One of the specialty of ATOA Scientific Technologies, is the Multiscale modeling for both length and time scale for applications engineered from atomic level.
Quantum mechanics captures the elementary particle physics and is all that we need to solve any scientific and engineering problems. The practical solution and analysis of quantum mechanical equations for real life problems is limited due to large number of atoms and the associated degree of freedom. The homogenization of quantum mechanics into physics helped us to solve many scientific problems with a reasonable accuracy.
A Journey through length scale starts from sub atomic particle to atoms to molecules to compounds to materials to products to engineering applications. The macro engineering behavior is the cumulative effect starting from the subatomic particles. The science and engineering evolved from probing atomic particles.
Various models are available in predicting the properties and performance at both length and time scale from nano to micro to macro scale properties. Linking the length and time scale allows us to probe macro engineering behavior into the atomic level origin.
Recent developments in Multiscale modeling make this as a practical possibility for solving real engineering problem. Multiscale model is a mathematical model formed by combining partial model at different length and time scales.
There are four length scales material models, continuum mechanical models , micro structure models, atomistic models and electronic structure modes. These models span from macro to micro to nano meter length scales.
The Multiscale modeling ultimate objective is to connect to the atomic level. However, for many applications even if we step one up or down is good for exploiting the Multiscale modeling capability. For examples, stepping down one scale for composites will help us to leverage micromechanics for designing composites at constituent level. Similarly, damage mechanics can help us study the damage at fiber and matrix level than a homogenized laminate level for accurate and reliable prediction of failure. |
