SHOCK MITIGATION WITH LIGHTWEIGHT VERMICULITE CONCRETE

THE IMPACT CUSHIONING CHARACTERISTICS OF LIGHTWEIGHT VERMICULITE CONCRETE ARE PRESENTED IN THE FORM OF ACCELERATION-TIME AND STRESS-STRAIN CURVES. DATA ARE INCLUDED WHICH SHOW THE EFFECT OF IMPACT VELOCITY AND MATERIAL THICKNESS ON THE CUSHIONING PROPERTIES. THE MEASUREMENT TECHNIQUE USED IS A VARIATION OF THE ONE USED AT THE DROP-TEST FACILITY FOR THE DETERMINATION OF THE PROPERTIES OF CUSHIONING MATERIALS, THE ESSENTIAL DIFFERENCE BEING THAT THE FORCE SENSING DEVICE, AN ACCELEROMETER, IS ALLOWED TO MOVE. ALSO, IMPACT ENERGY IS PROVIDED BY A PROJECTILE FIRED FROM AN AIR GUN, INSTEAD OF A FREELY FALLING MASS.
