This case report presents an implant-aided prosthetic treatment in which peri-implant plastic surgery techniques were applied in combination to satisfactorily attain functional aesthetic expectations. Peri-implant plastic surgery enables the successful reconstruction and restoration of the balance between soft and hard tissues and allows the option of implant-aided fixed prosthetic rehabilitation.
Geometrically exact elastoplastic rods: determination of yield surface in terms of stress resultants
Abstract This work addresses the determination of yield surfaces for geometrically exact elastoplastic rods. Use is made a formulation where rod subjected to an uniform strain field along its arc length, thereby reducing problem full just cross-section. By integrating plastic and stresses over rod’s cross-section, one then obtains discrete points surface in terms stress resultants. Eventually, ...
determination of the deformation length is one of the first steps in roll forming design. roll forming industries are very interested in explicit simple relationsfor prediction the deformation length without using trail-and-error methods at workshop or time consuming finite element simulations. in this paper, elastic properties and work-hardening behaviour of the strip are considered in additio...
Variable cross-section roll forming is a new process developed on the basis of traditional constant forming. It can produce variable products flexibly and efficiently, which great significance to automobile lightweight. In this paper, rolling section longitudinal beam simulated, finite element model sheet metal established in ABAQUS software, deformation stress distribution are analyzed. conclu...
an evolutionary structural optimization (eso) method is used for plastic design of frames. based on safe theorems some criteria are derived and made an effort to satisfy them during the optimization process. in this regard, equilibrium is checked and yield condition is gradually satisfied during the optimization process. in this method, the amount of used material and the stiffness for each ele...
Plastic surgery is a unique specialty that defies definition, has no organ system of its own, is based on principles rather than specific procedures, and, because of cosmetic surgery, is the darling of the media. What is plastic surgery? No complete definition exists. Joe McCarthy defines it as the “problem-solving specialty.” My wife, an anesthesiologist, calls plastic surgeons the “finishers”...
This paper reports the dependences that have been derived to determine effective width of a free flange in dangerous cross-section wide-flange hull girder with breaking wall/edges/axis at elastic-plastic deformation depending on applied load for perfectly plastic material without strengthening. Currently, there are no systematic girders this type, except certain cases. The technique is suitable...
