The IWM investigates the inclusion and migration of hydrogen atoms in iron and nickel using quantum mechanics and atomistic Laptop simulations. The susceptibility on the metals to hydrogen embrittlement could be concluded from...
Nonlinear material styles, multifunctional materials and hysteresis in connection with elasto-plastic processes
A lot of parts in contemporary equipment depend on certain properties of so-referred to as multifunctional materials. These materials are distinguished by The point that therein properties like elastic deformability, thermal expansibility, magnetizability, or polarizability interact nontrivially like As an example within a piezo-crystal. At WIAS coupled styles describing these Homes are designed and analyzed.
give you pragmatic entry to the various options of atomic materials modeling via customized alternatives.
decrease demo-and-error loops by hunting the big scope of alternatives of materials development and optimization speedily and successfully.
What's decisive for substantial improvements and innovations during the regions of performance, reliability, existence or economic viability will be the integral approach or, the place applicable, the coupling together of information from unique scales and the following of alterations in material Homes around a number of process methods. Built-in computational materials engineering (ICME) is definitely the Device for quantitively describing the associations among system techniques, material microstructure, material Attributes and component conduct.
In most cases the Fraunhofer IWM obtains the relevant material Houses experimentally, establishes the affiliated design parameters and develops strategies click here and algorithms. Material Attributes are predicted in Digital examination laboratories, together with the protection and service lifetime of parts.
The Material Modeling and Structural Assessment investigate staff focuses on the structural Assessment of fiber reinforced plastics as well as mechanical and bonded joints at distinctive length scales.
Multiscale modeling to the Digital development of polycrystalline materials; reliability and very long lifetime of carbide, nitride and oxide ceramics.
Slender films Engage in an important position in mother nature and many areas of technological programs. Especially on micro- and nanoscales technological processes for instance dewetting or epitaxial growth are accustomed to structure surfaces with precise material Qualities.
Validate interactions of resource materials and manufacturing measures with material Attributes and functions.
Hard magnets Enjoy an important role in converting electromechanical Vitality in electromobility applications and wind turbines. The improved demand for materials containing scarce earth metals has, nevertheless, arrived at a vital degree.
This work is focussed on the modeling of damage and on phase separation in modern day solder materials for microelectronic equipment.
