Mathematical simulation of enegy expenditure and recovery during sprint cross-country skiing
Purpose: A cross-country sprint competition relies on maximal effort durations of 3–4 minutes. Significant anaerobic energy contribution is expected. Anaerobic energy contribution has been estimated in different sports to ...
Calculation of decomposition products from components of gunpowder by using ReaxFF reactive force field molecular dynamics and thermodynamic calculations of equilibrium composition
The major combustion products from munitions containing nitro-based propellants are water, carbon monoxide, carbon dioxide, hydrogen and nitrogen. In addition, compounds including hydrogen cyanide, ammonia, methane, nitrogen ...
Using the Power Balance Model to Simulate Cross-Country Skiing on Varying Terrain
The current study adapts the power balance model to simulate cross-country skiing on varying terrain. We assumed that the skier’s locomotive power at a self-chosen pace is a function of speed, which is impacted by friction, ...
Experimental and numerical study of the fragmentation of expanding warhead casings by using different numerical codes and solution techniques
There has been increasing interest in numerical simulations of fragmentation of expanding warheads in 3D. Accordingly there is a pressure on developers of leading commercial codes, such as LS-DYNA, AUTODYN and IMPETUS Afea, ...
