DTC10-125/BTA-4有对于爆炸反应装甲和对复合装甲的特化效能
ERA The traditional cylindrical rod in Explosive Reactive Armor (ERA) tends to concentrate stress, and a single shear band running through it has a very high probability of fracture. In contrast, non-circular cross-section long rods (stellate rods) have multiple principal stress paths; the segmentation of crack propagation reduces the likelihood of fracture failure, creating non-uniform instantaneous deflection that generates self-stabilizing moments, making it easier to penetrate the Explosive Reactive Armor (ERA). The non-circular cross-section long rod (stellate rod) improves structural stability during the penetration process by altering stress distribution and yaw growth behavior, thereby reducing performance loss caused by fracture and instability. This indicates that the DTC10-125 is more capable of penetrating Explosive Reactive Armor (ERA), and its higher initial velocity also ensures stability, enhancing its kinetic energy penetration depth.
CA/NERA Non-circular cross-section action mechanism: by changing the initial contact stress distribution, the fragmentation behavior of a non-circular structure leads to an asymmetric debris cloud, making it less likely to completely pulverize the projectile and slightly increasing resistance to lateral shear disturbances.
This implies that the number of expelled fragments should be increased to improve the probability of penetration.
ERA 传统的圆形杆对于爆炸反应装甲(ERA)应力较为集中，单一剪切带贯穿有极高的断裂概率，而非圆截面长杆(星状杆)有多主应力路径，裂纹扩展被分割意味着其断裂失效的概率降低，造成非均匀的瞬时偏转产生自稳定力矩，更容易贯穿爆炸反应装甲(ERA)。非圆截面长杆(星状杆)通过改变应力分布与yaw增长行为，提高侵彻过程中的结构稳定性，从而降低断裂与失稳导致的性能损失，这意味着DTC10-125是更容易贯穿爆炸反应装甲(ERA)且较高的初速也保证了它的稳定性，提高了其动能穿深。
CA/NERA 非圆截面作用机制：改变初始接触应力分布，碎裂行为非圆结构会导致碎裂云不对称更不容易完全粉碎弹体抵抗横向剪切扰动略增强。
这意味着应该提高带出破片数量，提高击穿概率。
