Abstract: Significant progress in phenomenological and physical based modelling of solid materials, i.e. ceramics, metals, polymers, has been made throughout the last decades. However, environmental concerns, profitability and sustainability demands lead to complex interdependencies between processing conditions, parameter tolerances, material properties and in-service behaviour of the final product. The investigation of these interactions opened a wide field for ongoing research activities. The minisymposium addresses design, algorithmic implementation as well as validation and verification of analytical and numerical solution techniques for multi-physics and multi-length-scale problems in solids arising during optimisation and development of products and manufacturing techniques. To solve these problems, computer-aided simulation methods based on advanced analytical and numerical solution techniques for nonlinear partial differential equation systems are of continuously increasing importance. Modelling consists of describing stationary and transient physical effects acting on different time scales, involving chemical, electrical, magnetic, mechanical and thermal fields. The computational approaches comprise macro-, micro- and nano-length scales as well as couplings between fields and/or length-scales and/or time-scales. Special emphasis is to be put upon the modelling of micro- and nano-structural features, their properties and morphology evolution (including solid state phase transitions) during processing. Next to the property and behaviour modelling of final products, material performance decay under extreme loading conditions is of great interest, as e.g. corrosion in chemically aggressive media, high temperature creep, deformation of shape memory alloys, electro-chemical machining, high cycle fatigue, superconductivity at cryogenic temperatures etc. Furthermore, the minisymposium is open for contributions concerning the numerical issues inevitably arising during numerical and experimental validation and verification of the computational analysis methodologies for multi-physics and multi-scale problems. In this context the quantification of dominant physical effects, the determination of material properties and the generation of appropriate micro- and nano-structural geometries are to be mentioned. Among many others, the numerical methods of interest range from BEM, FEM (including hpFEM, SFEM, XFEM etc.) to FDM, FVM, meshfree and spectral methods. We kindly invite researchers from various disciplines to come together, review the achievements from the past and their influence on recent trends, discuss and solve current problems and contribute to the variety of next generation numerical solution techniques.
