Abstract
Abstract A shock attenuating support structure for equipment comprising metal material which exhibits ''''elastic-plastic'''' properties. For all operational and low intensity shock loads, the structure acts in a rigid (or elastic) manner and transmits these forces without change to the structure or its mounted equipment. For high shock loads which would normally be damaging to the equipment, the structure deforms plastically and absorbs the excess acceleration and energy.
