Deformities following Reconstructive Plastic Surgery
The Journal of Dermatologic Surgery and Oncology, 1987Abstract Reconstructive plastic surgery provides a surgical solution for congenital and acquired abnormalities. Donor site distortions may occur and recipient sites will be adversely affected as a result of contraction in the wound healing process. Some of the operations illustrated here had inadequate indications.

Incompatible deformations – plastic intermediate configuration
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2008AbstractThere are many approaches in continuum mechanics involving incompatible deformations, one well‐known example being the polar decomposition of the deformation gradient tensor. Such deformations have in the past been regarded rather in the context of local configurations.

Neck Deformities in Plastic Surgery
Facial Plastic Surgery Clinics of North America, 2019This article provides facial plastic surgeons with the insight to avoid and address common pitfalls in neck procedures. Many aesthetic issues are created from overtreatment or undertreatment of components of the neck. Using the platysma muscle as the divide, ease of access to superficial anatomy leads to overtreatment problems, whereas difficulty of ...

Annual Review of Materials Science, 1979
Adiabatic plastic deformation may play a role in such widely diverse areas as ballistic impact, explosive fragmentation, cryogenic behavior of materials, high velocity shaping and forming, machining, grinding 0), surface frictional effects, erosion (2), and seismic faulting.

Plastic Deformations in Complex Plasmas
Physical Review Letters, 2011Complex plasmas are macroscopic model systems of real solids and liquids, used to study underdamped dynamics and wave phenomena. Plastic deformations of complex plasma crystals under slow uniaxial compression have been studied experimentally and numerically.

Thennoluminescence in Plastically Deformed KBr
physica status solidi (b), 1963AbstractThe thermoluminescence of plastically deformed KBr crystals is measured in the temparature range 80‐350 °K for differing amounts of deformation. It is found that the glow peaks characteristic of undeformed crystals are greatly enhanced but that no new glow peaks appear.The effect of annealing at different temperatures, before X‐ray excitation ...

Plastic Deformation Mechanisms
2019This chapter begins with an introduction of the crystalline structure and crystalline defects of solid materials and the definition of hot and cold work. Then, a full description of the dislocation slip mechanism is presented, including an explanation of the direct observation of dislocations by transmission electron microscopy.

Plastic Deformation Structures
2005Abstract Plastic deformation can occur in metals from various mechanisms, such as slip, twinning, diffusion creep, grain-boundary sliding, grain rotation, and deformation-induced phase transformations. This article emphasizes on the mechanism of slip and twinning under cold working conditions.

1937
§ 1. Plastic deformation of solid matter under high confining pressures has been insufficiently studied. Jeffreys 1) devotes a few paragraphs to deformation of solid matter as a preface to his chapter on the isostasy problem. He distinguishes two properties of solid matter with regard to its behaviour to external forces: the Rigidity and the Strength ...
