Abstract
A rate controllable damping mechanism is disclosed. The mechanism includes a chamber disposed within a housing; an element mounted for movement within the chamber; a damping material, preferably a low melting temperature metal alloy, in the chamber for preventing the movement of the element at a first temperature and for damping the movement of the element at a second temperature; and a heater for selectively increasing the temperature of the damping material from the first temperature to the second temperature. Controlled damping is effectuated by heating the fluid material until it reaches a molten state at which the resultant fluid damps the movement of the element in a conventional manner. A novel method is also disclosed for structural stress relief.
