Levitas UID:2bcac823-b403-4e60-b43b-4003c699e13b DESCRIPTION:Valery I. Levitas Iowa State University\, Departments of A erospace Engineering and Mechanical Engineering\, USA 4.

The followin g recent results on application of phase-field approaches (PFA) to mod eling PTs\, dislocation evolution\, and their interaction will be disc ussed: –\; Nanoscale PFA for martensitic PTs that satisfy crystal lattice instability conditions under the action of all six components of the stress tensor obtained from the atomistic simulations. This in cludes new interpolation functions for transformation strain and elast ic moduli. Introducing athermal interface resistance and interfacial s tresses will be discussed. Multiphase PFA will be suggested with appli cation to multivariant martensitic PTs and solid-solid PTs via interme diate melt at temperatures significantly below the thermodynamic melti ng temperature. –\; Nanoscale phase-field approach to dislocation evolution. –\; Nanoscale phase field approach to interaction bet ween PTs and dislocations. –\; Scale-free PFA to martensitic PTs\ , which does not include gradient energy\, where regularization of the problem is achieved through kinetic equations for the concentration o f martensitic variants. Practical mesh independence of the solution is demonstrated in several examples. –\; Scale-free approach to evo lution of discrete dislocation pileups\, twins\, and shear bands\, whi ch are described with the help of a contact problem in continuum mecha nics. –\; Scale-free approach to the interaction between PTs and dislocations obtained as a combination of two previous approaches.  211\; Large strain PFA for all the above processes. Various problems o n interaction between PTs and dislocations are solved DTSTART:20260804T150000Z DTEND:20260804T160000Z LOCATION:WW8\, Room 2.018-2\, Dr.-Mack-Str. 77\, Fürth DTSTAMP:20260730T060643Z END:VEVENT END:VCALENDAR
