Seminar Variational Models for Microstructures and Phase Transformations (SoSe 2020)

Announcement:

Content:

Shape-memory alloys are materials which undergo a solid-solid, diffusionless phase transformation. The high temperature phase (austenite) is characterised by a highly symmetric lattice structure. The transition to the low temperature phase (martensite) is accompanied with a loss of symmetry which gives rise to many fascinating physical properties of the material (e.g. a memory).

In this seminar we will deal with the mathematical description, analysis and prediction of microstructures in these and related phase transformation problems. Central questions and methods here are the analysis of the n-gradient problem, gradient Young measures and singularly perturbed variational problems.

Participants:

Previous knowledge in functional analysis and pdes are beneficial but not required. It is possible to attend this seminar in parallel to the lecture on functional analysis 1.

Date:

Friday, 14:15-15:45.
