On the divergence of the composition of irregular fields with BV functions
Graziano Crasta, Virginia De Cicco, Annalisa Malusa
We introduce a family of (nonlinear) pairing measures that ensure the validity of the divergence rule for composite functions , where $\boldsymbol{B}(\cdot,…
Phase-field approximation of sharp-interface energies accounting for lattice symmetry
Sergio Conti, Vito Crismale, Adriana Garroni +1
We present a phase-field approximation of sharp-interface energies defined on partitions, designed for modeling grain boundaries in polycrystals. The independent variable takes val…
On a Differential Model for Sandpiles Growing in a Silo
Graziano Crasta, Annalisa Malusa
We discuss some features of a boundary value problem for a system of PDEs that describes the growth of a sandpile in a container under the action of a vertical source. In particula…
Representation formulas for pairings between divergence-measure fields and functions
Giovanni E. Comi, Graziano Crasta, Virginia De Cicco +1
The purpose of this paper is to find pointwise representation formulas for the density of the pairing between divergence-measure fields and BV functions, in this way continuing the…
Duality arguments for linear elasticity problems with incompatible deformation fields
Adriana Garroni, Annalisa Malusa
We prove existence and uniqueness for solutions to equilibrium problems for free-standing, traction-free, non homogeneous crystals in the presence of plastic slips. Moreover we pro…
Non-coercive radially symmetric variational problems: Existence, symmetry and convexity of minimizers
Graziano Crasta, Annalisa Malusa
We prove existence of radially symmetric solutions and validity of Euler-Lagrange necessary conditions for a class of variational problems such that neither direct methods nor indi…
