For the tangential sliding and rolling of particle are influenced by the friction between the particles, in addition to the Poisson's ratio, shear modulus and density of the materials properties of particles, the friction coefficient of particles should be defined in EDEM.
In addition to the Poisson's ratio, shear modulus and density of the materials properties of sleepers and tamping tines, the dynamic properties of tamping tines should be defined in EDEM.

Non-oxide composites are interesting materials for long term applications at high temperature under oxidizing atmosphere.
Introduction Space and aeronautic applications need light materials with good mechanical properties even at high temperature.
For example in airplane engines, the materials have to maintain their good longterm mechanical properties under high temperature and oxidizing atmospheres even when subjected to complex mechanical loads.

As the warm-up parts have special requirements to materials, it should not be ignored. 3) As there are lots of candidate slabs in the yards, the scale of the problem becomes even larger when it comes to parallel planning.
That means start from the staple initial slab of the rolling unit, warm-up materials are be chosen first to build up the inverted confined shape of the plans.
