Modelling progressive failure in multi-phase materials using a phase field method

Phase-field method and Materials Genome Initiative (MGI)

Predicting and controlling the microstructure evolution within a material are considered as the ‘‘holy grail’’ of materials science and engineering. Many important engineering materials are designed by controlling their phase transformations and microstructure evolution. Examples include the improvement of mechanical properties through solid-state precipitation reactions in Nibased superalloys ...

OPTIMALIZATION PHASE USING GRAPH MODELLING FOR RELIABLE BUILDING COMPLEXES

During the planning phase of modern, complex, block-structured, large-area located, but still landscape-harmonized health-care buildings, the key is the optimal positioning of the blocks and functions, simultaneously ensuring the most-effective backup-paths for any transportation route failure in the buildings in order to speed up system operation, reduce maintenance costs and especially to imp...

Lecture 15 : Phase Field Modelling

Phase-field models in materials science

The phase-field method is reviewed against its historical and theoretical background. Starting from Van der Waals considerations on the structure of interfaces in materials the concept of the phase-field method is developed along historical lines. Basic relations are summarized in a comprehensive way. Special emphasis is given to the multi-phase-field method with extension to elastic interactio...

A Two-Phase Hybrid Heuristic Method for a Multi-Depot Inventory-Routing Problem

In this study, a two phase hybrid heuristic approach was proposed to solve the multi-depot multi-vehicle inventory routing problem (MDMVIRP). Inventory routing problem (IRP) is one of the major issues in the supply chain networks that arise in the context of vendor managed systems (VMI) The MDMVIRP combines inventory management and routing decision. We are given on input a fleet of homogeneous ...
