provide objective, spatially inclusive information on the relevant parameters of interest such as runout distances, jump heights, and kinetic energies as a function of the digitised terrain. While the awareness of rock shape dependence on rockfall trajectory behaviour is well established14, only the ...
To assess the risk and to design mitigation measures10,11 a quantitative assessment of block trajectory, governed by the impact process, is mandatory. According to Ref. 12 the impact process is governed by three categories of factors: (a) slope characteristics (e.g. strength and stiffness of ...

The analytical method, describing the shape of the temporary pulsating gunshot cavity, has been presented in this paper. A non-viscous incompressible liquid approximates the tissues of the living organism. The simple algebraic formula, determining the trajectory of the rigid projectile penetrating into...
The design for an anti-aircraft hollow projectile, provided with ample power and precision, to minimize the flight time of a given slant distance is of vital importance. With the purpose of obtaining the optimal aerodynamic shape with the shortest possible spent time of a given slant distance, ...
The study utilizes an aerodynamic force engineering algorithm and numerical trajectory calculations to obtain the projectile's performance responses within the Latin hypercube design space. To enhance optimization efficiency, a stochastic Kriging surrogate model is established to capture the inherent ...
