BACKGROUND A large proportion of the plastic surgery literature is dedicated to the breast. It is one of the most common topics in our specialty, yet it is unclear which articles have been the most influential. The purpose of this study was to identify the top 100 most-cited articles on breast in the plastic surgery literature and examine the characteristics of each individual article. METHOD...

To generate complete 3-D maps of extracellular ion current patterns around insect ovarioles without removing the sample and chamber from the recording equipment, it was necessary to design a chamber permitting complete rotation of the tissue. While suction pipets have been used in previous studies to orient the tissue (1), their use can significantly disturb extracellular ionic gradients if an ...

the present paper is devoted to a new critical state based plasticity model able to predict drained and undrained behaviour of granular material. it incorporates a bounding surface plasticity model describing in multilaminate framework to capitalize on advantages of this mathematical framework. most of the models developed using stress/strain invariants are not capable of identifying the parame...

Different experimental techniques and 3D FEM simulations are employed to characterize and analyze the three dimensional plastic deformation and residual strain/stress distribution for single crystal Aluminum under microscale laser shock peening assuming finite geometry. Single pulse shock peening at individual locations was studied. X-ray microdiffraction techniques based on a synchrotron light...

A simplified model for orthogonal micromachining of face-centered cubic (FCC) single-crystal materials is derived in this work. The model uses the basic assumptions and geometrical construction of the Merchant’s model. Bishop and Hill’s micro-plasticity model is used to determine the plastic work done to shear the material along a thin shear plane. The rotation of lattice during the deformation...

An investigation into the properties of granular materials is undertaken via numerical simulation. These simulations highlight that frictional contact, a defining characteristic of dry granular materials, and interfacial debonding, an expected deformation mode in plastic bonded explosives, must be properly modeled. Frictional contact and debonding algorithms have been implemented into FLIP, a p...

in this study, displacement field around v-notches of a poly methyl metha crylate (pmma) specimen with tip cracks will be analyzed using digital image correlation technique. first intensity factor in combination with in-plane rigid body translations and rotation components will be determined by linear least squares fitting of the displacement field data to the corresponding relations among stre...
