A new model has been defined that enables the estimation of the lethal radius (radius of efficiency) of HE (High Explosive) artillery projectiles against human targets. The model is made of several modules: CAD (Computer Aided Design) modeling, fragm

A novel method for estimation of an aerodynamic force and moment acting on an irregularly shaped body (such as HE projectile fragments) during its flight through the atmosphere is presented. The model assumes that fragments can be approximated with a

The compressibility model was developed and applied to generalized model for prediction of aerodynamic forces acting on irregularly shaped body, such as HE projectile fragments. Model assumes adiabatic compression of air in front of high-velocity fra

The paper shows a way how a 3D scanner can be used in a combination with numerical simulations and corresponding analytical results to estimate deformations and stresses in a loaded structural element, such as beams, pipes, shafts, etc. To compare me
