Multiscale Modelling and Computation of Microstructures in Multi-well Problems
نویسنده
چکیده
A multiscale model and numerical method for computing microstructures with large and inhomogeneous deformation is established, in which the microscopic and macroscopic information is recovered by coupling the finite order rank-one convex envelope and the finite element method. The method is capable of computing microstructures which are locally finite order laminates. Numerical experiments on a double well problem show that plenty of stress free large deformations can be achieved by microstructures consisting of piecewise simple twin laminates.

Dynamics of Macro–Nano Mechanical Systems; Fixed Interfacial Multiscale Method
The continuum based approaches don’t provide the correct physics in atomic scales. On the other hand, the molecular based approaches are limited by the length and simulated process time. As an attractive alternative, this paper proposes the Fixed Interfacial Multiscale Method (FIMM) for computationally and mathematically efficient modeling of solid structures. The approach is applicable to mult...
متن کاملHomogenization theory and multiscale numerical approaches for random media
We will overview a series of recent works [1, 2, 3, 4, 5, 6, 7] all related to some multiscale problems motivated by practical problems in Mechanics. The common denominator of all these works is that they address multiscale problems where the geometry of the microstructures is not periodic. Random modelling, but not only (see e.g. [2, 3]), can then be used in order to account for the imperfecti...
متن کاملMultiscale modelling of microstructure formation in polymer casting
A data bank approach to multi-scale modelling of polymer solidification under flow and holding conditions is presented with applications to injection molding. The latent heat of solidification, which acts as an input parameter for large scale simulations, is determined as a function of different process dependent parameters such as the flow speed, supersaturation and geometric properties includ...
متن کاملModelling Decision Problems Via Birkhoff Polyhedra
A compact formulation of the set of tours neither in a graph nor its complement is presented and illustrates a general methodology proposed for constructing polyhedral models of decision problems based upon permutations, projection and lifting techniques. Directed Hamilton tours on n vertex graphs are interpreted as (n-1)- permutations. Sets of extrema of Birkhoff polyhedra are mapped to tours ...
