✦ Synopsis

This paper describes the numerical modelling of the repair of an explosively formed crater. The crater is repaired by in®lling with compacted material and covering the repair with a layer of rapid setting ¯ood grout concrete. The paper suggests minimum Young's modulus requirements for the crater in®ll and for the ¯ood grout. The results show that a load distributed between two wheels produces lower runway de¯ections and stresses than the same load on a single wheel. Three further research areas are identi®ed: ®rst, laboratory testing of ¯ood grout less than 1 h old; second, the establishment of the relationship between the Young's modulus, compressive strength and ¯exural strength of the ¯ood grout up to 28 days old; and third, the interface eects between the crater repair and the existing runway.

Hydrocode numerical simulations have been made for 1100-O aluminum rods into thick plates of the same material with parametric variations in the penetrator length to diameter ratio ( L/D from % -10) and impact velocity (1 -6 km/s). The normalized penetration depth (P/L), primary penetration (P,/L),
