Efficient and accurate simulation of the deformations in anisotropic metallic sheets requires a constitutive model and an accompanying algorithm at large strains which take into account the anisotropy of both the elastic and plastic material behaviors, as well as their evolution with plastic strains. Recently we proposed such a constitutive model based on continuum energy considerations, the Le...

A new class of artificial atoms, such as synthetic nanocrystals or vortices in superconductors, naturally self-assemble into ordered arrays. This property makes them applicable to the design of novel solids, and devices whose properties often depend on the response of such assemblies to the action of external forces. Here we study the transport properties of a vortex array in the Corbino disk g...

In the current practices of structural design, the concept of moment redistribution in conjunction with linear analysis is well known and widely accepted. There are numerous studies and various references that deal with the issue and different codes propose various provisions for the amount of permissible redistribution. Despite numerous advantages, there are some limitations in the available w...

The tensile deformation response and texture evolution of aluminum alloyed Hadfield steel single crystals oriented in the h169i direction is investigated. In this material, the strain hardening response is governed by the high-density dislocation walls (HDDWs) that interact with glide dislocations. A microstructure-based visco-plastic self-consistent model was modified to account for mechanical...

Steel beam cross sections are normally classified according to the effect of local buckling on the moment capacity of the section. This is achieved by defining slenderness limits for the flange and the web. This paper describes a series of bending tests on cold-formed RHS to examine these limits. The resulting experimental relationship between web slenderness and plastic rotation capacity is gi...

The ideally repaired cleft lip should provide a symmetrical Cupid's bow, philtrum, and minimal scar. In the appearance of the upper lip, the philtrum plays a key role. The most popular method for unilateral cleft lip repair is the rotation advancement technique introduced by Millard. This technique requires the rotation of the non-cleft-side flap in a unilateral cleft lip. As the vertical discr...
