T-90M RELIKT armor vs Leopard 2 DM53 APFSDS

Simulation of a Leopard 2A6 projectile hitting the frontal armor of T-90M 120mm DM53 APFSDS (~24mm WHA penetrator, WHA segmented tip) at 1700 m/s vs T-90M hull front armor: Relikt ERA (2 x HHA plate, 4S23 explosive elements) 60mm SHA NERA 60mm SHA 10mm radiation lining 50mm SHA at 68 degrees NERA (5mm rubber 3mm bulging steel 19mm air 3mm bulging steel 5mm rubber) 120mm muzzle velocity (DM53) - 1750 m/s. 1700 m/s refers to a distance of approximately 1 km. The exact documentation of the DM53 is classified. The models were created based on photos and other data. Internal design of the tip based on the patent and other indirect sources. Anticipating questions. The finite element method was used to perform this simulation. Even if there are 10 million elements, the model has a limited ability to divide into fragments. When the element reach the faliure level it turns into free “particles“ which retain the mass of the element. When a given object is severely damaged in various planes, this phenomenon may intensify and the main source of penetration will be these particles, which happened at the end of the simulation.
