On the characterization of geometrically necessary dislocations in finite plasticity
We develop a general theory of geometrically necessary dislocations based on the decomposition F=FeFp. The incompatibility of Fe and that of Fp are characterized by a single tensor G giving theExpand
Geometrically necessary dislocations in viscoplastic single crystals and bicrystals undergoing small deformations
In this study we develop a gradient theory of small-deformation single-crystal plasticity that accounts for geometrically necessary dislocations (GNDs). The resulting framework is used to discussExpand
Transport relations for surface integrals arising in the formulation of balance laws for evolving fluid interfaces
We establish transport relations for integrals over evolving fluid interfaces. These relations make it possible to localize integral balance laws over non-material interfaces separating fluid phasesExpand
The Motion of Screw Dislocations in Crystalline Materials Undergoing Antiplane Shear: Glide, Cross‐Slip, Fine Cross‐Slip
Dislocations may be described at two levels: (i) at the continuum level a dislocation is a singularity in the deformation field that arises when a layer of material is removed and the new surfacesExpand
Sexually Antagonistic Selection in Human Male Homosexuality
Several lines of evidence indicate the existence of genetic factors influencing male homosexuality and bisexuality. In spite of its relatively low frequency, the stable permanence in all humanExpand
Renormalized Energy and Forces on Dislocations
In this work we discuss, from a variational viewpoint, the equilibrium problem for a finite number of Volterra dislocations in a plane domain, obtained by a finite-core regularization of the elastic-energy functional. Expand
Computational mate choice: Theory and empirical evidence
The present review is based on the thesis that mate choice results from information-processing mechanisms governed by computational rules and that, to understand how females choose their mates, weExpand
Dislocation Patterns and Work-Hardening in Crystalline Plasticity
Abstract We propose a continuum model for the evolution of the total dislocation densities in fcc crystals, in the framework of rate-independent plasticity. The basic physical features which areExpand
Sharp-Interface Nematic–Isotropic Phase Transitions without Flow
Abstract.We derive a supplemental evolution equation for an interface between the nematic and isotropic phases of a liquid crystal when flow is neglected. Our approach is based on the notion ofExpand
Sampling and assessment accuracy in mate choice: a random-walk model of information processing in mating decision.
Mate choice depends on mating preferences and on the manner in which mate-quality information is acquired and used to make decisions. Expand
