This paper is concerned with the ratcheting prediction for steels. The yield surface evolution is integratedin the elastoplasticity analysis by a new proposed model. First, the new proposed model of DistortionalYield Surface (DYS) is developed and then ratcheting under different uniaxial and multiaxial cyclicloadings is investigated. The capabilities of the DYS model is assessed by using the results of variousstress-controlled and strain-controlled tests under uniaxial loading condition and the cyclic uniaxial experimentalresults of Hassan and Kyriakides (1994a).

There is up to 3 years funding available for a postdoctoral fellowship in computational stochastic mechanics pertaining to microstructure property relationships in metal alloys. The position is open to US citizens and permanent residents. Please see the link below for more details as well as by sending an email to: kirubel.teferra [at] nrl.navy.mil. Thank you.

    Graphene as a typical two dimensional (2D) crystal membrane attracts tremendous interest. Geometrical distortion such as nanoscale buckling morphology is widely observed in these 2D materials and is crucial to modulating the electronic properties [1]. The calculated bending stiffness of graphene is found to be the same order as that of the lipid bilayer [2], therefore buckling instability may easily occur in graphene leading to non-planar configurations.
