Quasicontinuum Approach Applied to Inelastic Materials

Popis výsledku v původním jazyce

The quasicontinuum (QC) method was proposed by Tadmor, Ortiz and Phillips in 1996. This method is a combination of continuum and atomistic approaches. The key idea of QC is to reduce the computational cost by reducing degrees of freedom (DOF) of the fully atomistic approach. Instead of dealing with all atoms, a small relevant subset of atoms is selected to represent the whole system. These atoms, the so-called repatoms, are used to approximate the DOF of other atoms. The original application of this computational technique was a simulation of large atomistic systems with regular lattices described by long-range conservative interaction potentials. In this work, this technique is applied to an irregular set of particles connected by discrete links representing a homogeneous material. Several models with dierent levels of simplication based on the idea of QC are provided for both elastic and plastic materials. Models for plastic materials are constructed within the framework of the micro
