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. fragment mass distribution estimation. fragment initial velocity prediction. https://www.diegojavierfares.com/quick-grab-Cut-Out-Black-Plastic-Masquerade-Mask-flash-find/
