“…In this study, eight different force fields were used to perform simulation MD instruments, and mechanical factors such as Young's modulus, shear modulus, compressibility, and final strength of atomic structures were calculated and reported. Titscher et al 12 designed high-density concrete using molecular dynamics simulation. In this computational work, they studied the mechanical properties of condensed concrete structure and showed that this secondary structure has promising mechanical properties.…”

“…The aim of this experiment is to show the performance aspect of the IMPL-EX scheme compared to a backward Euler integration. The mesoscale geometry of the 40 mm × 40 mm × 40 mm specimen is randomly generated (Titscher and Unger 2015) from a B16 grading curve (defined in DIN 1045-2) and 60 % aggregate volume fraction. Aggregates smaller than 8 mm are assumed to be represented by the matrix material and were not resolved explicitly.…”

“…Due to the complexity of bidisperse or polydisperse sphere packings, the problem is often investigated numerically [Torquato et al 2010]. But the packing of equal spheres remains relevant for crystal forming processes, as a benchmark problem for the used algorithms [Titscher et al 2015] or for packings in higher dimensions [Skoge et al 2006]. Interestingly, randomly arranged spheres form a maximally random jammed packing (MRJ) and only reach φ MRJ ≈ 64% [Kansal et al 2002a].…”
