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…

A well-posed variational approach to the identification and convergent approximation of material laws from boundary data
Sergio Conti, Michael Ortiz
We formulate the problem of material identification as a problem of optimal control in which the deformation of the specimen is the state variable and the unknown material law is t…
