Effects of anchor head shapes on loading anchors on debris structures were investigated through numerical simulations and experiments. Four types of anchor head shapes, cone, flat, sphere and double bladed, were employed and their penetration behaviors were numerically analyzed and compared. It was observed from the results that the minimum penetration velocity of double-bladed head was lower than those of the other head shapes and it indicates that the required kinematic energy for capturing can decrease. Then, the experiments on capturing using metal anchors with the double-bladed head have been carried out. It was also observed from the experimental results that the pulling strength using the metal anchor with double-bladed head was very small and it is difficult to achieve an appropriate capturing state. Some mechanisms will be required to the anchor with double-bladed head shape for capturing space debris.
