A 1/7 scale model is developed that simulates the dynamic response of AM2 landing mat subjected to C-5A aircraft landings. The fundamental variables include length, material stiffness, density, aircraft deceleration and velocity, coefficients of friction, tire pressure, and soil-mat interaction. The model is validated by simulating a buckling failure in prototype AM2 mat at Dyess Air Force Base. Five runway modifications are tested: (1)Restraint by pretensioned bands riveted to the mat surface; (2)diagonal laying pattern; (3)increased friction at the mat-subgrade interface; (4)cleats attached to the underside of the mat; and (5)longitudinal stiffeners.
