1.

  • Redox cycling process in a conducting polymer membrane

    Conducting polymers can be used as electro-mechanical actuator materials. The actuation mechanism is based on the migration of ions in and out of the polymer during redox cycling.
